Thanks for this amazing review and because of this I'll be with confidence buying this subwoofer on Saturday!
QSC, making speakers 🔊 right! Glad I bought one. Great Video
Hell ya!! I just started researching hi end subs and came across the 118, you sold me!!
QSC has even made it to have upgradeable firmware. The connection is right behind the knob. You have to pop it off to see it.
You can't update the ks118s only the k.2s I believe
That is a nice sub - QSC just does it right. Thanks for the review.
I never had a high end sub the most expensive I had maybe $600 sub well all that is changing this year hopefully this month. Thanks for the reviews and most important the honesty 🙏
It's always a pleasure! Thanks for the comment and we appreciate the time you took to watch!
Great review guys. Just bought my second one last week. Definitely worth it.
Awesome!!
Thanks for the tear down video! It would be great if you guys could incorporate amplifier power testing into your videos. This is incredibly easy to do with a multimeter. I have tested a KW181 amp module and have seen roughly 70-80v running 40-60hz sine wave from a signal generator. These numbers are at the point the amp modules limiters are engaging and the clip led is coming on. You can make this test without the woofer connected. This would be very relevant info, as the claimed power output has skyrocketed from the KW181’s specs. Of course, the amp could be capable of the claimed output, but in reality limited to a number that the driver can actually handle. Point being, a 18TBX100 will never handle anywhere near 2000w RMS.
Looks better then most 18” you be shocked people when a company actually puts a better driver inside your active speaker most brands just lower budget one to suit...that looks like b&c driver...i had rcf 905as mkii didnt think much of it no way 1100watt and had same driver believe it or not as the 705 so 👎🏻! Best channel opening them up and comparing whats inside 👌🏻
Great videos guys. Would love to see a Turbosound iQ18B 3000 watts (peak) teardown and audio shootout comparison with the QSC KS118.
that is what is considered a long-throw cabinet, they will feel it to the back wall of the room! NICE.
I have 4 of the Kw181's and 2 of the KS118.....LUV EM!!!!!!!
Thanks for the review this is my next purchase to go with my RCF HDM 45A TOPS
Just got a KS118. Its not that great. I dont think its worth the price. Its really not that loud and doesnt hit the low lows too good. Might go back to guitar center and see what else they got. If i find another sub that sounds better and louder, im returning the KS118.
another great video guys. driver definitely looks like a B&C sub. would love to compare this and a yorkville at guitar center soon. really impressed with the enclosure design overall. they really should market that its a folded horn design. thats what made me get my yorkville. but the compact size of the QSC with similar power out has me considering it now.
It blew us away in every aspect!
Me interesa el yorkville ES18P en cuanto lo vendes
Probably 18tbx100
great review!!!
Awesome teardown thank guys.
One question, have you in project to teardown the QSC KS212c? I'll be awesome, regards fab.
Hi great vid!!
I think of buying the ev- etx 18sp is it better or should I go with the ks118?
Thanks
Great video! How does this compare with RCF in the same price range?
Awesome channel. Really would like to see your opinion on Proreck Pr18 18 inch subwoofer.
Please do a review of the qsc ks212c i just purchased one. Huge QSC fan have had my KW181 since 2018 now still hitting strong. Just needed more power for big gigs.
These subs worth every penny!!!!!!
good job 100 percent
Please tear down the Mackie DRM 18s. Thanks for all that you guys do!
Getting one next weeks after seeing this...thanks guy..
Updated:::i love this sub but the casters on the Back rattle like hell... to me it's too powerful for the box that its in..
thank you for letting us see the inside 👍🏻
You are quite welcome!!!
Hello, good video !! Could you one day make a demo on the TA 18 sub of thomann at 400 € with apparently a good speaker inside.
That driver is definitely really good. Wait till you see a b&c 18sw115 free air.
B&C tbx100 is the driver used by the looks of it, very good driver
Great review! Love the fact that you open the box and discuss the internals and driver. Any chance you guys are going to do a Turbosound IQ18B review some time? The Turbosound IQ's are often regarded as the cheaper alternative based on the QSC K-series.
