Wow, this was the best explanation of this concept I've ever heard! I've called Denon, Polk and SVS. None of them were able to come close to this. In fact, I was more confused after I called. SVS suggested setting it to LFE while Denon suggested LFE+Main, but I didn't know WHY. I didn't know that setting it to LFE+Main negates the Small/Large and Crossover settings. Thank you!
Thanks for explaining it so clearly man! I've looked at multiple videos trying to figure out what the LFE connection on my subwoofer was for and I finally figured it out after watching your video.

Good video and you're doing a great job of demystifying home theatre. I have Tannoy Revolution DC6T's for fronts and for ages was never very happy with them. They weren't producing much sound and seemed insipid and struggled to cope. I have a budget Denon AVR and thought I needed an upgrade. Recently I changed my speaker setting from Small to Large, going against what most 'experts' recommend. Holy smoke: this changed everything! I'm getting much better imaging and sound stage and starting to enjoy movies all over again! I am using LFE+Main, but my advice to anyone is - experiment. Sound is a personal thing and it depends on the room and the equipment. So don't take anyone's word for it, pick a dynamic scene you're familiar with and watch it over again at different settings (Large vs small speaker and LFE + Main vs LFE).
Great video. You answered many of the questions I had. Explanations were clear. I was better informed and knowledgeable after your video that I was before it... and that's the goal. 🔥👍🏾👏🏾
Thanks K., Yamaha receiver set to LFE...Front (main) speakers set to small. Crossover set at 60hz. Polk Speaker set (7) + 1 sub = 7.1 setup. I then ran the Ypao to calibrate and balance the speakers placement. OMG - this changed the ratio of bass and highs because the center channel is standing out like I wanted. The surround backs are playing louder for more of the effect in certain settings. Even listening to the radio sounds totally different (better). Excellent tutorial, you helped change my listening experience. I had my system set too loud for the space. Most appreciated - I now have better control over the bass output because of the sub volume...🤔😊
i have klipsch r-620f and my subwoofer is klipsch allso i have the subwoofer at LFE SETUP WITH THE CORSSOVER AT 60 HZ ALL BY THE WAY ALL MY SPEAKERS ARE KLIPSCH AND THE SOUND IS GREAT IT SOUND BETER AT 60HZ THAN 80 HZ
Kpaceguy let me start by saying how much I've learned about home theater setups since I stumbled upon your videos! Thanx so much. You are extremely knowledgeable and you do a great job of helping me understand this complex process of home theater procedures. You've been my go to guy for some time now. Great video here.. Just picked up a new onkyo TX-RZ1100 and trying to get all phases working properly. Front mains are Jamo D590 which deliver great bass. Best performance is full band with just LFE and seems to sound the best. Looking forward to watching more of your videos thanks again.
@@Kpaceguy Question. What is your personal preference for Speakers/2 channel playback set at? And why? Large or Small Subwoofer yes or no Subwoofer mode? With or without LFE or LFE + Mains Crossover settings Thanks in advance!
@007g35 large. Therefore all those settings you asked about are off. Only because my speakers are very capable of playing large. Main reason I choose large is because they bass stays in my room. Doesn't disturb anyone around me and is easy to manage yet is still very present
@@Kpaceguy Got it! I appreciate the rapid response! It’s good to know I had the same settings as you suggested. I was curious if should use the same settings for movies. Always tweaking my HT set-up…I appreciate it! Bro, if I could subscribe multiple times I would! Thanks again!
Once again you bring clarity to what others believe to think everyone understands. Most companies support tell you just use LFE not explaining the difference in LFE and LFE + Main. Thanks for getting right to the point.
Excellent video, so much depends on your speakers as well as your processor/receiver. The type of dac in your processor /receiver, will play a part in the type of sound your speakers give off. . Also if you use room correction it may also influence what lfe setting you use. My current setup I run Lfe + Mains.
Awesome Video. Tried LFE+ main with my JBL 580’s and SVS PC-4000. It did not sound that great at first but set the sub crossover to 50hz w/24 db rolloff in extended mode. Me likely! Thank you for this, you earned a sub…scription
Applause to you , I’ve watched many videos on bass management, technical terms are used and I come out more confused to the point where I have to watch same video over and over again . I watched your video and completely understood it the first time watching it
Sub mode Is set to LFE only, All speakers set to small with a crossover at 80hz and the subwoofer LFE at 120hz. Front speakers is Wharfedale 11series floorspeaker and subwoofer is the SVS SB-2000 Pro.

Thank you you taught an old dog tonight AWESOME!!!
I am currently running my speakers on LFE + MAIN and I never thought about why you said my subs will be playing what my speakers are bumping. I also got all my speakers at 80hz and my subs at 120hz.
I have a Denon AVR x4500h Set at LFE+MAINS front towers Infinity Beta 50 @60 hz and large, and both my KLIPSCH SPL-120 12” subs set at 120hz, Infinity Beta™ C360 CC set at 60hz and small, rears at 90hz small. It sounds AWSOME!
