@@eyeshezzy I have only 1 so far and planning to get a 2nd. This sub is a beast. It has speed because of small woofers, but can go deep like larger driver subs can. It's a jack of all trades sub. I think anyone would be shocked at just how much output it has, and in person it's even smaller than you'd think. I've had alot of subs as well, SVS, PSA, Rythmik, REL, HSU, and more.
I can't believe the engineering KEF put into this small room friendly sub. I'm also glad to hear that it's a very good music sub too as my system is 50/50.
The engineering behind KEF subs have astounded me - not cheap, but in this case you most definitely get what you pay for. Great review / thanks to you Nano and Sean.
@@NemoPropaganda Hi!! Your videos are very good! I have a question that you always use 2 subs!! How good is the pairing if I put a Rel T9i next to a Kef 92 as a second sub? Thank you
@@tibitibi1407 I don't think it is a good idea to mix subwoofer brands unless their design is very similar. Here you have 1 dual opposed sealed sub with DSP and another fully analog sub without dsp. I would not mix these 2 at the same time personally. I generally think mixing within the same brand is okay even if the size is different but mixing other brands together can be very hit or miss and is usually a miss. Instead sell one and get a pair that matches. The results will be much better for the money spent :)
@@NemoPropaganda Thank you very much for your help...I would like a Kef 92 first, then later I will need a second one..Do you have a good opinion of the Kef 92 subwoofer? Film and music 50-50%!! thank you
@@tibitibi1407 yes I love it, if you need a compact solution that can extend very low the KF92 is amazing. A few users in my free discord own the KF92, maybe you can hop in there and get some feedback from real owners :)
Different strokes for different folks. I got TWO REL T/5x Subs for $1050 TOTAL,on sale before the price increases. Small-medium room. My system is music priority and the subs just fill out my frequency range incredibly. You would never know they were there…NO window rattling ever needed or wanted…even if I am watching a movie! 😎😂👍🏼 The KEF does look like another masterful piece of engineering, though! COOL STUFF NEMO!
Hey Bob!! The T5X pair really is a killer setup, sometimes I wish I still had them here. The KF92 is going to be more for someone who wants that theater style room rumble generally associated with larger subs but in a compact package where the T5X is more about maximum SQ & integration and it's damn good at it.
That sub kicks ass. Best I ever owned for sure. End game sub - I don’t need anything more. And single sub does it for me vs previously had always double.
happy to help :) KF92 should have a pretty high WAF, if you need something smaller the KC62 is great also and then there is a the SVS Micro that also should have a super high WAF.
Great reviews Nemo, thanks for your channel and work. I appreciate your critical thinking abilities and rationale perspective when I heard you and spare change talking together on a longer video. Thank you for reviewing this KF92 and reassuring me that a man of your experience with many subwoofers approves. I was looking for reviews of the KF92 when I had a chance to buy one a short time ago on special sale and wasn’t sure what to do. There were some positive ones but not enough or comparisons to other subs. I took the plunge based on the KC62 reviews, hoping similar ability but for larger spaces, and I was happy I did. This KF92 feels like it goes very low from what I can tell and is both musical and great for home theatre punch. I had a klipsch R12sw which was decent but this one just is more controlled and powerful and low. My step father has dual vandersteen subwoofers and this one definitely sounds deeper and can rumble for sure as well as his setup, albeit he prefers his not as loud so it’s not cranked up. But I mean KF92 seems capable musically and with home theatre. I wish I could have obtained an svs sb16 to compare, as that seems to be one of the best regarded, but spare change’s review suggested this KF92 can be comparable, so even if not better, if it is close to that as a standard then I think I’ve got the subwoofer I need to complete my klipsch RP series atmos system. Now I just enjoy my system and don’t second guess my sub.
The SB16 is a different monster entirely, where that'll shine is in larger rooms or when more output is demanded. Being so much larger it will be able to play low frequencies at sustained peaks at much higher volumes but it's around 3x the size and weighs over 100lbs!
Great Review! How do you think the KF92's would do in a larger room? Like a 17.5 ft W x 22 ft L x 8 ft H room (it has a 9 ft wide opening leading to another room)? Would two KF92's do the trick or go with a larger pair of subs? Usage would be 30% music / 70% movie and gaming.
I have a room about the same size, even 1 KF92 has enough output. I will be getting a 2nd soon though. When you see the sub you'll say nooo there's no way this little sub will fill my room with bass, but it does!
When I first heard the KF92 I said this sounds great for the size. Then I put movies on like Fury and felt my room rumble from the tanks and was like wow this sounds good period! I demo'd one in my room before but now I'm trying to purchase a pair.
My mates parents had a pair of Kef referance 8s with the twi uniQ driver and a pair of dual opposed eight inch bass drivers mounted vertically in the cabinets, they blew me away and set me along the hifi path. 11hz, dam man that is low for such a small and sealed box I have however had the pleasure of borrowing a Sunfire True signiture model that has twin 10s and 2400 watts and that did not go down that far, truly impressed.
@@NemoPropaganda Very true, this one had the mic and DSP room correction so was not all that bad and oh it was in a very small room and it was loud as funk. Impressed you know about them, kudos brother.
Awesome review. I am just don't know why not many review about KEF sub, as I know KEF make a very good sub. I also owned a pair of KC62 and also owned a few other KEF subs like 10B and 12B
@@NemoPropaganda I think for the price KEF 10B dan 12B is pretty good. But for the speed for sure not as fast as KC62. But the 10B and 12B have lower extension when you play louder, as KC62 losing its low extension when you play louder.
drive.google.com/file/d/1s9a1sz48U6J44TLd7ZQIR6OmTVeiLQ6w/view?usp=drivesdk this is the REW measurement ini my room. The blue line are 2 JL E112 on each rear corner and 2 SVS SB3000 in each front corner and time align using minidsp. The orange line are 2 KEF 10B on top of each JL E112 and 2 KEF 12B on top of each SVS SB3000 also time align using minidsp. Look at the graph, the FR in my room the KEF actually beat JL and SVS , the KEFs can go all the way to 9Hz. no EQ applied to all of the subs. My room size around 3000 cubic feet.
I set up my first new system for 25 years and decided on a pair of Kef LS50 meta speakers powered by the new Bluesound Powernode streaming integrated amplifies and wanted the KC62 sub woofer as Darko has said it was amazing. It was during Covid and because of demand it was on a long lead time but was offered the KF92 discounted. I bought it and have not regretted it. I am 100% music at the moment and was very impressed. I set the cross over at 50hz on the Powernode and the base on some tracks is awesome. I am considering upgrading with the new Buchardt 400mk2 and possibly their amplifier. Ive just started to save.
Nice! The LS50 Meta are great! I'd probably upgrade the amp and keep the speakers as they're very good and S400 MKII is different but not better per se. To my ears it's better but I love the sound :)
Absolutely agreed, keep the speakers... the LS50s truly respond well with higher capability amplification. I'd build around the LS50 platform, continuing to optimize in other areas little by little, ie., room acoustics etc. Those Kefs are so well executed, that when set up right, supplemented with a well tuned sub system ... in an adequate room, you've essentially got state of the art point-source playback. An imaging, soundstaging, experience machine!
I have enjoyed your subwoofer reviews including the KEF KF92. I upgraded my 23 year old Paradigm home theatre system to the KEF R11, R2c and 3 pairs of Ci200R-THX speakers for Atmos and rear surround. I did keep my old Paradigm PS-1000, 250 Watt subwoofer. As I have not compared anything else in house it does sound alright. We use it for movies and music, about 80/20. I was considering replacing the sub with with one KF92. Without auditioning the sub could you make a prediction on how much improvement I would hear and where it provides the biggest change. Thanks for your help, Michael
Michael, it's like as if you've been driving the same Toyota Camry since 1998, she's been good to you over the years and is a great car, no reliability issues, and the ac still blows cold. But then you pull up to an Audi dealership and test drive the new A6, it's a night and day difference, your 1998 Camry isn't a bad car, it never was. The newer Audi A6 is still superior in every way you. It's kind of like that.
Did you feel you had to get the volume at high levels to achieve that extension you mentioned? How does it perform for low to moderate level listeners?
Hi Nemo, love your reviews. Question how would you characterize the sound of the sub, meaning JL Audio subs, bw, and rel ht series are dry and Rel TX is warmer or wet. Where does this fall? Hope question makes sense
hey Weiss, so it's gonna play cleaner and lower for sure but personal taste may play a factor here. SVS gives you that bass that's on the dominant side (spl style) where KEF is more in the middle of SPL & SQ style subs so the KEF is cleaner with it's presentation and certainly does extend lower. I consider it an upgrade for those with compact spaces. The cool thing is KEF is fairly popular so you should be able to demo one in most major cities.
@@NemoPropaganda Thanks for your response. Have you ever heard a Swarm application? Four 8-10" subwoofers one in each corner. I'm thinking of the 10s for $400 hooked up with their wireless transmitters. $1,600 for four might sound incredible? I have never heard it.
Great review as always Nemo! Any idea when you are going to get the G22's in (as mentioned in a previous Rythmik video)? I want to pull the trigger on a sub but I feel like I need your input on that one first.
I have the G22 already, if you're in the discord (which is free) I usually post early impressions there, you can also ask there for early impressions on anything that has not been covered yet and I will share them if I have them.
What sub would you prefer for bass in movies? 2x Kef KF92 or 2x Rel HT1205 mk2 ? Already got 2x Rel S/510 for music by high level but looking for pure LFE use.
you want more watery rumble ultra low frequency go for the KF92, it's an absolute monster in terms of extension. If you want more tactile, precise bass go for the 1205v2, it doesn't get as low but still has great extension and you'd save a ton of money. Either options is fantastic in my book!
Hey Nemo, thanks for all your reviews! The listening area is 20x13 all though it extends being an open concept living room to about 20x25. Will this KF92 be sufficient for movies 70% Music 30%
I'd say start with one, if you need a second one that could be a goal for next year maybe. How much bass is "enough" is a tough question to answer, listening habits and personal taste vary greatly and open room concepts can be challenging. A few guys in my free discord own the KF92 so maybe hop in and ask their opinion.
Regarding 100% music system. Irrelevant of room size. When it comes to speed articulation detail etc would you say the KF92 is REALLY the equal of KC62 ? If you give KC62 say 95/100 in those areas what would you give KF92 ?
@@Natan9000 sorry brother, I meant to say cubic feet, bass fills the volume of the room. You can google audioholics room size rating and you'll find their article.
Would you say this is comparable to the SVS sb3000? I know the 3000 is larger, but with the little bit extra power of the kef thought they may be somewhat similar 🤷🏼♂️
Funny you should ask because 2 9" drivers like the ones found on the KF92 does equal a single 13" driver so the comparison is fair with respect to cone surface area and they have similar power at 1000w and 800w respectively and both are compact. Unfortunately I couldn't really say which one could play louder as I don't test max SPL. The double the price KF92 does take an easy win for low end extension and overall sound however.
Nemo, question on placement and if getting 2 of them... With their drivers on the left and right instead of facing into the room as is with traditional subs my concern is I have a console that houses my equipment so these would have one woofer hitting the side room walls and the other into the console 3 feet away on either side. If I turn them facing into the room then one sub is facing the back wall. Can you elaborate on what your experience with placement was compared to "regular" front firing subs in your room? Thx ✊🏽
Hey ben, I tested that a lot with both KF92 and KC62 and I didn't find anything conclusive. They seemed to sound great regardless of how I had them faced in my room. There was slight phase shifts as I rotated them of course but that is to be expected and every room will react differently to that.