I would love to see that iq18b review too!! My top 3 subs I'm looking at are the iq18b, srx18sb, and this ks118.
From what I've heard from others is that they don't have the low frequency response that I'm looking for like the QSC KS118, but the iq18's are loud and hit hard. I listened to 4 of them at a concert and an entire light fixture fell from the ceiling.
@@ryannrjohnson lol.. fell?? any injury? that is pretty scary
@@rsgr3963 yes, and the ceiling is about 30 feet high. Thankfully this happened after the concert while most of the people were near or already out the exit door but the music was blasting as folks were leaving, good thing it happened then because the concert was sold out and there wasn’t even much standing room so it would have hit someone because it only smashed the ground about 6 feet away from 2 people. The seating was probably the only thing that kept the splatter from hitting them. Glad you asked, cause I seen the iq18 are running around $900 dollars now, I now want a Turbosound iq18 for that price 😂
Great review brother, I really want those speakers where can I get them, any purchasing link or contact on how I can get them please?
After looking at this sub it looks like the B&C speaker series subwoofer...Makes me wanna order 4 of them from parts express website since I had 4 jbl prx718xlf powered subwoofers for an upgrade and on the plus side since that amplifier has 8 large capacitors in them no wonder that thing hits hard...I would love to hear them in person at guitar center once they bring them in soon...hell I might sell my 4 jbl prx718xlf subwoofers and buy 4 of them QSC 118 in the future....love your videos brother keep doing what you doing!!!
Thanks man, yeah this thing was absolutely insane, and I also agree that it does really look like B&C driver
I think it might be the rcf 18x401
They look like custom made by b&c, it looks like a 18rbx100 and 18tbx100 combine together... I'm sure they are made cheaper than normal OEM b&c for saving money
T-Dubbie Dubb ... And it almost looks just like the eminence definimax 4018LF as well I brought two of them not too long ago to upgrade my EV ETX Subs!
It is a b&c
Great Review bro!
Appreciate it!
I bought 4 of these and matched them with 6 QSC KLA 12's. I used an A&H SQ 6 as desk for live show. Unbelivable sound from this rig !!
Great review! Finally a English speaking review on this! No offense.
And not only is it English speaking, this is a all around great review, sound test, air free test, opinion on it, which is a great opinion, I own this beauty! But I would never take it apart due to because I want to keep my speaker in tack, don't want to mess with it at all like that.
We are glad you enjoyed! Thanks for the comment!
Thank you guys for doing this video!
How dare you suggest he speaks English! On behalf of all English speakers, I'm offended! LMAO WTF
@@kwisclubta7175 I don't understand what you're offended by snowflake.
Great video! Was wondering if you guys could tear down some more JBL stuff too, just a suggestion
Yeah we will try! Unfortunately our pockets arent bottomless and we dont have any sponsors or endorsements of any kind haha, but we will try!
Yup, the SRX818...
What is your opinion in comparison for model KW181? It looks like they are much different constructions.
Just ran across you review. I am in the market for a pair of subs. Can you review the qsc ks212c
1500 bucks!! Must be nice. It cost approx 3K in Canadian pesos. Even the K12.2 cost over 1500. Cheers great video!!! 🍻
You should tear down the EV ETX 18sp subwoofer
I think Chaz and I would be good friends. Have a car audio build that's 160+db lol.
Could you do a teardown of the JBL EON ONE compact ?
I see lots of these speakers in Taobao China ,selling around 200 USD ...they look like the same ,not sure are the same thing although .BTW ,this is a good PA subwoofer for hitting 30hz,but you need at least 20hz for bass at home
I'll take two!!
Thanks guys. I need to build a system for my band. I'd love to hear my 6 string bass through this. You think it would be a good piece for my band for playing out live. Do you think I would need 2 of these for each side of the stage or just 1 in the center? I appreciate any feedback, no pun intended. Peace, out
would love to see a free air test of the RCF 9006 / 9004
Btw, it's not a folded horn, or even a mini scoop, it's a basic bass reflex box,
The thing is that the port is flarred to prevent shuffling and port compression, that will reduce spl at high level..