I've been using LFE+Main with my mains at 150hz crossover to help combat some 80-150hz room modes I couldn't get rid of from my mains. Moving the subs around to boost those frequencies then calibrating them together is good result
Both Large Center & Front floor standing speakers at 40 hz , …rest all Small on 80 hz & select only LFF 120 hz instead of LFE + Main.. gives. crisp & balance sound all together. This setting for JBL studio series speakers & Three JBL subwoofers with Marantz SR 8012
Good explanation, but to be clear, when I set my receiver to "subwoofer+" it does NOT send the same signal to the subwoofers as it does to the mains. It actually sends the LFE signal and the LOW frequencies of the left and right channels below whatever I set the low pass filter to regardless of whether I set the mains to large or small.
+1 for the clarification @Kpaceguy: confusion is you didn't specify *which* crossover - speaker or sub LP filter. (irrespective, a great explanation. thanks!)
So even if I've set my speakers to (large) and go back in to set the crossovers respectively..... is it still considered full range even if it's set to large but a little tweak in crossovers?
I just recently set my receiver to LFE only as my front speakers are large floor standing, Energy RC-70s and go down to 31hz. I believe that this is the best settings for my configuration. Sub is Energy 10"
You should always set your LCR to small no matter how low you think your mains go down to ,remember setting your speakers to small will ensure all low frequencies are sent to your subwoofer(s) what there design for.
Thanks for the. It is really good. I have denon x1700h and taha harmony 606 v3 two floor standing with bi wiring center and suround with 6 ohm could you please suggest frequency, db and db setting.
I keep playing with both settings. I have Front Towers that go down to 30hz, hence at times I set them to LARGE with LFE + MAIN. at times I set them to SMALL and crossover at 60hz. Not sure which sounds better. 🤔
The AVR info is quite clear. What is still a little confusing is which input of the sub to use, the LFE or the “Sub” input. Most higher end subs give you the option,but the suggestions are not always clear, and sometimes contradictory between brands. For example I have both old and current RELS and it is suggested that both the low level and the LFE can be used at the same time. This always seems weird and seems to add gain. Suggestions to this detail of the chain? BTW also using Denon on one of the systems.
@@Kpaceguy True. But since soundtracks contain music and Sfax, dis etc, that contain low end above the 80 hz cutoff of LFE, it seems you would need the low pass if your mains are “Small” and you need the sub to play up into say 100?
yhi senn lots of clips to DAY , BUT THIS HELP ME TO UNDERSTAND IT NOW AND I ITS BETTER ALL. BUT MY KLIPS SPEKERS HAVE AMPLEFIER IN THEM BY POWER AND NOT SAYS AUTOMATIK ENABLE DISEBLE AND A TURN BUTTON TO GIVE MORE POWER IN THE BASS IN THIS FRONT STANDING SPEEKERS AN LHE STANS LIKE AUDIO RED WITW BUT STANDS OUT IN??
I have it in LFE + main , I change it to LFE to tested because I dont like how the bass sound in the towers in front so after see your argument about LFE and LFE + main ,I change it to LFE
I recently got a Klipsch 400W subwoofer for my birthday and tried setting it up with my Denon AVR1612 receiver, and couldn't figure out why no bass was coming out of the subwoofer but now understand the system automatically set the two tower speakers to large. They are B&W 684's I believe (1 tweeter and 2 woofers). I am not sure what settings to try, so am curious what you would recommend. I am leaning towards setting the towers to small, then leaving the subwoofer on LFE only, but what should the crossover be? Thank you!
Great explanation as always......please make video on Speaker RMS and recommend amplifier watt support like my polk es60 support 20 to 300 watt but what is RMS of speakers
That was a good explanation. I have Martin Logan 60XTi and my speakers set to small with crossover frequency of 80hz. My bass setting set to LFE+Main. They are powerful speakers and can play frequencies between 40 to 25000 hz. Do I need that settings for my setup ?
Well, I really didn't have that take on LFE +main. I currently have my RF7s set to large with Crossover at 60 Hz, and lfe+main. It never seems boomy to me, but my gain isn't cranked all the way up on my subwoofer, klipsch 12 inch. Receiver denon x6500h, 2*RF7s, rc7, 2*rs35s, 2*rb35s, 2*rp500sa, and 2*rp140sa.
Gene delasallo from audioholics has said in many of his videos that the L.F.E. + Mains only works when speakers are set to large therefor eliminating any type of bass management . Only speakers set to small are able to be bass managed . But every youtube expert has different opinions . it is all somewhat confusing to me.
I’ve got Klipsch rp280f towers, 504c center, the bigger surrounds which model exactly escapes me right now, some heights on the front wall and an SVS PB1000 sub. After watching this I’m thinking I need to set everything to small, choose “LFE” and set my crossover to 60Hz for the fronts and 80hz for everything else?