I know this is an old reply but when I had the KF92 I tried it with the drivers facing the sides and with them front to back and I much preferred the way KEF designed it with the drivers on the left and right.
Love the depth of the review! I have a 18' x 14' x 8' ceilings. Thinking about getting two of these. Would that be enough for low extension? Thanks broski!
oh yeah! one will extend like crazy too, it's just about how loud do you want it, if you really are considering this sub I suggest you hop in my free discord as there are a few users who already own them so you can get some real world feedback from owners. Link is in the description.
My opinion is pretty simple, the E15 is the more capable, if you can fit it, go for it! With the KF92 a good chunk of your money & value is going towards that smaller form factor. If you don't need or care for that small form factor the E15 is an easy choice. I have only heard F18 in a theater setting so cannot really comment too much on its musical prowess but I'm sure it's class leading for a woofer it's size.
These are discontinued and on sale in Canada around $2000. My room is large 13x40 8' ceiling. Primary use is 2.1 for music. The listening area is about halfwayI currently have def tech sc4000. Ilistened to a REL t9x and loved it at low - med volume good recordings. But when listening to metal from the 80s and 90s I couldn't get enough output from of it. A rhythmik f12se delivered to the border is about $1800 Canadian. My speakers are kef r3. How would you compare the 3 for music? For waf less than 16" cubed and looks are factors
if you liked the T9X and need more output I'd suggest a single F12SE, a single REL S510, or a pair of T9X. The KF92 is an outstanding subwoofer but its main strength is its ability to deliver strong low end reinforcement in an extremely compact form factor. The KF92 is more at home in a small to medium theater where extremely deep extension from a small subwoofer is needed.
@NemoPropaganda thank you. Very fast reply. Yes for the WAF I think it needs to be a single sub, so probably the f12se based on mostly your info and specs. Ps. I just subscribed. My first ever
Hope you're still checking these comments. Got a question. I'm considering this sub for my home theatre setup. It's a medium-small room (it doubles as my bedroom lol). I saw people saying to buy two even with that room size...but I sit very close to my TV and speakers (5-7 feet). Will 1 of these subs be enough to enjoy that below 20hz subbass? I do 50% movie and 50% music.
When people say below 20hz usualy they mean below 30hz. Below 20hz is infrasonic and if you want to notice infrasonics at substantial output you generally need something like a pair of 18" drivers. That being said the KF92 is the lowest extending sub I know of given its phsycial size. I don't think you can do better. If you don't listen too loud you might be better off with a pair of KC62 but either option gives crazy low extension for how small they are.
@@NemoPropaganda Thanks for the info! I'll try with just one and pray that it will be fine because it will be placed so close to my listening position. If I feel like I need two, I'll get a 2nd one on the used market. If I get lucky on the used price, i'll end up spending about the same as two new kc62s ;) But yeah, my listening levels aren't that loud because I sit so close to my speakers and TV.
Thanks@@NemoPropaganda! One more question - If you were give the choice between 1 KF92 or 2 KC62s, which would you pick? Assuming room coverage was not an issue.
@@NemoPropaganda its not the case. I have both here and the kube 12b has exact the same fq response in room. But the kube 12b can mantain it at higher volume where the kf92 reach suprosingly faster its limit. I did some rew messuremnts to prove it. The kube 12b is realy a monster and that with suchh a low price
oh man I wouldn't even know how to answer that question, 4x KF92 is not something I have experience with and that's $8000 worth of subs. Only thing I know is it would sound amazing but couldn't even begin to guess how it would compare to 2x E15.
"Mussst resist the urge to buy." Dammit sir I've already purchased a kef kc62 and recently a rythmik e15hp2(love them both btw) what more do you want from me!!!🤩
@@NemoPropaganda Believe it or not they play well together(up to a certain point of course). I have the Kef sitting on top of the Rythmik kind of like Masterblaster from Mad Max. Seriously though love the reviews I really want a kf92 now but between the two beasts that I have now I think I'm good.👍
Hi Nemo, how would you compare the KF92 and the Rythmik F12SE if one or the other was to be used in a music only system? Thanks for your help and all the great reviews! J
F12SE will play louder, better note to note distinction, and better midbass. F12SE is the more articulate subwoofer, the KEF is smaller by a good amount yet extends like crazy, it’s SQ doesn’t match Rythmik but its still very good. Just to be clear F12 also extends very low.
@@NemoPropaganda Thank you for that! Would you say the KC62 has better articulation and note to note distinction? I'm mainly concerned about high quality music reproduction. I don't listen to a lot of electronic music. My (large) monitors taper off below 65, even though they are like -13 dB at 38 Hz. Thanks!
Thanks for the great vids. I have a Naim Uniti Atom and a pair of Tekton Lore Reference speakers. I currently have a Klipsch Cinema 600 sound bar which comes with a 10 inch sub, I think rated to 28hz. Do you think adding the KF92 to the Tektons would be good? Room isn't huge.
the KF92 is an extension monster! If you're looking to take that 37hz down into the teens the KF92 will do it. If this is for theater you'll love it. Now if its a music only system and you don't listen too loud you might be able to get away with the smaller KC62 but everyone I know who owns the KF92 absolutely loves it.
@@NemoPropaganda pretty close to pulling the trigger on this. I'm mostly looking to get more detail from movies than I've been hearing from my sound bar system. Extension and clarity/definition over volume/pressurization. Anything from Rhythmik you'd recommend over this for the price? They seem to have high bang for buck. Thanks!
If I have kef speakers is it easier to pair them with lets say kc62 or kf92 cause they are the same company or is rythmik f12se also very easy to pair with kef speakers? I know that rythmik is better sub generaly but seamlesly pairing is what I want to know which would be better choice? Cheers
Great then i'm more into rhytmik:) in other video I asked you about subs maybe you didn't see it. The sub that you reviewed Rel s510 is it comparable to Rhytmik F12 SE or if its better how much is it better what are the differences. I didn't hear non of those two so if you could describe it to make a better picture of the differences between those two. I'm a music producer so I need a sub for music..
Great review as usual. Tnx for that, but now you have made my task even more difficult. I have all system from kef. Kef r700 fronts, kef surrounds, atmos etc.. So I decide go for KF92, but now came out new rel ht/1510 predator.. Same price range, same rms + - . just the size difference I have fairly large open plan living room ( +/-50 m2 ). I'm listening more house music and movies so it would be good if he went down to 20 hz and less What would be your recommendation between these two?
Thanks for your reviews. Any thoughts on KF92 vs Rythmik L12 (or pair of L12's), for mix of HT and Music? For a 200-ish sq ft room, size and aesthetic are factors.
before I advise may I ask, if you have KF92 money and aesthetics are a factor why is the L12 part of the discussion? It's fairly simple/ugly compared to the KF92 and Rythmiks F12SE is far more beautiful so shall we discuss KF92 vs F12SE instead? Or is there some reason the F12SE is not an option for you? lmk!
Part ignorance (so appreciate your reviews). But the F12 is an option, budget wise. Part was shying away from large size and weight, aesthetically and after lugging a 70 lb sub around a number of moves over the years, and likely more moves to come, And class D with dual voltage also good to have if move abroad. But it is an option, if sound-wise materialy better Also wasn't sure if two subs or a dual fired sub would be better for sound through the room, as not a dedicated theater room and doors often open into other rooms. From your answer, you like the F12 for that budget, it sounds like?
@@pushkin168 okay, back to L12 vs KF92 then, both are fantastic but the L12 isn't winning any awards in the looks department, it's a very utilitarian look with a vinyl finished cabinet. It will have much better midbass than the KF92 and more consistent low frequency extension. The KF92 is of course much more beautiful, can extend much lower but there is a caveat here, the KF92 uses an active DSP, as you demand more volume from it the bass extension will be reduced and at say 100dB it will not have the extension that the L12 can produce. With that said if you're looking for the smallest sub with the deepest frequency extension and you will not push the sub too loud then the KF92 is without equal but if you're hunting for 100+dB output and low frequency extension at the same time the L12 may be preferred. TLDR the KF92 is an excellent LFE sub for those with smaller to medium spaces who want to recreate a movie theater environment albeit at much lower volumes.
Nice review and onto an entirely different topic. I'm curious about that crazy cool looking sofa setup in the "soundbar living room". Do you happen to recall the manufacturer and make ? Love the design aesthetic and it looks incredibly comfy for modern styled furniture.
Hey brother thank you so much, I just bought it a few months ago and absolutely love it!!! It's the Diego Sectional available through Scandinavian Designs. Price is a bit high but it's made in Italy and the fabric is high quality and easy to spot clean when needed. It replaced a Lumin I had (from CB2) which didn't live up to expectations and was really hard on my back. The Diego certainly is very comfortable and very supportive. I still use a pillow for my lower back but I have an extreme arch and always need extra support.
Comparing to a Rel T7x isn't a fair fight. Price and sizewise, comparison would be more relevant against REL T9x. I'd love to see a review of the Dynaudio 18S / Sub6 against this too.
T9X would have the same outcome. Dynaudio subs…. Meh… i had a pair of the sub6 but they had some issues and could not be reviewed. I lost interest after that.
@@MRPC5 I tried bro, I bought a pair of Sub6 on the used market for review, both of them didn't work. It was very odd. The seller was very adamant that they worked prior to the sale.
Both are very good subwoofers. If you're more concerned with max output go for the 1961, if you are more concerned with maximum extension the KF92 is impossible to beat for its size but it is more that double the price. If you can afford the KF92 but want to play louder then go for the 1723 1S. It will extend lower than the 1961 and sound much cleaner all while having serious output potential.
@@CsRajkai You are describing 1723 1S. I think that is what you will be most happy with. KF92 is really great but the biggest benifit is crazy strong extension in a small package, especially at lower volumes. 1961 is great all around sub but 1723 is more what you are describing.
The KF92 is always going to come down to this: if it's output is sufficient for the room it's hard to find a better theater sub regardless of the size. If the output is not sufficient then generally speaking nearly anything larger will be preferable. The E15hp2 is substantially larger and will have considerably more headroom at all frequencies as well as a larger sense of scale. As far as musical performance I like the KC62 better than the KF92 but the E15hp2 is better than both. Very few brands have the fidelity of Rythmik.
@Nemo Propaganda Thanks for the reply. I currently have the Klipsch RP-280FAs and 2 R-115SWs in the front, and it's pretty tight sandwiched between the front walls. I have a little bit of room to toe in the fronts, but not enough to get them perfectly toed into the center. The KEF R7's bases are 2" wider than the RP-280FAs, so if I used equally wide subs, the problem would only be worse. The E15 is 2.5" more narrow than the R-115SW, so that will be about equal out to my current setup, but the extra room provided by the smaller KF92 would be nice. And the aesthetics would match a bit better with the R speakers. I can get the E15HP2 in gloss black for $1789 shipped and found some open box deals on the KF92 for a little bit less than that, so the price is irrelevant. I'm also in a condo with a sensitive neighbor, so total output isn't a big factor either. Pretty torn, because I know the E15 is the better sub, but it's a lot bigger and heavier, which might not be worth it. Oh, also, I live on the third floor with stairs, so that sounds like a pain.