Also the kw181 have the same port design as the ks118.
But hey great video !
They are very different the ks118 is angled up in a waveguide manner and even narrows near driver, creating a "loading" effect which is why I called it a horn. I will agree it's not a "folded" horn but it's definitely not the same as the kw181. Agree to disagree I suppose, thanks though we appreciate the input! Thanks for watching!
Yeah, that is some bad information with calling the box design a folded horn. Maybe take some time to research what a folded horn is as there is nothing that could remotely put that box in that category. Also, the video does not depict the port design you speak of at all. That would have been great info in the video! Sorry to sound negative, and I really do appreciate the time, effort, and enthusiasm you have put into these videos. Keep it up.
@@2DudesAudio it’s not a horn bro, the port is just tapered. Does absolutely nothing performance wise over a bass reflex
You Guys return speakers after taking them apart?
7:30 You really should get yourself a pair of JBL Selenium 18WS600, if you can get a hold of 'em. They're surely running pretty cheap right now and are very nice 18" toys.
Hi,Can I run a crossover to it even though it has one built in? If so what setting i need to put the on board crossover at? i have a dbx 234xs 2-/3-way Stereo, 4-way Mono Crossover.
Speaker is so expensive but the sound great i love it
Can your review a rcf 18” sub or fbt
How does this compare to the etx 18sp?
I would really like to see a video on the QSC E115 and E118 series.
BTW great videos on reviewing speakers!
One great fact is that there is no such speaker as good designed as these QSC speakers. Am I wrong?
We love QSC for their brains that's for sure! We also enjoy the fact that they hardly advertise, letting their speakers do all the talking, not their marketing department. It really says alot about a company.
@@2DudesAudio please I want these speakers how can I get them please, any link
Good work guys! I have the older KW118 and it pounds! I can only imagine how this would sound in my DJ setup. I would love to see you get your hands on a QSC K12.2 and take that apart!
We just might! After hearing the insanity of the ks118 we may have to venture over to their top speakers
S-1010 setup in the background?
How this thing compare to EV ETX 18inch sub?
definitly not a folder horn design, but great review of the subwoofer
Would have been nice to show more of the inside of the box
Next video should be a tear down and test of the yorkville ls801p
Would love to see you guys getting your hands on a real big sub like a dual 18 (for example a sub 8006as) or a 21 or something like that
We would love that aswell!
8006 is a 45hz box at decent volume... wich is a shame really :/
@@Cornetto1997 it was just a given example as it was the first dual 18 that came to my mind
@@laurinmasseling5836 the rcf sub 9006 goes lower. To about 30hz. The 8006 is a box catered towards live music. I would love to see them review the 9004 or 8003
How you hitting 30hz? It says in the specs 35hz at -10db is the lowest!
Also I have a idea, for you next video,
You should get a mesurement microphone, and get yourself a software like rew or even smaart V8 and start mesuring every speaker to see their frequency response.
I think it would really great to compare box and also see if manufacturers spec correspond with the reality.
We are shooting a video tomorrow of the ks118 but with a db meter just to see!
As much as I like specs and numbers, I prefer to decide on my own ears. So spending the 450$ for REW and a proper measurement microphone wont be in our future. We arent all about the numbers. More about the final product and how we hear it. Numbers will always change dependent on environment and other uncontrollable variables.
@@2DudesAudio totally agree, but when you are watching a UA-cam video is kinda hard to hear the speaker through your headphone or whatever you are listening with, so having a visual representation is really helpful to make our own judgments , and yes of course I can take your word for how good a product is,
Agree with this, the reason their channel isn’t gonna take off is because they don’t put in effort to do this. People wanna see real frequency response charts, because sometimes you can’t go test these out at stores
What do you guys think about the Ev ETX18SP perhaps you can do a review and teardown
Btw awesome video! Loved it really well explained coming from a sound engineer
2 Ks118 or 2 yorkville es18p???? 🤔🤔
I have 6 of the 181s and i have 2 of the 118s. I didnt know about the folded horn with is quite interesting. However even with that, i still love my 181a MORE than these subs.