Hey Kyle. I’m setting up my ht and have a question? Can I have my rear towers set about four feet from the back wall and not have any diminishing of sound?
There can be a problem when your receiver has lfe only output connector and your sub has line in only, there can be no info in manual that you have to set crossover to max(150-200) and set speakers to little or you will be in lfe+main mode and sub does not work properly(only lfe sounds come through).
Bro what my subwoofer hz should be? I mean i'm using my bookshelves and center at 80hz, including towers. So my subwoofer hz should be same with them or higher or lower?
I've got a question. I also have tower speakers that can play down to 40Hz or lower. I have a Marantz AVP. If I were to set my speakers to Large but still set a crossover, say at 80Hz, and then set the subs to LFE only.... would that mean that my towers play full range while the subs play LFE and only the mains' frequencies below 80Hz? (I hope that was clear.) Or would the subs only play LFE no matter what crossovers I set for the Large mains?
If you set your speakers to large and do lfe + main your sub essentially plays everything your mains play until you reach the upper limit of your sub. Usually 200hz. And will still play it's dedicated LFE
@@Kpaceguy In that case, I don't understand why Marantz still lets me set a crossover if I set my mains to Large and engage LFE+Main. Would you consider that an error on Marantz' end?
The Bass Management of the AVR only kicks in when u set it to SMALL, hence it needs the crossovers to manage. In LARGE, the speakers play full band, hence the crossover does not have any relevance. That's how I understand it. Would that be correct?
If your subs have a physical crossover adjustment, couldn't you still run LFE+Main without over bloating a particular range as long as it's correctly set?
Hello Kev, I know this tutorial is over a year old but I’m just now seeing it and I wanted to let you know what I’m running. I have Bowers and Wilkins CM-10 S2, And a 12 inch power sub by JL audio. I’m running my tower speakers as (small) and my crossover is at 80Hz. I also have my settings set at (LFE) and not LFE +Maine. What do you think? Thanks, Fred.
Marantz SR8012 Cerwin Vega XLS215 fronts Cerwin Vega XLS-15S 15" Front Firing Powered Subwoofer ×2 All other surrounds big Cerwin Vegas LFE + Mains all day You can never have enough bass... NEVER!!!!
Great Video. ! Thanks. I have big front speakers (Focal 926) and a sub. the focal spec: 38Hz - 23kHz , The sub : 35-160Hz . Don't know if I need to set the Focal to large or small. If large why not enjoy full frequencies ? Why to set small with crossover ? And do I need LFE+Main Also , If LFE is Movie only , Do I need to set on Stereo - 2 Channels ? Thanks
Just because it reaches that low doesn't mean it does it well. You'd have to turn it quite loud to hear those lower notes and that causes distortion. You also need a new sub. Lol
@@mrronenza I'd set the speakers to small and find a crossover that blends best with the sub but I would highly consider getting a lower digging sub. You're missing SO MUCH bass
I have mine set to LFE+Main and have very muddy bass. My front mains are Speakerlabs S30s that can go very low and do no need help from subs. So, should I go LFE with small? Or If it is possible LFE with large front mains. I am confused.
Need help with minidsp setup..when running audussey after I install the mini, do I tell sys I have no sub and allow mini dsp to control them or tell it I have one sub, run audussey then go back and cancel Crossover set by sys
LFE + Mains that feature isnt in my yamaha receiver settings . I just set all my speakers to small and the crossover to 90hz and have the LFE connection from my subs to my receiver and Hunky Dory.
Is it ok if I have my fronts & center set to 80hz (the range starts at 60hrz) on the back sticker, the surrounds I set to 90hz (the range starts at 70hz) on the back sticker? Set them all to small & I set the LFE + Mains to on & crossover at 120hz to my Klipsch 12? Denon avr 2600H AVR. Thanks 😎
@@Kpaceguy Respect 👊 for the video explanation & for the reply, I keep watching this vid from time to time just so I know I have understood it correctly & by you replying confirms that so a huge thanks & big up 🙏 Also just subscribed so will check the rest of your content.
But if the speaker is small bookshelf and put it on large with life+main that speaker is planning full range, isent that bad because a small bookshelf can't handle the low very well..
What do you suggest for Bose acoustimass 6 series iii? Lfe or lfe+main. Also do u have any idea about lfe knob on bose am6 sub and at what position should i set
It's a bit confusing when you say that with the LFE+Main setting, the subwoofer will play all the frequencies that the main speakers are playing. That makes it sound as if the subs will play up to 20,000Hz or whatever. Surely you mean that the subs will play the main sound, but only whatever falls below the crossover, with some overlap of course?