@@Dasbeerboots based on everything you've said I think you are a perfect KF92 customer. What you're trying to accomplish is exactly what its designed for.
Speaking of high level outputs, I have a 1200W Definitive SuperCube II. It is connected to an AudioLab DAC as a preamp outputting via low level to the sub, and balanced output to Adam active speakers. Do you think it would be a good idea to take a digital output from the DAC to an integrated amp so that I can get high level output to the sub. I have a Sonos gen 3 wireless sub that has 2 opposing woofers like the KEF. It is the only silent woofer I have ever owned. I am guessing the KEFs have a similar property.
Generally speaking there is no inherent benefit to using highlevel unless your suboutput is crappy then highlevel will be a cleaner output signal. Only way to know is to try.
Ah yes indeed, the two subwoofers on paper will seem very similar to the average consumer. The difference should be easy enough to resolve with a demo though :)
@@NemoPropaganda What if you cannot get a demo? Would you base your recommendation between the KC62 and KF92 on room size, content or what you are pairing them with?
@@andrewdorolek5948 KC62 is an easy choice for stereo or small room lower volume theater while KF92 is better for larger room or louder outputs both are extremely good and sound very similar, easy way to look at it is the larger KF92 has more output.
In the past I would have laughed at someone for having a Heavy thing problem but once you have to carry those things up a tight curved stairs by yourself or even with two people you will want to throw that sh** away hahaha. 45 minutes of struggle, smashing your finger, getting bruised, almost having it slip on your toe or on your whole body will make you never want to have anything heavier than you are capable carrying alone Sounds like a great Sub. To bad that it's out of my price range but I'll keep it noted for the future.
Hey what's up dude! The 1961 1s is narrower for sure but I think it's overall size is similar if not maybe a little bit bigger so I would expect it to be able to play a bit louder at the limit and it can still extend plenty low but not as low as the KF92. Both are really good subwoofers, the KEF is all about as much extension out of a tiny box where the Arendal is more so just a great subwoofer overall and it's major feature is the narrow design. If you don't need a small subwoofer like the KF92 for sure you will have tons more performance from something larger like the 1723 1S and you can of course buy 2 1961 1s for the price of 1 KF92 so a lot of the money you're spending on the KF92 is to have maximum extension while taking up very little space. For some people who have limited space it's an easy decision but if you have lots of space the big value of the KF92 may be less important to you. Hope that helps put things in perspective.
@@NemoPropaganda Thanks,actually I have a place limition the only problem that I have with the kf92 is that it is "firing" for both sides and the spot that I have for it is blocked on the left side, only 5-15 centimeters. On the other hand the Rendal output is from rhe right side.
@@NemoPropaganda good review, as an an owner of Arendal 1723 1s it good to hear, that sub is really big, it dosen’t sound as it looks, sounds never overpowring the speakers, very controlled bass, it works good even if you room is not massive, i never been able to make that sub sweat in my room, even on louder levels 80-85 db Thinking on adding another in future
Hi, I have a HT room that's 20ft x 14ft x 7ft After seeing this review, I am looking into one of these subs - either 1 KEF KF92 OR dual Rythmik FVX12s (basically around the same cost). My main speakers go pretty low - they have a FR from 20 hz (the speakers have a built-in powered sub), but probably start rolling off around 40 hz, so I would need a sub that does well from 40-45hz down and is solely for HT. Any thoughts on this?
Dual FVX12 would have A LOT more in them overall vs a single KF92. The pair of FVX12 would extend almost as low and play much much louder and with outstanding SQ. If you want a single the E15HP2 will extend just as low as the KF92 but play much louder but of course both these options are much larger and the whole point of the KF92 is extension of a huge sub in a small package. If you don't need the small package the larger Rythmiks will offer up a ton more return for your dollar.
Is the KF92 one of the premiere options for a 50% Movies 50% Music setup? The only issue I have is that I have a very large space (open floor plan great room) even if the audio setup is isolated to about 1/3rd of it. The sub needs to be relatively compact for WAF reasons, so no bigger than 12" I think in terms of footprint. Dual subs should be possible down the line. For reference, the living room area is about 15'x19' with 10' ceilings and the left side opens up to the dining room and kitchen and extends another 30' or so.
Hi Reinku, KF92 remains one of my higest recommendations for mixed systems where compact enclosures are required, of course I understand the concern for output also. It's hard to say if it will be enough bass or not because everyone has different taste for how much bass they want. Sometimes we just have to try it, if it doesn't work out you can always add a second one or return it for a larger option. Conversly the JL E110 should offer up more output in a similar sized enclosure and is also an excellent choice but a little more expensive.
@@NemoPropaganda Thank you for the quick response! I'll take a look at the JL E110. The subs I've been considering are the SB-3000, Rythmik F12SE, and KF92 so far. It's been very difficult trying to figure out which one I'd like to give my first shot to. I was pretty ready to go for the F12SE but your review gave me pause since I felt it might be slightly lacking for the HT side of things.
@@reiniku5830 F12SE is a lot bigger than KF92 but if you can fit F12SE that would get my vote easily. The real value of the KF92 is for those that really need a compact yet powerful solution for aesthetics or physical limitation.
@@NemoPropaganda I think I can just barely fit it. How do you think it'll perform for HT? I think I'm ready to audition it and see if it will work for both my music and HT needs.
@@reiniku5830 The F12SE? Extremely well!! It's a very capable 12" for music and movies. Easily one of the best, I still own mine and love it. If you lived close I'd say come listen.
Hey i asked about REL HT/1205 MKII in one of your videos and i told you that i sold SB 1000 pro, i wonder maybe i should get KEF 62? remember my room is 4.3m lenght 2.6m wide and 2.55m high. Mostly i listen music but i am basshead kinda. I would never guess that sub of that size i mean KEF can go so low and have 1000w power DAMN !! i wonder how it would play in my room. Main speakers are KEF q100. (a little bass they have and dont go audibly below 55hz ?)
my sold sb 1000 pro was under desk on my left (when i listed i take chair back, desk is open), if u put here 1205 mk II well it could be tight xd i wonder how the sound diffrience is for room of that size KEF is 1,480 dollars here, mk ii is 1177,99 dolars@@NemoPropaganda
KEF would be noticeable "weaker" than rel? sb 1000 pro 70% max power was more than enought for this room :D u know i am bass head but not psycho as u said in rel vid i dont need 2x 15" subs xD but i like the authority, slam etc@@NemoPropaganda
those are 2 really different subs my bro, the JL E112 is a good bit more expensive and possibly the loudest sub you can buy in that small a cabinet. JL is all about extreme output out of a compact enclosure while the KF92 is all about extreme extension out of a compact enclosure. The value of the KF92 is having as much extension as possible out of an incredibly small cabinet for those who don't need too much output. Both subs can play loud and get low but the JL gets way louder and KF92 gets a lot lower (albeit at lower volumes). At louder volumes the JL E112 can do everything the KF92 can do and more. As far as sound quality goes, the JL takes the edge also, it's a serious beast of a subwoofer and worth every penny more it costs. For the record a more fair comparison would be the E110 but the result would be similar.
Yes love to see a real battle head to head with 510 & 92 seperated review in music and movies. Real killer will be a review first singels then duel fight 🥰🥁🥁✅💥
Seems to tick all the boxes for me, but for mostly music, is one of these enough in an 18’ x 23’ room? (Approx 3,330ft3). Until I could add a second one at least…
that's a tough question to answer my friend, how much bass is enough is like asking how much salt on french fries is enough, everyone has different taste. I would consider your room to be sized Large and I think 2 would be ideal. Most people should be happy with 1 but some people have very extreme taste for bass.
@@NemoPropaganda thanks, I don’t need to shake the room at 90dB+. I plan on having dual subs, but if they’re higher end ones like this I’ll have to live with one for some time before adding a second one, unless one is satisfying.
@@gustoaudio8711 one could be satisfying, one was more than I'd ever need in my room but I have a smaller room. I think you gotta just try it and have the experience.
@@NemoPropaganda I have a hunch 2x Rel T/9x is what would suit me most for the easiest system and room integration with enough quality and power, but then the price casts serious doubts when you look around. I’m not sure one would cut it and I’d have to live with one for some significant time at that price. For a few hundred more than a single T/9x I could get dual SVS SV2000 Pro’s or dual 3000 Micros. And for the price of dual T/9x’s I could have an SB16 Ultra with change to spare, or a Rel S812 for only €10 more… not to mention dual SB3000 for over €500 less. So it becomes one of the most difficult decisions I’ve come across in hifi, but maybe I’m overthinking it - physical size is a major factor in the decision though which is why I’m so interested in the Kef. Regards the KF92, it’s only about €150 less than an SB4000 which no doubt would do the job on its own, I’m not quite sure how a single KF92 would compete in this size room.
@@gustoaudio8711 Hey Gusto, you are cross shopping brands that should not be cross shopped as they are totallly opposite sounds of bass, I made this short video to help explain the difference: ua-cam.com/video/rEz03XkcslI/v-deo.htmlsi=AKPphGTJUvV9motY
Between this and the REL T9x or S/510 for music only which one would you get? thing is I'm getting a deal on the S510 and this KF92 but can't decide. a demo is not possible either. I do have personal experience with the T7x though as I own that one but want to upgrade. thank you. I listen to all genres but mostly rock, trance, symphony, acoustic, pop.
I have not heard the s510. The real strength of the KF92 is in mixed systems where this tiny sub can belt out crazy low end extension for a real theater experience yet is also great with music but if you're only going to be listening to music then a lot of the value of the KF92 isn't going to be used so it's better to get the T9X. Think of it like this, the strength of the T9X is in that 30hz and up region where music is, the strength of the KF92 is 30hz and below where most low freq effects are so music only, go for T9X, more theater focused, go for KF92.
@@NemoPropaganda Thank you!! Unfortunately, my problem is that I can't listen to it and I have nothing to compare it to because it's quite expensive .. but I was afraid it was like the svs.. Small volume and can't give sound pressure... I thought maybe Rel t7 or t9 or ht 1205 and now I found this Kef 92...Music and movies about 50-50%
@@NemoPropaganda Thank you very much!!! I was just afraid if the Kef 92 can also create a small air pressure, but then surely the Kef is much better than the svs? and would the Svs sb 4000 be another alternative!?
@@tibitibi1407 If you really want to make sure you get the right sub for your room hop in the free discord bro, plenty of guys with tons of subwoofer experience that can help you.
Because the low frequency response of KC62 and KF92 is the same ( 11hz), do you think we can still hear some difference, more extension or more rattling if the room size is the same? What I mean is, because one is using 6.5" drivers and other one is using 9" drivers, can we feel any difference if we play them in the same small room and on the same volume level just because of the driver size? I already own a KC62 and planning to buy KF92 for the living room but it is not so big so I might still get away with KC62 but if driver size creates any difference, I would go for KF92 even though claim low frequency is the same for both. Thank you.
Their specs are misleading as that 11hz is only at low volume. As the volume rises so does that extension figure for the kc62. I imagine at volume the differences between the 2 subs will be readily apparent.
the difference between the two is more apparent at louder volumes as Neil C pointed out. Since you already have the 62 try it in your living room first perhaps? But yes the 92 will play it's lowest frequencies at higher volumes than it's little brother.
oh bro, 1723 1s is much larger, digs down into the teens, and plays those lower frequencies with substantially more output than the much smaller KF92. Always remember for smaller subs like the SVS Micro, KEF KF92 or KC62, etc... A lot of the money you are spending is going towards the size so if the size is not a big deal for you then for sure get something bigger like the 1723 1S.
@@NemoPropaganda Very helpful, thanks man. I'm about to do a new living room setup. Looking for a matching front stage with bookshelves and a single sub. Seems like the best options I can come up with are either a KEF setup with R3's, R2c, and a KF92 or Arendal with the 1723S bookshelves, 1723S center, and a 1723 1S. Would you recommend one of these setups over the other or something else altogether?
@@BClear91 I couldn't say as I havn't heard either of those sets of speakers. If you're in the free discord I'd ask there, maybe some of the users in there have that experience.
KEF really needs to send you a cube 10 or 12 demo unit so you can give us your honest thoughts on them. If you go by user reviews they are fantastic but you never see or hear about them.
@@NemoPropaganda Thanks! I'm starting to look for a sub to go with raidho xt-1's - very fast...audio only system - roll off at 50-60hz. Any thoughts on that coherence/blending would be #1 priority, aesthetics #2 (although I may get overruled on that)
@@bferguson001 ooo that's a big money speaker :). Okay this is actually a great question. The kings of speed are Rythmik, REL, and shockingly enough JL Audio. JL Audio's E110 being more SPL focused does it with force, it's tone is heavy (review coming soon), and aggressive. If you like heavier bass go for the JL. Rythmik's F12SE is the total opposite, it handles delicate passages better, has a better midbass region, and of course amazing transient response and bass fidelity with bass that more comes from an ink black background. If you want Audiophile bass this is the one. Lastly (and certainly not least) the REL T9X, the most beautiful of the bunch is going to be very similar to the Rythmik but with a warmer tone, less extension but slightly more bass detail. If you have not already seen this please watch ua-cam.com/video/rEz03XkcslI/v-deo.html. It will help you decide if you're more REL & Rythmik customer vs JL Audio. If you decide you are more on the REL & Rythmik side then they have totally different looks so it should be easy to choose.
Excellent review!! I am debating between KC62 and this. My room is about 25sq meters, and I listen to music around your volumes: 75-80dB, and very rare 85-90db. I don’t need window shaking bass, but I do want to hear those low notes when listening to music or movies at those volume levels. Would a KC62 be enough or should I go for the KF92? I would go for the 92, but I start to believe it’s overkill for my current room and listening levels..
@@ayokay123 bro! I'm on the board of my condo also, I hate it so much but nobody else will do it :(. I feel like a hall monitor, everyone is so stupid. I was patrolling the neighborhood one day, a guy asked what I was doing, I explained I was on the board and just making sure nobody left their trash bins out and he responded "damn they just pay you to drive around in this cool car all day?" to which I replied, NO! I don't get paid for this, and kept the "you idiot" part to myself.
@@NemoPropaganda Precisely. My building has over 300 units and it's near. impossible to get anybody to run for the board because it's such a miserable, thankless job. And yes, we also have a few idiot owners who either think we're getting paid or receiving kickbacks from vendors. Such ungrateful wretches. You bust your butt to protect the value of their hard earned asset and a simple thank-you is too much to ask for. Fortunately, we hire a management company for the day-to-day stuff. We only get two or three owners attending the monthly zoom meetings, so I guess we're doing something right. Owners only care if they think there's a possibility of a special assessment. You know all this.
Hoo-boy...got me torn between this KF92 and the Rhythmik G22 to replace an older Outlaw LFM-1 Compact 10" ported, downfiring sub. I use my system roughly 60/40 leaned towards film, and the G22 miiiight be overkill in my space, but having such "precise" capability and lower extension, even at a reduced volume (and for less $$$) seems like fun and makes it something that could be with me for the long haul, as I don't tend to collect or swap often, if I like something.
both are seriously good options but there is a substantial size difference between the two. A big chunk of what you're paying for in the KF92 is the compact form factor, if you don't value that the G22 would be the logical choice as you'd save some money while gaining more output and precision. But if you don't need the output and instead value the small size, KF92 starts to make a lot of sense. You just need to decide what you value more.
@@NemoPropaganda Thanks, that's pretty much what I'd been thinking, and I've been doing my pros/cons lists, for sure. I also came across the Goldenear SuperSub X, which seems to live in a similar space as these other two. Really makes me wish there were more places to go get some hands (and ears) on these things before purchasing!
output is how loud it can play. Bass depth can mean 1 of 2 things. Either it is referring to the low frequency extension or it is referring to a sound characteristic where the bass sounds deep when it hits, like there is good weight & decay.
SVS Micro is more comparable to the KC62 and this is a situation where the more expensive unit (KC62) is the better one. If you have the budget for it the KC62 is incredible.
@@NemoPropaganda I currently own an SVS SB-3000 mainly for music, would you consider the KF92 a large upgrade over my current sub for music? (I've actually had the chance to try a friend's kc62 and while the bass quality was great, the output was lackluster for my room)
@@RealDiGiPHiX KF92 is an upgrade in some ways like extension and how clean it plays but the SB3000 has a stronger attack to its bass and can play louder so it just depends what you value.
I pretty much understand all descriptions of subs sound quality, all that words like texture, extension, tone character and etc. But can someone describe what is authority, I'm struggling to understand what that means 🤔
mmm, it's hard to describe sound because we can't see it or touch it so maybe this sounds kind of wonky but to me authority is a combination of a big sense of scale and effortlessness at the same time almost like the subwoofer is happy and not strained at all. Kind of like accellerating in a car with a large engine, even though your foot is not all the way down you can feel the power, you know theres more of it, you're accellerating fast, and you can tell its easy for the car.
Lol'd @ "soundbar living room" 🤣 Your living room looks to be about the same size as mine, or maybe even slightly bigger. But, I've got Arendal 1723 Monitor's in mine and have had pretty large towers the likes of Revel F208's crammed in there! I was never any good at physics so I just pretend it doesn't exist 😭
You have the same kicked in area where the TV is? That's what makes it so hard to place a sub but I remember someone in the discord had dual Emotiva RS11 in a similar kick out.
from the FAQ section of my free discord: The KF92 is always going to come down to this: if it's output is sufficient for the room it's hard to find a better theater sub regardless of the size. If the output is not sufficient then generally speaking nearly anything larger will be preferable. The 1510 is substantially larger and should have considerably more headroom at all frequencies as well as a larger sense of scale. As far as musical performance I'm actually going to give a slight edge to the REL 1510 as it's leading edges are a little more well defined while the KF92 has more of a softness to its leading edges. Lastly the 1510 has a bit of a heavier tone to it while the KF92 has a slightly lighter tone by direct comparison. If KF92 is between SPL & SQ the 1510 is just a hair over towards the SPL side only due to it's heavier presentation. All other aspects of the 1510 are very SQ. Worth considering is the KF92 employs active DSP meaning as output increases frequency roll off becomes more aggressive while the REL 1510 will be more consistent at higher volumes. Both subs perform well at lower volumes so you certainly can shove a 1510 in a smaller room or a larger room where as KF92 is really for lower volumes or smaller rooms. Hope this helps.

Were you testing with 1 or 2 of these?😅
@@eyeshezzy just 1
@@NemoPropaganda amazing
@@eyeshezzy I have only 1 so far and planning to get a 2nd. This sub is a beast. It has speed because of small woofers, but can go deep like larger driver subs can. It's a jack of all trades sub.

I can't believe the engineering KEF put into this small room friendly sub. I'm also glad to hear that it's a very good music sub too as my system is 50/50.
Love this little guy.

I have 2 of these paired with my Kef R11’s and yes they are good with movies. With 2 channel they sound incredible
Sounds like a killer setup!

hey thank you brother!! Indeed, KEF does some amazing things!!
@@NemoPropaganda Hi!! Your videos are very good! I have a question that you always use 2 subs!! How good is the pairing if I put a Rel T9i next to a Kef 92 as a second sub? Thank you
@@tibitibi1407 I don't think it is a good idea to mix subwoofer brands unless their design is very similar. Here you have 1 dual opposed sealed sub with DSP and another fully analog sub without dsp. I would not mix these 2 at the same time personally. I generally think mixing within the same brand is okay even if the size is different but mixing other brands together can be very hit or miss and is usually a miss. Instead sell one and get a pair that matches. The results will be much better for the money spent :)
@@NemoPropaganda Thank you very much for your help...I would like a Kef 92 first, then later I will need a second one..Do you have a good opinion of the Kef 92 subwoofer? Film and music 50-50%!! thank you
@@tibitibi1407 yes I love it, if you need a compact solution that can extend very low the KF92 is amazing. A few users in my free discord own the KF92, maybe you can hop in there and get some feedback from real owners :)
Love my KC62. Have it hooked up to a pair of LS50 Wireless. I can only imaging how great that one sounds. Thanks for a great review Nemo.
thank's MMD! The KC62 is an engineering marvel, I still think about getting a second one sometimes but I have too many subs lol.
Different strokes for different folks. I got TWO REL T/5x Subs for $1050 TOTAL,on sale before the price increases. Small-medium room. My system is music priority and the subs just fill out my frequency range incredibly. You would never know they were there…NO window rattling ever needed or wanted…even if I am watching a movie! 😎😂👍🏼 The KEF does look like another masterful piece of engineering, though! COOL STUFF NEMO!
Hey Bob!! The T5X pair really is a killer setup, sometimes I wish I still had them here. The KF92 is going to be more for someone who wants that theater style room rumble generally associated with larger subs but in a compact package where the T5X is more about maximum SQ & integration and it's damn good at it.
That sub kicks ass. Best I ever owned for sure. End game sub - I don’t need anything more. And single sub does it for me vs previously had always double.
Totally agree! This really can be end game for a lot of people.
Really thorough review Nemo - thanks again for your time and impressions. This review helps steer me, now onto the WAF 😁
happy to help :) KF92 should have a pretty high WAF, if you need something smaller the KC62 is great also and then there is a the SVS Micro that also should have a super high WAF.
Great reviews Nemo, thanks for your channel and work. I appreciate your critical thinking abilities and rationale perspective when I heard you and spare change talking together on a longer video.
Thank you for reviewing this KF92 and reassuring me that a man of your experience with many subwoofers approves. I was looking for reviews of the KF92 when I had a chance to buy one a short time ago on special sale and wasn’t sure what to do. There were some positive ones but not enough or comparisons to other subs. I took the plunge based on the KC62 reviews, hoping similar ability but for larger spaces, and I was happy I did. This KF92 feels like it goes very low from what I can tell and is both musical and great for home theatre punch. I had a klipsch R12sw which was decent but this one just is more controlled and powerful and low. My step father has dual vandersteen subwoofers and this one definitely sounds deeper and can rumble for sure as well as his setup, albeit he prefers his not as loud so it’s not cranked up. But I mean KF92 seems capable musically and with home theatre. I wish I could have obtained an svs sb16 to compare, as that seems to be one of the best regarded, but spare change’s review suggested this KF92 can be comparable, so even if not better, if it is close to that as a standard then I think I’ve got the subwoofer I need to complete my klipsch RP series atmos system. Now I just enjoy my system and don’t second guess my sub.