Well the sub itself has its own frequency cut off built in to the amp. That's the only thing stopping it from playing very high. So the sub will play as high as it's capable of which typically is 200-250hz with overlap every single frequency in lfe+main regardless the crossover. The crossover only works on the speakers themselves in lfe + main
Dear Sir, My question is my front left and right speaker are floor standing speaker and center and surround are bookself type speaker, I am using Denon AVR X550BT, I don't want to set my front speaker small becuae i think if i set small, then all sound quality will be loss to play in front L & R. My front speaker frequency range from 38Hz to 22KHz, kindly suggest what will be my speaker setting, and also suggest what is the difference between floor standing with book self spkeaer.
@@Kpaceguy Sir, AVR is 5.2 channel, I am using Polk Audio T50, 30, 15 spkeaer set, what will be crossover frequency of all speaker can u please explain ?
I use a denon avr2807, b&w dm602 s3 and a ASW600 sub. If i set it to lfe only the sub is never working. If i use lfe+main it is to much base. I dont know what to do. 😂
Hey man, great vid! Refresing to hear someone say that setting it to LFE + Main can be the way to go. Most sound people always say to just put it on LFE, 120hz and that's it. I would love to know what's your opinion on setting the LPF for LFE at 80hz instead of 120hz. Many sound experts say to put it on 120hz, but I once saw this vid on Audioholics and they had Anthony Grimani as a guest and he said (and I saw that more other experts said it as well) that they didn't agree with that and that they always set the setting to 80 or 90hz. Because it's not a hard cut-off and setting it too high can introduce problems in your bass. And also he said that LFE rarely goes over 80hz anyway. Personalty, I'm split. Sometimes 120hz sounds better, but 80 also sounds great a lot of times and fixes a lot of issues. The vid he said it in was called: ''Get the Best Bass for Your Home Theater'' (I can't remember what part it was).
@@Kpaceguy I see, I don't have that option. But have you ever tried to put it at something like 80 or have you ever heard about the theory. In some cases here and there, it did achieve cleaner bass, but mostly it's best at 120.
james here, i have JBL studio 530 bookshelf speakers 40-45000 -6b and SVS dual SB2000 subs in a 20-25ft room. could you suggest the crossover setting for the sub. this is a 2ch setup. thanks
@@Kpaceguy i have been going back and forth between 60, 80, 90, 100, and even 150. seems like i cant dial in what sounds best to my ears! what would you do?
1:45 Wait, so if I crossover all 5 main speakers at 80hz and set Bass Management to only LFE then where all the missing content from 80hz and below go?
@@Kpaceguy So the 80hz and below contents will still be reproduced by the subwoofer inconjuction with the dedicated LFE when Bass Mangement is set to LFE only and Speaker Size is Small, correct? Seems like the LFE + Mains only benefitial to those who has towers and set their speakers to Large.
Underststanding you have, possibly your sub have a built in crossover, most have. But think the receiver must have an upper range limit and not sending the full signal to the subwoofer.
@@velocci6666 No it also affects the main speakers, its also sending the sub to the main speakers. I recommend using LFE only and set speakers to small and set the desired crossover. (80hz)
@@andreaschristiansen8572 yes that's the way I have it to. So in other words, it makes the mains and the subs the same, except the sub can't play anything higher than 120hz or so anyways.
@@velocci6666 It's personal preference but to me it doesn't make sense to cut good tower speakers off at 80hz if they can play down to 40 hz. You don't need to set 80hz crossover with good speakers that's an old way of thinking. It's more immersive when you let those towers go down to what they are capable of. Also if you don't have really good subs setting it this way helps them out.
LFE + Main with a 60hz crossover. Not cutting my towers off at 80hz when they can go all the way down to 40hz. That's an old way of thinking in my opinion. More immersive when you use towers to their potential otherwise it becomes a waste of money buying good speakers.
you are wrong at the aend - if you have small satellites you want #lfe only so you domn t get distorsiom 0 if you have huge speaker satelites you have both options available fdepending how you like you basse - also every speaker has a resonace frecvency tranfered to the room so no speaker sounds the same in every room hence you can select wahat sounds nicer to you - if it s a big room i m thinking less bass more mid and tweet so you don t get reverb and go more power in sattelites so lft only etc,,,, it s more complex that you explained here
LFE + Main is really only great for Pure Direct music, because pure direct disables bass management and there's no way to get bass out of the subs in stereo music. LFE + Main allows this to happen in direct and pure direct, but it will not be accurate. After fully calibrating my system, LFE + Main actually loses bass, it cancels certain frequencies out, I've found, even after time alignment. I use a crossover of 60hz, all speakers small, and that's the smoothest bass response I have gotten. 80hz was not as good. TLDR: LFE is best, the crossover is based on your speakers and room, LFE + Main is only good for pure direct IMO.