The SB16 is a different monster entirely, where that'll shine is in larger rooms or when more output is demanded. Being so much larger it will be able to play low frequencies at sustained peaks at much higher volumes but it's around 3x the size and weighs over 100lbs!
Great Review! How do you think the KF92's would do in a larger room? Like a 17.5 ft W x 22 ft L x 8 ft H room (it has a 9 ft wide opening leading to another room)? Would two KF92's do the trick or go with a larger pair of subs? Usage would be 30% music / 70% movie and gaming.
I think that would sound great!
I have a room about the same size, even 1 KF92 has enough output. I will be getting a 2nd soon though. When you see the sub you'll say nooo there's no way this little sub will fill my room with bass, but it does!
When I first heard the KF92 I said this sounds great for the size. Then I put movies on like Fury and felt my room rumble from the tanks and was like wow this sounds good period! I demo'd one in my room before but now I'm trying to purchase a pair.
You had issues with room modes and one wasn't working so you held off for two?
My mates parents had a pair of Kef referance 8s with the twi uniQ driver and a pair of dual opposed eight inch bass drivers mounted vertically in the cabinets, they blew me away and set me along the hifi path. 11hz, dam man that is low for such a small and sealed box I have however had the pleasure of borrowing a Sunfire True signiture model that has twin 10s and 2400 watts and that did not go down that far, truly impressed.
ah, sunfire is old stuff, i wouldn't recommend it, made in era when nobody knew what good bass was...
@@NemoPropaganda Very true, this one had the mic and DSP room correction so was not all that bad and oh it was in a very small room and it was loud as funk. Impressed you know about them, kudos brother.
Awesome review. I am just don't know why not many review about KEF sub, as I know KEF make a very good sub. I also owned a pair of KC62 and also owned a few other KEF subs like 10B and 12B
how are the 10 & 12B? Do they have similar sound to KC62?
@@NemoPropaganda I think for the price KEF 10B dan 12B is pretty good. But for the speed for sure not as fast as KC62. But the 10B and 12B have lower extension when you play louder, as KC62 losing its low extension when you play louder.

Great review of a great little sub. I finally found Nemo. Tell Dory I said hi.
Really loving the mood lighting lately. This one was a little dark but great shimmering blue.
waaaa? this was one of the brighter ones :)
I set up my first new system for 25 years and decided on a pair of Kef LS50 meta speakers powered by the new Bluesound Powernode streaming integrated amplifies and wanted the KC62 sub woofer as Darko has said it was amazing. It was during Covid and because of demand it was on a long lead time but was offered the KF92 discounted. I bought it and have not regretted it. I am 100% music at the moment and was very impressed. I set the cross over at 50hz on the Powernode and the base on some tracks is awesome. I am considering upgrading with the new Buchardt 400mk2 and possibly their amplifier. Ive just started to save.
Nice! The LS50 Meta are great! I'd probably upgrade the amp and keep the speakers as they're very good and S400 MKII is different but not better per se. To my ears it's better but I love the sound :)
Absolutely agreed, keep the speakers... the LS50s truly respond well with higher capability amplification.
I'd build around the LS50 platform, continuing to optimize in other areas little by little, ie., room acoustics etc.
Those Kefs are so well executed, that when set up right, supplemented with a well tuned sub system ... in an adequate room, you've essentially got state of the art point-source playback.
An imaging, soundstaging, experience machine!
A future sub for me maybe. Too expensive for my wallet right now but it’s some great British engineering for sure.
I have enjoyed your subwoofer reviews including the KEF KF92. I upgraded my 23 year old Paradigm home theatre system to the KEF R11, R2c and 3 pairs of Ci200R-THX speakers for Atmos and rear surround. I did keep my old Paradigm PS-1000, 250 Watt subwoofer. As I have not compared anything else in house it does sound alright. We use it for movies and music, about 80/20. I was considering replacing the sub with with one KF92. Without auditioning the sub could you make a prediction on how much improvement I would hear and where it provides the biggest change. Thanks for your help, Michael
Michael, it's like as if you've been driving the same Toyota Camry since 1998, she's been good to you over the years and is a great car, no reliability issues, and the ac still blows cold. But then you pull up to an Audi dealership and test drive the new A6, it's a night and day difference, your 1998 Camry isn't a bad car, it never was. The newer Audi A6 is still superior in every way you. It's kind of like that.
Did you feel you had to get the volume at high levels to achieve that extension you mentioned? How does it perform for low to moderate level listeners?
Yeah I was wondering about lower level listening, think there's some diffrent settings on the back like apartment, corner placed etc.
It's the opposite, the lower the volume the higher the extension, that's also what the kc62 does! DSP magic
@@MT-eb2dx interesting. Might have to see if I can demo one.
@@MT-eb2dx the beauty of dynamic EQ.
It has outstanding low volume performance just like it's little brother kc62. The extension is available and powerful even at low volume.
Hi Nemo, love your reviews. Question how would you characterize the sound of the sub, meaning JL Audio subs, bw, and rel ht series are dry and Rel TX is warmer or wet. Where does this fall? Hope question makes sense
I don't use those descriptors but I understand what you mean, KF92 is gonna be on the wet side for sure.
Its amazing how they defy physics time and again 😅
I bought the SVS SB3000 for mainly small size/weight. I play 70% music/30% movies. Would this be a step up or down? Price is not a consideration.
hey Weiss, so it's gonna play cleaner and lower for sure but personal taste may play a factor here. SVS gives you that bass that's on the dominant side (spl style) where KEF is more in the middle of SPL & SQ style subs so the KEF is cleaner with it's presentation and certainly does extend lower. I consider it an upgrade for those with compact spaces. The cool thing is KEF is fairly popular so you should be able to demo one in most major cities.
@@NemoPropaganda Thanks for your response. Have you ever heard a Swarm application? Four 8-10" subwoofers one in each corner. I'm thinking of the 10s for $400 hooked up with their wireless transmitters. $1,600 for four might sound incredible? I have never heard it.
@@WWeiss-nv5vz I have heard of it but I take the "less is more" approach to audio.
@@NemoPropaganda True, two subs is plenty!
For $2k I would have hoped they offered it in white, to match other models of their speakers...not.
ah yes indeed, that was perhaps a bit of a missed opportunity.
Great review as always Nemo! Any idea when you are going to get the G22's in (as mentioned in a previous Rythmik video)? I want to pull the trigger on a sub but I feel like I need your input on that one first.
I have the G22 already, if you're in the discord (which is free) I usually post early impressions there, you can also ask there for early impressions on anything that has not been covered yet and I will share them if I have them.
Great review. I’ve always really been interested in this sub and the Balanced force 210 from Martin Logan.
I almost got my hands on one but it sold right as I emailed the seller :(
@@NemoPropaganda damn, maybe one day. The built in room correction seems like an excellent feature
What sub would you prefer for bass in movies? 2x Kef KF92 or 2x Rel HT1205 mk2 ? Already got 2x Rel S/510 for music by high level but looking for pure LFE use.
you want more watery rumble ultra low frequency go for the KF92, it's an absolute monster in terms of extension. If you want more tactile, precise bass go for the 1205v2, it doesn't get as low but still has great extension and you'd save a ton of money. Either options is fantastic in my book!
Hey Nemo, thanks for all your reviews! The listening area is 20x13 all though it extends being an open concept living room to about 20x25. Will this KF92 be sufficient for movies 70% Music 30%
I'd say start with one, if you need a second one that could be a goal for next year maybe. How much bass is "enough" is a tough question to answer, listening habits and personal taste vary greatly and open room concepts can be challenging. A few guys in my free discord own the KF92 so maybe hop in and ask their opinion.
Regarding 100% music system. Irrelevant of room size. When it comes to speed articulation detail etc would you say the KF92 is REALLY the equal of KC62 ? If you give KC62 say 95/100 in those areas what would you give KF92 ?
The video covers all my thoughts regarding the two compared to each other. I don't have anything further to expand on.
Nice review, I think for me 2xKC62 will be more than enough
Should be more than enough for most unless the room is really large or you like it really loud.
Great review!
Thank you bro!
I wonder what’s a small or big room. For example how much m2 for the kc62 or go for kc92.
When referring to room size I am referring to audioholics room size standard: small room is under 1500sqft, medium is 1500sqft to 3000sqft.
@@NemoPropaganda 1500sqft for medium? Wow that’s very large here in Europe 🙈 it’s 139m2..
@@Natan9000 sorry brother, I meant to say cubic feet, bass fills the volume of the room. You can google audioholics room size rating and you'll find their article.
Would you say this is comparable to the SVS sb3000? I know the 3000 is larger, but with the little bit extra power of the kef thought they may be somewhat similar 🤷🏼♂️
Funny you should ask because 2 9" drivers like the ones found on the KF92 does equal a single 13" driver so the comparison is fair with respect to cone surface area and they have similar power at 1000w and 800w respectively and both are compact. Unfortunately I couldn't really say which one could play louder as I don't test max SPL. The double the price KF92 does take an easy win for low end extension and overall sound however.
Nemo, question on placement and if getting 2 of them... With their drivers on the left and right instead of facing into the room as is with traditional subs my concern is I have a console that houses my equipment so these would have one woofer hitting the side room walls and the other into the console 3 feet away on either side. If I turn them facing into the room then one sub is facing the back wall. Can you elaborate on what your experience with placement was compared to "regular" front firing subs in your room? Thx ✊🏽
Hey ben, I tested that a lot with both KF92 and KC62 and I didn't find anything conclusive. They seemed to sound great regardless of how I had them faced in my room. There was slight phase shifts as I rotated them of course but that is to be expected and every room will react differently to that.
@@NemoPropaganda oh okay cool. thx for the feed back ! 👍🏽
I don't have one yet but the manual lists the recommend minimum distance from a wall at 3".
@@michaelbriggs1477 thx 👍🏽
I know this is an old reply but when I had the KF92 I tried it with the drivers facing the sides and with them front to back and I much preferred the way KEF designed it with the drivers on the left and right.
The b&w db d series subs is as small and can go as low in Hz as the kef 62 and 92 then.
But so expensive! $3500 for the cheapest DB3D and $4500 for DB2D 😳😳😳
Love the depth of the review! I have a 18' x 14' x 8' ceilings. Thinking about getting two of these. Would that be enough for low extension? Thanks broski!
oh yeah! one will extend like crazy too, it's just about how loud do you want it, if you really are considering this sub I suggest you hop in my free discord as there are a few users who already own them so you can get some real world feedback from owners. Link is in the description.
@@NemoPropaganda Thank you so much for responding, MUCH APPRECIATED
Price aside what is your opinion between this sub and a Rythmik 15 or 18 inch
My opinion is pretty simple, the E15 is the more capable, if you can fit it, go for it! With the KF92 a good chunk of your money & value is going towards that smaller form factor. If you don't need or care for that small form factor the E15 is an easy choice. I have only heard F18 in a theater setting so cannot really comment too much on its musical prowess but I'm sure it's class leading for a woofer it's size.
These are discontinued and on sale in Canada around $2000. My room is large 13x40 8' ceiling. Primary use is 2.1 for music. The listening area is about halfwayI currently have def tech sc4000. Ilistened to a REL t9x and loved it at low - med volume good recordings. But when listening to metal from the 80s and 90s I couldn't get enough output from of it. A rhythmik f12se delivered to the border is about $1800 Canadian. My speakers are kef r3. How would you compare the 3 for music? For waf less than 16" cubed and looks are factors
I truly appreciate your reviews and perspective.
if you liked the T9X and need more output I'd suggest a single F12SE, a single REL S510, or a pair of T9X. The KF92 is an outstanding subwoofer but its main strength is its ability to deliver strong low end reinforcement in an extremely compact form factor. The KF92 is more at home in a small to medium theater where extremely deep extension from a small subwoofer is needed.
@NemoPropaganda thank you. Very fast reply. Yes for the WAF I think it needs to be a single sub, so probably the f12se based on mostly your info and specs. Ps. I just subscribed. My first ever
@@chadridsdale9970 welcome to the show.
Hope you're still checking these comments. Got a question. I'm considering this sub for my home theatre setup. It's a medium-small room (it doubles as my bedroom lol). I saw people saying to buy two even with that room size...but I sit very close to my TV and speakers (5-7 feet). Will 1 of these subs be enough to enjoy that below 20hz subbass? I do 50% movie and 50% music.
When people say below 20hz usualy they mean below 30hz. Below 20hz is infrasonic and if you want to notice infrasonics at substantial output you generally need something like a pair of 18" drivers. That being said the KF92 is the lowest extending sub I know of given its phsycial size. I don't think you can do better. If you don't listen too loud you might be better off with a pair of KC62 but either option gives crazy low extension for how small they are.
@@NemoPropaganda Thanks for the info! I'll try with just one and pray that it will be fine because it will be placed so close to my listening position. If I feel like I need two, I'll get a 2nd one on the used market. If I get lucky on the used price, i'll end up spending about the same as two new kc62s ;) But yeah, my listening levels aren't that loud because I sit so close to my speakers and TV.
@@CSXLoser 1 is pretty capable my bro. I use a single KC62 in my living room which is considerably larger.

I would for sure take the KF92 for its much stronger extension.
Thanks@@NemoPropaganda! One more question - If you were give the choice between 1 KF92 or 2 KC62s, which would you pick? Assuming room coverage was not an issue.
@@mikesalz dual KC62 would be the easy choice for me.

@@samsneediii1793 yeah for sure bro, you have a tower of power, you should be good for the next decade :)
Hi Nemo, how would you compare the KF92 and the Rythmik F12SE if one or the other was to be used in a music only system? Thanks for your help and all the great reviews! J
F12SE will play louder, better note to note distinction, and better midbass. F12SE is the more articulate subwoofer, the KEF is smaller by a good amount yet extends like crazy, it’s SQ doesn’t match Rythmik but its still very good. Just to be clear F12 also extends very low.
@@NemoPropaganda Thank you for that! Would you say the KC62 has better articulation and note to note distinction? I'm mainly concerned about high quality music reproduction. I don't listen to a lot of electronic music. My (large) monitors taper off below 65, even though they are like -13 dB at 38 Hz. Thanks!
@@WookieeBlaylock KC62 is the best tiny subwoofer in the world and I absolutely love it but the full size F12 is better in every way.
Thanks for the great vids. I have a Naim Uniti Atom and a pair of Tekton Lore Reference speakers. I currently have a Klipsch Cinema 600 sound bar which comes with a 10 inch sub, I think rated to 28hz. Do you think adding the KF92 to the Tektons would be good? Room isn't huge.
Speakers go to 37hz
the KF92 is an extension monster! If you're looking to take that 37hz down into the teens the KF92 will do it. If this is for theater you'll love it. Now if its a music only system and you don't listen too loud you might be able to get away with the smaller KC62 but everyone I know who owns the KF92 absolutely loves it.
@@NemoPropaganda with the Uniti Atom, I'm limited to preamp out connection. For that I'd use RCA cables?
@@jjnewbold correct!
@@NemoPropaganda pretty close to pulling the trigger on this. I'm mostly looking to get more detail from movies than I've been hearing from my sound bar system. Extension and clarity/definition over volume/pressurization. Anything from Rhythmik you'd recommend over this for the price? They seem to have high bang for buck. Thanks!
If I have kef speakers is it easier to pair them with lets say kc62 or kf92 cause they are the same company or is rythmik f12se also very easy to pair with kef speakers? I know that rythmik is better sub generaly but seamlesly pairing is what I want to know which would be better choice? Cheers
I do not believe speakers must be matched with the same brand sub.
Great then i'm more into rhytmik:) in other video I asked you about subs maybe you didn't see it. The sub that you reviewed Rel s510 is it comparable to Rhytmik F12 SE or if its better how much is it better what are the differences. I didn't hear non of those two so if you could describe it to make a better picture of the differences between those two. I'm a music producer so I need a sub for music..
Great review as usual. Tnx for that, but now you have made my task even more difficult. I have all system from kef. Kef r700 fronts, kef surrounds, atmos etc.. So I decide go for KF92, but now came out new rel ht/1510 predator.. Same price range, same rms + - . just the size difference
I have fairly large open plan living room ( +/-50 m2 ). I'm listening more house music and movies so it would be good if he went down to 20 hz and less
What would be your recommendation between these two?

Great review , would like if you could review KEF KUBE 12B, thx
I will look into it :)
Thanks for your reviews. Any thoughts on KF92 vs Rythmik L12 (or pair of L12's), for mix of HT and Music? For a 200-ish sq ft room, size and aesthetic are factors.
before I advise may I ask, if you have KF92 money and aesthetics are a factor why is the L12 part of the discussion? It's fairly simple/ugly compared to the KF92 and Rythmiks F12SE is far more beautiful so shall we discuss KF92 vs F12SE instead? Or is there some reason the F12SE is not an option for you? lmk!
Part ignorance (so appreciate your reviews). But the F12 is an option, budget wise.
Part was shying away from large size and weight, aesthetically and after lugging a 70 lb sub around a number of moves over the years, and likely more moves to come, And class D with dual voltage also good to have if move abroad. But it is an option, if sound-wise materialy better
Also wasn't sure if two subs or a dual fired sub would be better for sound through the room, as not a dedicated theater room and doors often open into other rooms.
From your answer, you like the F12 for that budget, it sounds like?
@@pushkin168 okay, back to L12 vs KF92 then, both are fantastic but the L12 isn't winning any awards in the looks department, it's a very utilitarian look with a vinyl finished cabinet. It will have much better midbass than the KF92 and more consistent low frequency extension. The KF92 is of course much more beautiful, can extend much lower but there is a caveat here, the KF92 uses an active DSP, as you demand more volume from it the bass extension will be reduced and at say 100dB it will not have the extension that the L12 can produce. With that said if you're looking for the smallest sub with the deepest frequency extension and you will not push the sub too loud then the KF92 is without equal but if you're hunting for 100+dB output and low frequency extension at the same time the L12 may be preferred. TLDR the KF92 is an excellent LFE sub for those with smaller to medium spaces who want to recreate a movie theater environment albeit at much lower volumes.
@@NemoPropaganda Thanks again. Saw your video on the REL HT/1003 MKii could be an option as well. Appreciate your reviews. Happy Holidays.
@@pushkin168 that's a great option too, possibly the smallest of the bunch, if that is what's most important it's an excellent sub.
Nice review and onto an entirely different topic. I'm curious about that crazy cool looking sofa setup in the "soundbar living room". Do you happen to recall the manufacturer and make ? Love the design aesthetic and it looks incredibly comfy for modern styled furniture.
Hey brother thank you so much, I just bought it a few months ago and absolutely love it!!! It's the Diego Sectional available through Scandinavian Designs. Price is a bit high but it's made in Italy and the fabric is high quality and easy to spot clean when needed. It replaced a Lumin I had (from CB2) which didn't live up to expectations and was really hard on my back. The Diego certainly is very comfortable and very supportive. I still use a pillow for my lower back but I have an extreme arch and always need extra support.
Comparing to a Rel T7x isn't a fair fight. Price and sizewise, comparison would be more relevant against REL T9x. I'd love to see a review of the Dynaudio 18S / Sub6 against this too.
T9X would have the same outcome. Dynaudio subs…. Meh… i had a pair of the sub6 but they had some issues and could not be reviewed. I lost interest after that.
@@NemoPropaganda I've been looking at the Dyn subs but there aren't any good reviews!
@@MRPC5 I tried bro, I bought a pair of Sub6 on the used market for review, both of them didn't work. It was very odd. The seller was very adamant that they worked prior to the sale.
How does this compare to the Arendal 1961 1S? Great review.
Both are very good subwoofers. If you're more concerned with max output go for the 1961, if you are more concerned with maximum extension the KF92 is impossible to beat for its size but it is more that double the price. If you can afford the KF92 but want to play louder then go for the 1723 1S. It will extend lower than the 1961 and sound much cleaner all while having serious output potential.
Thanks for reply. I am more concerned with texture and cleanness than output.
@@CsRajkai You are describing 1723 1S. I think that is what you will be most happy with. KF92 is really great but the biggest benifit is crazy strong extension in a small package, especially at lower volumes. 1961 is great all around sub but 1723 is more what you are describing.
How does it compare with your Rythmik E15HP2? I'm torn between the two. Will be running a pair with my KEF R series system. Thanks!
The KF92 is always going to come down to this: if it's output is sufficient for the room it's hard to find a better theater sub regardless of the size. If the output is not sufficient then generally speaking nearly anything larger will be preferable. The E15hp2 is substantially larger and will have considerably more headroom at all frequencies as well as a larger sense of scale. As far as musical performance I like the KC62 better than the KF92 but the E15hp2 is better than both. Very few brands have the fidelity of Rythmik.
@Nemo Propaganda Thanks for the reply. I currently have the Klipsch RP-280FAs and 2 R-115SWs in the front, and it's pretty tight sandwiched between the front walls. I have a little bit of room to toe in the fronts, but not enough to get them perfectly toed into the center. The KEF R7's bases are 2" wider than the RP-280FAs, so if I used equally wide subs, the problem would only be worse. The E15 is 2.5" more narrow than the R-115SW, so that will be about equal out to my current setup, but the extra room provided by the smaller KF92 would be nice. And the aesthetics would match a bit better with the R speakers. I can get the E15HP2 in gloss black for $1789 shipped and found some open box deals on the KF92 for a little bit less than that, so the price is irrelevant. I'm also in a condo with a sensitive neighbor, so total output isn't a big factor either. Pretty torn, because I know the E15 is the better sub, but it's a lot bigger and heavier, which might not be worth it. Oh, also, I live on the third floor with stairs, so that sounds like a pain.
@@Dasbeerboots based on everything you've said I think you are a perfect KF92 customer. What you're trying to accomplish is exactly what its designed for.
@@NemoPropaganda Thanks for the help. I'll go demo the KF92. Might walk away with a couple of them.
@@Dasbeerboots it's pretty amazing bro, everyone in my discord that owns them absolutely loves them!
Speaking of high level outputs, I have a 1200W Definitive SuperCube II. It is connected to an AudioLab DAC as a preamp outputting via low level to the sub, and balanced output to Adam active speakers. Do you think it would be a good idea to take a digital output from the DAC to an integrated amp so that I can get high level output to the sub.