Love your videos, and I'm a faithful subscriber but your understanding of this topic is a bit off. For most users, especially those with smaller speakers, LFE with small speaker settings will be the optimal setting with a 80-100hz crossover. Below is a detailed explanation given by Ed Mullen of SVS. “Here is the best way to understand Small/Large , LFE/LFE+Main and the LPF for LFE. Small applies a 12 dB/octave high pass to the speaker at the selected crossover frequency. Small sends a duplicate signal to the subwoofer and applies a 24 dB/octave low pass to the subwoofer at the selected crossover frequency. LFE means the subwoofer gets the LFE channel and redirected bass from any channels set to Small. Large sends that channel a full-range signal. This is also known as ‘Full Band’. LFE+Main sends a duplicate signal to the subwoofer for any channel set to Large and applies a 24 dB/octave low pass to the subwoofer at the selected ‘crossover’ frequency1. When set to LFE+Main, the subwoofer still gets the LFE channel and redirected bass from any other channels still set to Small. 1 Note if the mains are set to Large and the subwoofer mode is set to LFE, there is no crossover selection available for the mains. If the mains are set to Large and LFE+Main is selected, then the ‘crossover’ selection becomes available for the mains. This really isn’t a true ‘crossover’ at all, because the mains are still being sent a full-range signal. What the ‘crossover’ becomes when LFE+Main is selected is the low pass filter setting for the duplicate signal being sent to the subwoofer. In this sense, the user can select the amount of ‘overlap’ between the mains and the subwoofer. This distinction is not well understood by most enthusiasts, nor is it well communicated by the AVR GUI menu. It suggests or implies a crossover is still being applied to the mains when they are set to Large, when in reality that is not the case. The LPF for LFE is the low pass filter setting for the LFE channel. Normally this is set to 120 Hz, since that is typically the upper limit used by DVD mixing engineers.”
So no one talks about what the Sub crossover should be set at? so if you have your setup set to small speakers and crossovers set to 80hz everything below 80hz goto the sub but wouldnt your sub need its crossover set to 80hz to receive the higher hz base freq. Most subs inc mine is set to like 45hz wouldnt 80hz make the sub muffled??
I have tons of videos about crossover. Yes you still need your sub crossover to at least match the speakers otherwise that information gets sent, but not reproduced
Wow, this was the best explanation of this concept I've ever heard! I've called Denon, Polk and SVS. None of them were able to come close to this. In fact, I was more confused after I called. SVS suggested setting it to LFE while Denon suggested LFE+Main, but I didn't know WHY. I didn't know that setting it to LFE+Main negates the Small/Large and Crossover settings. Thank you!
I've called 2 different companies for advice. Emotiva was excellent and Klipsch was terrible.
You are right SVS does just say just use LFE.
SVS was right. For 99% of users LFE with small speakers selected and a crossover on each channel is the ideal setting.
This video is much NEEDED. Thanks for the continuing edification on home theater.

I have a Denon AVR x4500h
Set at LFE+MAINS front towers Infinity Beta 50 @60 hz and large, and both my KLIPSCH SPL-120 12” subs set at 120hz, Infinity Beta™ C360 CC set at 60hz and small, rears at 90hz small. It sounds AWSOME!
I've been using LFE+Main with my mains at 150hz crossover to help combat some 80-150hz room modes I couldn't get rid of from my mains. Moving the subs around to boost those frequencies then calibrating them together is good result
Both Large Center & Front floor standing speakers at 40 hz , …rest all Small on 80 hz & select only LFF 120 hz instead of LFE + Main.. gives. crisp & balance sound all together. This setting for JBL studio series speakers & Three JBL subwoofers with Marantz SR 8012
Good explanation, but to be clear, when I set my receiver to "subwoofer+" it does NOT send the same signal to the subwoofers as it does to the mains. It actually sends the LFE signal and the LOW frequencies of the left and right channels below whatever I set the low pass filter to regardless of whether I set the mains to large or small.
Yes that is called a crossover
Mark, you are correct and Kpaceguy has his explanation totally wrong.
+1 for the clarification
@Kpaceguy: confusion is you didn't specify *which* crossover - speaker or sub LP filter. (irrespective, a great explanation. thanks!)
@@petpeevepaul those are in my crossover videos
So even if I've set my speakers to (large) and go back in to set the crossovers respectively..... is it still considered full range even if it's set to large but a little tweak in crossovers?
I just recently set my receiver to LFE only as my front speakers are large floor standing, Energy RC-70s and go down to 31hz. I believe that this is the best settings for my configuration. Sub is Energy 10"
You should always set your LCR to small no matter how low you think your mains go down to ,remember setting your speakers to small will ensure all low frequencies are sent to your subwoofer(s) what there design for.
Thanks for the. It is really good. I have denon x1700h and taha harmony 606 v3 two floor standing with bi wiring center and suround with 6 ohm could you please suggest frequency, db and db setting.
I keep playing with both settings. I have Front Towers that go down to 30hz, hence at times I set them to LARGE with LFE + MAIN. at times I set them to SMALL and crossover at 60hz. Not sure which sounds better. 🤔
The AVR info is quite clear. What is still a little confusing is which input of the sub to use, the LFE or the “Sub” input. Most higher end subs give you the option,but the suggestions are not always clear, and sometimes contradictory between brands. For example I have both old and current RELS and it is suggested that both the low level and the LFE can be used at the same time. This always seems weird and seems to add gain. Suggestions to this detail of the chain? BTW also using Denon on one of the systems.
You can do both on REL subs but typically LFE is the best option with home theater
@@Kpaceguy True. But since soundtracks contain music and Sfax, dis etc, that contain low end above the 80 hz cutoff of LFE, it seems you would need the low pass if your mains are “Small” and you need the sub to play up into say 100?
yhi senn lots of clips to DAY , BUT THIS HELP ME TO UNDERSTAND IT NOW AND I ITS BETTER ALL. BUT MY KLIPS SPEKERS HAVE AMPLEFIER IN THEM BY POWER AND NOT SAYS AUTOMATIK ENABLE DISEBLE AND A TURN BUTTON TO GIVE MORE POWER IN THE BASS IN THIS FRONT STANDING SPEEKERS AN LHE STANS LIKE AUDIO RED WITW BUT STANDS OUT IN??
I have it in LFE + main , I change it to LFE to tested because I dont like how the bass sound in the towers in front so after see your argument about LFE and LFE + main ,I change it to LFE
I recently got a Klipsch 400W subwoofer for my birthday and tried setting it up with my Denon AVR1612 receiver, and couldn't figure out why no bass was coming out of the subwoofer but now understand the system automatically set the two tower speakers to large. They are B&W 684's I believe (1 tweeter and 2 woofers). I am not sure what settings to try, so am curious what you would recommend. I am leaning towards setting the towers to small, then leaving the subwoofer on LFE only, but what should the crossover be? Thank you!
Exactly what you should do
Great explanation as always......please make video on Speaker RMS and recommend amplifier watt support like my polk es60 support 20 to 300 watt but what is RMS of speakers
I got you!
@@Kpaceguy thanks
That was a good explanation. I have Martin Logan 60XTi and my speakers set to small with crossover frequency of 80hz. My bass setting set to LFE+Main. They are powerful speakers and can play frequencies between 40 to 25000 hz. Do I need that settings for my setup ?
Nope
Well, I really didn't have that take on LFE +main. I currently have my RF7s set to large with Crossover at 60 Hz, and lfe+main. It never seems boomy to me, but my gain isn't cranked all the way up on my subwoofer, klipsch 12 inch. Receiver denon x6500h, 2*RF7s, rc7, 2*rs35s, 2*rb35s, 2*rp500sa, and 2*rp140sa.
Gene delasallo from audioholics has said in many of his videos that the L.F.E. + Mains only works when speakers are set to large therefor eliminating any type of bass management . Only speakers set to small are able to be bass managed . But every youtube expert has different opinions . it is all somewhat confusing to me.
@@herbtarlick12that is true. But once you set it to LFE+MAINS u can then go back and re-adjust the crossover point for bass management
I’ve got Klipsch rp280f towers, 504c center, the bigger surrounds which model exactly escapes me right now, some heights on the front wall and an SVS PB1000 sub. After watching this I’m thinking I need to set everything to small, choose “LFE” and set my crossover to 60Hz for the fronts and 80hz for everything else?
Good starting point. Just trust your ears
Hey Kyle. I’m setting up my ht and have a question? Can I have my rear towers set about four feet from the back wall and not have any diminishing of sound?
It's preferred
There can be a problem when your receiver has lfe only output connector and your sub has line in only, there can be no info in manual that you have to set crossover to max(150-200) and set speakers to little or you will be in lfe+main mode and sub does not work properly(only lfe sounds come through).
Bro what my subwoofer hz should be? I mean i'm using my bookshelves and center at 80hz, including towers. So my subwoofer hz should be same with them or higher or lower?
Same
@@Kpaceguy thank you 🙏🏻
So... Which configuration do I need to hear my subwoofer like a freakin 90s disco with all the "boom boom"??
LFE + Main
I've got a question. I also have tower speakers that can play down to 40Hz or lower. I have a Marantz AVP. If I were to set my speakers to Large but still set a crossover, say at 80Hz, and then set the subs to LFE only.... would that mean that my towers play full range while the subs play LFE and only the mains' frequencies below 80Hz? (I hope that was clear.) Or would the subs only play LFE no matter what crossovers I set for the Large mains?
If you set your speakers to large and do lfe + main your sub essentially plays everything your mains play until you reach the upper limit of your sub. Usually 200hz. And will still play it's dedicated LFE
@@Kpaceguy In that case, I don't understand why Marantz still lets me set a crossover if I set my mains to Large and engage LFE+Main. Would you consider that an error on Marantz' end?