I have a Sonos gen 3 wireless sub that has 2 opposing woofers like the KEF. It is the only silent woofer I have ever owned. I am guessing the KEFs have a similar property.
Generally speaking there is no inherent benefit to using highlevel unless your suboutput is crappy then highlevel will be a cleaner output signal. Only way to know is to try.
great insight
as a kef dealer i really wish they were able to communicate this with the frequency response figures as they’re identical to the kc62
Ah yes indeed, the two subwoofers on paper will seem very similar to the average consumer. The difference should be easy enough to resolve with a demo though :)
@@NemoPropaganda What if you cannot get a demo? Would you base your recommendation between the KC62 and KF92 on room size, content or what you are pairing them with?
@@andrewdorolek5948 KC62 is an easy choice for stereo or small room lower volume theater while KF92 is better for larger room or louder outputs both are extremely good and sound very similar, easy way to look at it is the larger KF92 has more output.
In the past I would have laughed at someone for having a Heavy thing problem but once you have to carry those things up a tight curved stairs by yourself or even with two people you will want to throw that sh** away hahaha.
45 minutes of struggle, smashing your finger, getting bruised, almost having it slip on your toe or on your whole body will make you never want to have anything heavier than you are capable carrying alone
Sounds like a great Sub. To bad that it's out of my price range but I'll keep it noted for the future.
yeah, I'm not 21 anymore lol
Thanks for the great review. How is it compared to the Arendal 1961 which costs less than half and is narrower?
Hey what's up dude! The 1961 1s is narrower for sure but I think it's overall size is similar if not maybe a little bit bigger so I would expect it to be able to play a bit louder at the limit and it can still extend plenty low but not as low as the KF92. Both are really good subwoofers, the KEF is all about as much extension out of a tiny box where the Arendal is more so just a great subwoofer overall and it's major feature is the narrow design. If you don't need a small subwoofer like the KF92 for sure you will have tons more performance from something larger like the 1723 1S and you can of course buy 2 1961 1s for the price of 1 KF92 so a lot of the money you're spending on the KF92 is to have maximum extension while taking up very little space. For some people who have limited space it's an easy decision but if you have lots of space the big value of the KF92 may be less important to you. Hope that helps put things in perspective.
@@NemoPropaganda Thanks,actually I have a place limition the only problem that I have with the kf92 is that it is "firing" for both sides and the spot that I have for it is blocked on the left side, only 5-15 centimeters.
On the other hand the Rendal output is from rhe right side.

Kef kf92 vs jl audio e110? And will u ever review the jtr rs1 subwoofer?.
I covered that in the E110 video: ua-cam.com/video/MRQ26TB_c94/v-deo.html I don't think I will review JTR as they are very large.
Hi, I have a HT room that's 20ft x 14ft x 7ft
After seeing this review, I am looking into one of these subs - either 1 KEF KF92 OR dual Rythmik FVX12s (basically around the same cost).
My main speakers go pretty low - they have a FR from 20 hz (the speakers have a built-in powered sub), but probably start rolling off around 40 hz, so I would need a sub that does well from 40-45hz down and is solely for HT.
Any thoughts on this?
Dual FVX12 would have A LOT more in them overall vs a single KF92. The pair of FVX12 would extend almost as low and play much much louder and with outstanding SQ. If you want a single the E15HP2 will extend just as low as the KF92 but play much louder but of course both these options are much larger and the whole point of the KF92 is extension of a huge sub in a small package. If you don't need the small package the larger Rythmiks will offer up a ton more return for your dollar.
@@NemoPropaganda awesome, thanks for the reply!
Is the KF92 one of the premiere options for a 50% Movies 50% Music setup? The only issue I have is that I have a very large space (open floor plan great room) even if the audio setup is isolated to about 1/3rd of it. The sub needs to be relatively compact for WAF reasons, so no bigger than 12" I think in terms of footprint. Dual subs should be possible down the line. For reference, the living room area is about 15'x19' with 10' ceilings and the left side opens up to the dining room and kitchen and extends another 30' or so.
Hi Reinku, KF92 remains one of my higest recommendations for mixed systems where compact enclosures are required, of course I understand the concern for output also. It's hard to say if it will be enough bass or not because everyone has different taste for how much bass they want. Sometimes we just have to try it, if it doesn't work out you can always add a second one or return it for a larger option. Conversly the JL E110 should offer up more output in a similar sized enclosure and is also an excellent choice but a little more expensive.
@@NemoPropaganda Thank you for the quick response! I'll take a look at the JL E110. The subs I've been considering are the SB-3000, Rythmik F12SE, and KF92 so far. It's been very difficult trying to figure out which one I'd like to give my first shot to. I was pretty ready to go for the F12SE but your review gave me pause since I felt it might be slightly lacking for the HT side of things.
@@reiniku5830 F12SE is a lot bigger than KF92 but if you can fit F12SE that would get my vote easily. The real value of the KF92 is for those that really need a compact yet powerful solution for aesthetics or physical limitation.
@@NemoPropaganda I think I can just barely fit it. How do you think it'll perform for HT? I think I'm ready to audition it and see if it will work for both my music and HT needs.
@@reiniku5830 The F12SE? Extremely well!! It's a very capable 12" for music and movies. Easily one of the best, I still own mine and love it. If you lived close I'd say come listen.
Hi so a REL T7X is better for pure 2 channel music than this KEF?
very different subwoofers, t7x is all about fidelity, KF92 is all about extension from a small package.
I am about to buy keg towers speakers would like to know if it can be matched perfectly with the q series speakers for 50/50 use
I'm not sure, I have not heard the KEF towers and the only Q speaker I've heard is the Q150.
Hey i asked about REL HT/1205 MKII in one of your videos and i told you that i sold SB 1000 pro, i wonder maybe i should get KEF 62? remember my room is 4.3m lenght 2.6m wide and 2.55m high. Mostly i listen music but i am basshead kinda. I would never guess that sub of that size i mean KEF can go so low and have 1000w power DAMN !! i wonder how it would play in my room. Main speakers are KEF q100. (a little bass they have and dont go audibly below 55hz ?)
The KC62 is a badass sub for sure but if you don't need the small size I'd still go for the 1205 MK2.
my sold sb 1000 pro was under desk on my left (when i listed i take chair back, desk is open), if u put here 1205 mk II well it could be tight xd i wonder how the sound diffrience is for room of that size KEF is 1,480 dollars here, mk ii is 1177,99 dolars@@NemoPropaganda
@@ultrasone8450 oh alright, yeah go for the KC62 then, it's awesome!
KEF would be noticeable "weaker" than rel? sb 1000 pro 70% max power was more than enought for this room :D u know i am bass head but not psycho as u said in rel vid i dont need 2x 15" subs xD but i like the authority, slam etc@@NemoPropaganda
How would you compare this to the JL E112 regardless of price for 50/50 music movies to pair with ls50 meta speakers.
those are 2 really different subs my bro, the JL E112 is a good bit more expensive and possibly the loudest sub you can buy in that small a cabinet. JL is all about extreme output out of a compact enclosure while the KF92 is all about extreme extension out of a compact enclosure. The value of the KF92 is having as much extension as possible out of an incredibly small cabinet for those who don't need too much output. Both subs can play loud and get low but the JL gets way louder and KF92 gets a lot lower (albeit at lower volumes). At louder volumes the JL E112 can do everything the KF92 can do and more. As far as sound quality goes, the JL takes the edge also, it's a serious beast of a subwoofer and worth every penny more it costs. For the record a more fair comparison would be the E110 but the result would be similar.
great review! I wish you'll review the Rel S510 😍 (or even dual S510)
I too hope to check it out some day :)
Yes love to see a real battle head to head with 510 & 92 seperated review in music and movies. Real killer will be a review first singels then duel fight 🥰🥁🥁✅💥
@@feggelindh7584 the 1510 & KF92 have been compared via txt in the free discord, feel free to join.
Seems to tick all the boxes for me, but for mostly music, is one of these enough in an 18’ x 23’ room? (Approx 3,330ft3). Until I could add a second one at least…
that's a tough question to answer my friend, how much bass is enough is like asking how much salt on french fries is enough, everyone has different taste. I would consider your room to be sized Large and I think 2 would be ideal. Most people should be happy with 1 but some people have very extreme taste for bass.
@@NemoPropaganda thanks, I don’t need to shake the room at 90dB+. I plan on having dual subs, but if they’re higher end ones like this I’ll have to live with one for some time before adding a second one, unless one is satisfying.
@@gustoaudio8711 one could be satisfying, one was more than I'd ever need in my room but I have a smaller room. I think you gotta just try it and have the experience.
@@NemoPropaganda I have a hunch 2x Rel T/9x is what would suit me most for the easiest system and room integration with enough quality and power, but then the price casts serious doubts when you look around. I’m not sure one would cut it and I’d have to live with one for some significant time at that price. For a few hundred more than a single T/9x I could get dual SVS SV2000 Pro’s or dual 3000 Micros. And for the price of dual T/9x’s I could have an SB16 Ultra with change to spare, or a Rel S812 for only €10 more… not to mention dual SB3000 for over €500 less. So it becomes one of the most difficult decisions I’ve come across in hifi, but maybe I’m overthinking it - physical size is a major factor in the decision though which is why I’m so interested in the Kef.
Regards the KF92, it’s only about €150 less than an SB4000 which no doubt would do the job on its own, I’m not quite sure how a single KF92 would compete in this size room.
@@gustoaudio8711 Hey Gusto, you are cross shopping brands that should not be cross shopped as they are totallly opposite sounds of bass, I made this short video to help explain the difference: ua-cam.com/video/rEz03XkcslI/v-deo.htmlsi=AKPphGTJUvV9motY
For home theater application: 2 subs? For home hifi: 1 sub or 2?
Duals will usually sound better than singles.
@@NemoPropaganda Are duals especially good for surround video sources? I don’t have that experience.
@@gbass7328 in generaly if you can get them setup right dual subs are almost always going to sound better than 1 regardless of your choice in content.
@@NemoPropaganda 👍🏻
Between this and the REL T9x or S/510 for music only which one would you get? thing is I'm getting a deal on the S510 and this KF92 but can't decide. a demo is not possible either. I do have personal experience with the T7x though as I own that one but want to upgrade. thank you.
I listen to all genres but mostly rock, trance, symphony, acoustic, pop.
I have not heard the s510. The real strength of the KF92 is in mixed systems where this tiny sub can belt out crazy low end extension for a real theater experience yet is also great with music but if you're only going to be listening to music then a lot of the value of the KF92 isn't going to be used so it's better to get the T9X. Think of it like this, the strength of the T9X is in that 30hz and up region where music is, the strength of the KF92 is 30hz and below where most low freq effects are so music only, go for T9X, more theater focused, go for KF92.
@@NemoPropaganda thank you! It is 100% music focused. I use different subs in the theater. The Martin Logan Depth i x2

How about some of the higher end BW subs. They should be comparable to the kefs
I find them to be extremely expensive, $4500 for the dual opposed 10"!! You can get a pair of KF92 instead and still save $500.
I'm very curious how this compares to the B&W DB3D and DB2D.
I wonder too but I don't have any way to get a review sample from B&W so all I know is the DB range is very expensive :)
@@NemoPropaganda expensive and beautiful 😏
Hi!! KEF KF92 small box like Svs 3000 micro !!! Is Kef much better? can you make it more percussive and higher sound pressure? Thank you!!
the KEF is extremely better, its not even close.