It probably lets you set it but it's only engaged in "small"
The Bass Management of the AVR only kicks in when u set it to SMALL, hence it needs the crossovers to manage. In LARGE, the speakers play full band, hence the crossover does not have any relevance. That's how I understand it. Would that be correct?
If your subs have a physical crossover adjustment, couldn't you still run LFE+Main without over bloating a particular range as long as it's correctly set?
Yes
Hello Kev, I know this tutorial is over a year old but I’m just now seeing it and I wanted to let you know what I’m running. I have Bowers and Wilkins CM-10 S2, And a 12 inch power sub by JL audio. I’m running my tower speakers as (small) and my crossover is at 80Hz. I also have my settings set at (LFE) and not LFE +Maine.
What do you think?
Thanks, Fred.
That's the correct setting

Great Video. ! Thanks. I have big front speakers (Focal 926) and a sub. the focal spec: 38Hz - 23kHz , The sub : 35-160Hz . Don't know if I need to set the Focal to large or small. If large why not enjoy full frequencies ? Why to set small with crossover ? And do I need LFE+Main Also , If LFE is Movie only , Do I need to set on Stereo - 2 Channels ? Thanks
Just because it reaches that low doesn't mean it does it well. You'd have to turn it quite loud to hear those lower notes and that causes distortion. You also need a new sub. Lol
@@Kpaceguy Thank you. So what are you recommend setting up figures ?
@@mrronenza I'd set the speakers to small and find a crossover that blends best with the sub but I would highly consider getting a lower digging sub. You're missing SO MUCH bass
@@Kpaceguy Thank you !
I have mine set to LFE+Main and have very muddy bass. My front mains are Speakerlabs S30s that can go very low and do no need help from subs. So, should I go LFE with small? Or If it is possible LFE with large front mains. I am confused.
Go lfe and set crossover to small and crossover the mains as low as you you want

What do you suggest for Bose acoustimass 6 series iii? Lfe or lfe+main.
Also do u have any idea about lfe knob on bose am6 sub and at what position should i set
Lfe + main
What about lfe knob setting on sub
Can u help me with crossovers for speakers and sub for bose am6
@@tarunsri6023 don't set a crossover. The bose speakers have it built in. Set your speakers to large
So speakers to large. Sub lfe+main at 80hz. Is tht ok?
It's a bit confusing when you say that with the LFE+Main setting, the subwoofer will play all the frequencies that the main speakers are playing. That makes it sound as if the subs will play up to 20,000Hz or whatever. Surely you mean that the subs will play the main sound, but only whatever falls below the crossover, with some overlap of course?
Well the sub itself has its own frequency cut off built in to the amp. That's the only thing stopping it from playing very high. So the sub will play as high as it's capable of which typically is 200-250hz with overlap every single frequency in lfe+main regardless the crossover. The crossover only works on the speakers themselves in lfe + main
@@Kpaceguy Doesn't the receiver's LPF setting cut it off at 120Hz or whatever is is set to?
Dear Sir,
My question is my front left and right speaker are floor standing speaker and center and surround are bookself type speaker, I am using Denon AVR X550BT, I don't want to set my front speaker small becuae i think if i set small, then all sound quality will be loss to play in front L & R.

Small. Crossover at 40. That's their full range

Use what you like the most
Hey man, great vid! Refresing to hear someone say that setting it to LFE + Main can be the way to go. Most sound people always say to just put it on LFE, 120hz and that's it.
I would love to know what's your opinion on setting the LPF for LFE at 80hz instead of 120hz. Many sound experts say to put it on 120hz, but I once saw this vid on Audioholics and they had Anthony Grimani as a guest and he said (and I saw that more other experts said it as well) that they didn't agree with that and that they always set the setting to 80 or 90hz. Because it's not a hard cut-off and setting it too high can introduce problems in your bass. And also he said that LFE rarely goes over 80hz anyway. Personalty, I'm split. Sometimes 120hz sounds better, but 80 also sounds great a lot of times and fixes a lot of issues.
The vid he said it in was called: ''Get the Best Bass for Your Home Theater'' (I can't remember what part it was).
I have mine set to 120 and have always been fine. But I have the ability to set how quickly my subwoofer cuts off everything above it
@@Kpaceguy I see, I don't have that option. But have you ever tried to put it at something like 80 or have you ever heard about the theory. In some cases here and there, it did achieve cleaner bass, but mostly it's best at 120.

1:45 Wait, so if I crossover all 5 main speakers at 80hz and set Bass Management to only LFE then where all the missing content from 80hz and below go?
Subwoofer
@@Kpaceguy So the 80hz and below contents will still be reproduced by the subwoofer inconjuction with the dedicated LFE when Bass Mangement is set to LFE only and Speaker Size is Small, correct? Seems like the LFE + Mains only benefitial to those who has towers and set their speakers to Large.
@@sonang7721 you pretty much got it
@@Kpaceguy Thanks for the reply man.👍
LFE? That's the name of the Expo I attend every yr...."Lowlifes & Freaks Expo' : )
With LFE + main, the sub plays all the frequencies 20hz to 20khz? But subs can’t play that entire range. Am I misunderstanding you?
Underststanding you have, possibly your sub have a built in crossover, most have. But think the receiver must have an upper range limit and not sending the full signal to the subwoofer.
@@andreaschristiansen8572 so that setting only affects the sub?
@@velocci6666 No it also affects the main speakers, its also sending the sub to the main speakers. I recommend using LFE only and set speakers to small and set the desired crossover. (80hz)
@@andreaschristiansen8572 yes that's the way I have it to. So in other words, it makes the mains and the subs the same, except the sub can't play anything higher than 120hz or so anyways.
@@velocci6666 It's personal preference but to me it doesn't make sense to cut good tower speakers off at 80hz if they can play down to 40 hz. You don't need to set 80hz crossover with good speakers that's an old way of thinking. It's more immersive when you let those towers go down to what they are capable of. Also if you don't have really good subs setting it this way helps them out.
Did Tristan like his closet kpace? He not bin about for a week.maybe he got arrested again.
LFE + Main with a 60hz crossover. Not cutting my towers off at 80hz when they can go all the way down to 40hz. That's an old way of thinking in my opinion. More immersive when you use towers to their potential otherwise it becomes a waste of money buying good speakers.
100% agree
you are wrong at the aend - if you have small satellites you want #lfe only so you domn t get distorsiom 0 if you have huge speaker satelites you have both options available fdepending how you like you basse - also every speaker has a resonace frecvency tranfered to the room so no speaker sounds the same in every room hence you can select wahat sounds nicer to you - if it s a big room i m thinking less bass more mid and tweet so you don t get reverb and go more power in sattelites so lft only etc,,,, it s more complex that you explained here
You said doodie
LFE + Main is really only great for Pure Direct music, because pure direct disables bass management and there's no way to get bass out of the subs in stereo music. LFE + Main allows this to happen in direct and pure direct, but it will not be accurate.
After fully calibrating my system, LFE + Main actually loses bass, it cancels certain frequencies out, I've found, even after time alignment. I use a crossover of 60hz, all speakers small, and that's the smoothest bass response I have gotten. 80hz was not as good.
TLDR: LFE is best, the crossover is based on your speakers and room, LFE + Main is only good for pure direct IMO.
Oh great, now I have to turn down the bass on Billie Eilish even more.
Love your videos, and I'm a faithful subscriber but your understanding of this topic is a bit off. For most users, especially those with smaller speakers, LFE with small speaker settings will be the optimal setting with a 80-100hz crossover. Below is a detailed explanation given by Ed Mullen of SVS.
“Here is the best way to understand Small/Large , LFE/LFE+Main and the LPF for LFE.
Small applies a 12 dB/octave high pass to the speaker at the selected crossover frequency.
Small sends a duplicate signal to the subwoofer and applies a 24 dB/octave low pass to the subwoofer at the selected crossover frequency.
LFE means the subwoofer gets the LFE channel and redirected bass from any channels set to Small.
Large sends that channel a full-range signal. This is also known as ‘Full Band’.
LFE+Main sends a duplicate signal to the subwoofer for any channel set to Large and applies a 24 dB/octave low pass to the subwoofer at the selected ‘crossover’ frequency1.
When set to LFE+Main, the subwoofer still gets the LFE channel and redirected bass from any other channels still set to Small.
1 Note if the mains are set to Large and the subwoofer mode is set to LFE, there is no crossover selection available for the mains. If the mains are set to Large and LFE+Main is selected, then the ‘crossover’ selection becomes available for the mains. This really isn’t a true ‘crossover’ at all, because the mains are still being sent a full-range signal. What the ‘crossover’ becomes when LFE+Main is selected is the low pass filter setting for the duplicate signal being sent to the subwoofer. In this sense, the user can select the amount of ‘overlap’ between the mains and the subwoofer.
This distinction is not well understood by most enthusiasts, nor is it well communicated by the AVR GUI menu. It suggests or implies a crossover is still being applied to the mains when they are set to Large, when in reality that is not the case.
The LPF for LFE is the low pass filter setting for the LFE channel. Normally this is set to 120 Hz, since that is typically the upper limit used by DVD mixing engineers.”
So no one talks about what the Sub crossover should be set at? so if you have your setup set to small speakers and crossovers set to 80hz everything below 80hz goto the sub but wouldnt your sub need its crossover set to 80hz to receive the higher hz base freq. Most subs inc mine is set to like 45hz wouldnt 80hz make the sub muffled??
I have tons of videos about crossover. Yes you still need your sub crossover to at least match the speakers otherwise that information gets sent, but not reproduced