@@NemoPropaganda Thank you!! Unfortunately, my problem is that I can't listen to it and I have nothing to compare it to because it's quite expensive .. but I was afraid it was like the svs.. Small volume and can't give sound pressure... I thought maybe Rel t7 or t9 or ht 1205 and now I found this Kef 92...Music and movies about 50-50%
@@tibitibi1407 the KF92 can play rather loud but if you want louder the 1205 MK2 might play a little louder.
@@NemoPropaganda Thank you very much!!! I was just afraid if the Kef 92 can also create a small air pressure, but then surely the Kef is much better than the svs? and would the Svs sb 4000 be another alternative!?
@@tibitibi1407 If you really want to make sure you get the right sub for your room hop in the free discord bro, plenty of guys with tons of subwoofer experience that can help you.
In terms of bass speed, which one is faster, or are the the same?
KC62 has more definition in the leading edges which will make it sound like its faster.
Because the low frequency response of KC62 and KF92 is the same ( 11hz), do you think we can still hear some difference, more extension or more rattling if the room size is the same? What I mean is, because one is using 6.5" drivers and other one is using 9" drivers, can we feel any difference if we play them in the same small room and on the same volume level just because of the driver size? I already own a KC62 and planning to buy KF92 for the living room but it is not so big so I might still get away with KC62 but if driver size creates any difference, I would go for KF92 even though claim low frequency is the same for both. Thank you.
Their specs are misleading as that 11hz is only at low volume. As the volume rises so does that extension figure for the kc62. I imagine at volume the differences between the 2 subs will be readily apparent.
the difference between the two is more apparent at louder volumes as Neil C pointed out. Since you already have the 62 try it in your living room first perhaps? But yes the 92 will play it's lowest frequencies at higher volumes than it's little brother.
correct!
How does this compare to the Arendal 1723 1S?
oh bro, 1723 1s is much larger, digs down into the teens, and plays those lower frequencies with substantially more output than the much smaller KF92. Always remember for smaller subs like the SVS Micro, KEF KF92 or KC62, etc... A lot of the money you are spending is going towards the size so if the size is not a big deal for you then for sure get something bigger like the 1723 1S.
@@NemoPropaganda Very helpful, thanks man. I'm about to do a new living room setup. Looking for a matching front stage with bookshelves and a single sub. Seems like the best options I can come up with are either a KEF setup with R3's, R2c, and a KF92 or Arendal with the 1723S bookshelves, 1723S center, and a 1723 1S. Would you recommend one of these setups over the other or something else altogether?
@@BClear91 I couldn't say as I havn't heard either of those sets of speakers. If you're in the free discord I'd ask there, maybe some of the users in there have that experience.
KEF really needs to send you a cube 10 or 12 demo unit so you can give us your honest thoughts on them. If you go by user reviews they are fantastic but you never see or hear about them.
I'm sure they'd send me one if I asked :) I've just been busy.
Hey Bruh…are you going to review the LS60s wireless
hey what's up bro, probably not. It looks amazing though!!

hey thank you Seoul!
Thoughts on replacing a SVS PB-1000 with this ?
I have not heard the PB-1000 but if you’re referring to the old 10” (non-pro) this should be a serious upgrade.
curious if you have reviewed golden ear subs...seem to have missed if you did...
I have not. Their design is very old, neglected, and lacks any phase or polarity control. I think there are many better options for the money.
@@NemoPropaganda Thanks! I'm starting to look for a sub to go with raidho xt-1's - very fast...audio only system - roll off at 50-60hz. Any thoughts on that coherence/blending would be #1 priority, aesthetics #2 (although I may get overruled on that)
@@bferguson001 ooo that's a big money speaker :). Okay this is actually a great question. The kings of speed are Rythmik, REL, and shockingly enough JL Audio. JL Audio's E110 being more SPL focused does it with force, it's tone is heavy (review coming soon), and aggressive. If you like heavier bass go for the JL. Rythmik's F12SE is the total opposite, it handles delicate passages better, has a better midbass region, and of course amazing transient response and bass fidelity with bass that more comes from an ink black background. If you want Audiophile bass this is the one. Lastly (and certainly not least) the REL T9X, the most beautiful of the bunch is going to be very similar to the Rythmik but with a warmer tone, less extension but slightly more bass detail. If you have not already seen this please watch ua-cam.com/video/rEz03XkcslI/v-deo.html. It will help you decide if you're more REL & Rythmik customer vs JL Audio. If you decide you are more on the REL & Rythmik side then they have totally different looks so it should be easy to choose.
@@NemoPropaganda Thanks for the thoughtful reply! The used market for the Raidho's is where to find them...really appreciate your thoughts
@@bferguson001 I'm always happy to help :)
Did you ever run into problem of it not turning on at low volumes? If so how did you address it?
I did not, my preamp RCA output is a bit on the high side though.
Excellent review!! I am debating between KC62 and this. My room is about 25sq meters, and I listen to music around your volumes: 75-80dB, and very rare 85-90db. I don’t need window shaking bass, but I do want to hear those low notes when listening to music or movies at those volume levels. Would a KC62 be enough or should I go for the KF92? I would go for the 92, but I start to believe it’s overkill for my current room and listening levels..
try kc62 first then, if it's not enough you can return it for KF92 :)
Would love to see you do a review o the Perlisten speaker and sub range
maybe one day, their smallest sub is still 100 lbs which is a little too heavy for me to review and it comes on a pallet.
Apartment or condo? KC62
House? KF92
Easy Peasy :)
ahahaha, it's simple logic but that certainly is an easy way to decide. Though the KC62 could still disturb neighbors :D
@@NemoPropaganda In an apartment or condo building, ANY sub could disturb neighbors. Trust me, I'm on a condo board. :D
@@ayokay123 bro! I'm on the board of my condo also, I hate it so much but nobody else will do it :(. I feel like a hall monitor, everyone is so stupid. I was patrolling the neighborhood one day, a guy asked what I was doing, I explained I was on the board and just making sure nobody left their trash bins out and he responded "damn they just pay you to drive around in this cool car all day?" to which I replied, NO! I don't get paid for this, and kept the "you idiot" part to myself.
@@NemoPropaganda Precisely. My building has over 300 units and it's near. impossible to get anybody to run for the board because it's such a miserable, thankless job. And yes, we also have a few idiot owners who either think we're getting paid or receiving kickbacks from vendors. Such ungrateful wretches. You bust your butt to protect the value of their hard earned asset and a simple thank-you is too much to ask for. Fortunately, we hire a management company for the day-to-day stuff. We only get two or three owners attending the monthly zoom meetings, so I guess we're doing something right. Owners only care if they think there's a possibility of a special assessment. You know all this.
Hoo-boy...got me torn between this KF92 and the Rhythmik G22 to replace an older Outlaw LFM-1 Compact 10" ported, downfiring sub. I use my system roughly 60/40 leaned towards film, and the G22 miiiight be overkill in my space, but having such "precise" capability and lower extension, even at a reduced volume (and for less $$$) seems like fun and makes it something that could be with me for the long haul, as I don't tend to collect or swap often, if I like something.
both are seriously good options but there is a substantial size difference between the two. A big chunk of what you're paying for in the KF92 is the compact form factor, if you don't value that the G22 would be the logical choice as you'd save some money while gaining more output and precision. But if you don't need the output and instead value the small size, KF92 starts to make a lot of sense. You just need to decide what you value more.
@@NemoPropaganda Thanks, that's pretty much what I'd been thinking, and I've been doing my pros/cons lists, for sure. I also came across the Goldenear SuperSub X, which seems to live in a similar space as these other two. Really makes me wish there were more places to go get some hands (and ears) on these things before purchasing!
@@31emxof golden ear is not on the same level bro, take that shit off your list.
@@NemoPropaganda Appreciate the candor!
Great job bro!
Love that sub but not for me! 😎👍
I am always wondering how to differentiate between bass output vs bass depth?
output is how loud it can play. Bass depth can mean 1 of 2 things. Either it is referring to the low frequency extension or it is referring to a sound characteristic where the bass sounds deep when it hits, like there is good weight & decay.
This or the SVS Micro Sub for music only system?
SVS Micro is more comparable to the KC62 and this is a situation where the more expensive unit (KC62) is the better one. If you have the budget for it the KC62 is incredible.
@@NemoPropaganda I currently own an SVS SB-3000 mainly for music, would you consider the KF92 a large upgrade over my current sub for music?
(I've actually had the chance to try a friend's kc62 and while the bass quality was great, the output was lackluster for my room)
@@RealDiGiPHiX KF92 is an upgrade in some ways like extension and how clean it plays but the SB3000 has a stronger attack to its bass and can play louder so it just depends what you value.
How does two kc62's compared to one kf92 ?
their sound is very similar being made by the same brand. Dual KC62 sound awesome though I'm not sure which setup would play louder.
I pretty much understand all descriptions of subs sound quality, all that words like texture, extension, tone character and etc. But can someone describe what is authority, I'm struggling to understand what that means 🤔
mmm, it's hard to describe sound because we can't see it or touch it so maybe this sounds kind of wonky but to me authority is a combination of a big sense of scale and effortlessness at the same time almost like the subwoofer is happy and not strained at all. Kind of like accellerating in a car with a large engine, even though your foot is not all the way down you can feel the power, you know theres more of it, you're accellerating fast, and you can tell its easy for the car.
@@NemoPropagandaThanks, I understand perfectly what you mean, effortless sound really makes a huge difference and allows you to enjoy it much more.
Lol'd @ "soundbar living room" 🤣 Your living room looks to be about the same size as mine, or maybe even slightly bigger. But, I've got Arendal 1723 Monitor's in mine and have had pretty large towers the likes of Revel F208's crammed in there! I was never any good at physics so I just pretend it doesn't exist 😭
You have the same kicked in area where the TV is? That's what makes it so hard to place a sub but I remember someone in the discord had dual Emotiva RS11 in a similar kick out.
I think I would take a T9x over this for music and movies.
But if I didn't have neighbours that I like, I would get this.
both are great subs, fairly different though.
They just released the new version, KC92. Curious what you think 🤓😁
yessir! Still a few weeks away from review samples being available but I will review it at some point for sure!

How does this compare to a rel 1510?
from the FAQ section of my free discord: The KF92 is always going to come down to this: if it's output is sufficient for the room it's hard to find a better theater sub regardless of the size. If the output is not sufficient then generally speaking nearly anything larger will be preferable. The 1510 is substantially larger and should have considerably more headroom at all frequencies as well as a larger sense of scale. As far as musical performance I'm actually going to give a slight edge to the REL 1510 as it's leading edges are a little more well defined while the KF92 has more of a softness to its leading edges. Lastly the 1510 has a bit of a heavier tone to it while the KF92 has a slightly lighter tone by direct comparison. If KF92 is between SPL & SQ the 1510 is just a hair over towards the SPL side only due to it's heavier presentation. All other aspects of the 1510 are very SQ. Worth considering is the KF92 employs active DSP meaning as output increases frequency roll off becomes more aggressive while the REL 1510 will be more consistent at higher volumes. Both subs perform well at lower volumes so you certainly can shove a 1510 in a smaller room or a larger room where as KF92 is really for lower volumes or smaller rooms. Hope this helps.