Hi,
What's the reason, why do you prefer 181? I'd like to purchase QSC subs for live music shows. KW181 vs KS118, this is the question.
Is it better than a Mr. Microphone?
How would you rate this against a Yamaha dxs18xlf? I own one and it consistently blows me away. I've also consistently heard that it's best in class, beating subs like the JBL vrx918sp and ev etx18. Would love to see how the qsc compares with it
i wanna buy 4 subs, actually own 6 dxs18 and want to add some bass reflex to the mix, not sure if pull the trigger in those dxs18xlf or this qsc ks118 :( i cant compare them in person, so it will be a blind buy based in others experience
I'm in the market... compare it to a RCF I need something that's lighter weight..
"Your dimming lights over here!", BWAAAAAAAAH
Lmao
B&C speaker....QSC could use a néodyme transducer, they are many choice at B&C (or Beyma, RCF...etc....)
Habagat pro or storm 18 by live speaker that is good
Can you guys test / breakdown a Rockville RBG18FA 18" 3000w Active Powered Subwoofer Folded Horn.
Garbage sub
test the RCF 8004 please
You should tear down the jbl prx 812
Where did you get it for 1500 ? I only find it for 1999.00
Where is this sold for 1500?
I'd be curious to see this against the Turbosound Milan M18B. I own a pair of them and they were better than the EV ETX 18 powered subs. I sent the EVs back and got the Turbosounds. They hit incredibly well. I was pretty shocked with their performance, even outdoors. Just curious how it would stack up. I can't believe these used to sell for 500, I got them at 700 a pair, well worth the money to me. They recently went up to 800, but even at 800, I still think they will whoop anything in that price range.
I wonder about the iQ18
@@MobilediscowirralCoUk I've heard the IQ 18. They work really well too. Definitely a step up from the M18Bs. But they have a higher price as well. 1,100 currently on sweetwater.
k12.2 please 🙌🏻
Is still 1500???
It sounds pretty good but bass boss 18’s will eat that for breakfast lunch and dinner but for that price it’s not bad I went to dj expo this week and heard bassboss in person against RCF & Yorkville & they beat them both the bass is amazing and they cheapest 18’s are easily over $2000 a piece!
So overall opninion on ks118 vs KW181? Is it worth upgrading from the 181? I have two kw181s.
If you can get what you want for yours 181. I can say yes. But if you lose a lot of money my opinion is not. One sub 118 don’t going to sound more than two 181. Two vs two the 118 sounds more but not doble output. I have two kw181 and was my question until I checked.
KS118 vs RCF8004?
hi bro kindly do the patience to reply, im a home theater enthusiast. i was planning to add a pair of faital pro subwoofers to my system. Can pro subs go low to subsonic region. since home theaters need subs to play around 25 to 35 Hz region, are these 18 inch beast capable.
No, dont get faital pro or even most PA subwoofers are not intended for home theater use unless you buy just the driver and build your own enclosure tuned to a much lower frequency than what most PA subs are built to.
Hey I'm hoping you are still around and will reply as my question is would a Mackie thump 15 v4 keep up with this sub it hits 127db peak is rated 650rms and 1300w peak need to know it's also for a personal system as at first I'm getting
Yes it will sound fine. I had seismic audio 15’s before I bought my RCF tops they were 350 rms that sounded great with the KS118
It is definitely a B&C driver. Not sure which model
Do a rcf v.s. qsc
The subwoofer looks for be a B&C 18TBX100 , if that's the case impressive , better than RCF. KS118 is a winner, QSC amps are first rate and this B&C driver is also first rate. RCF's own cabinets have bad amps that fail and sometimes take out the drivers with them. They dont even sit in their own enclosure , RCF just glue everything!
Can you review the Cerwin Vega (Gibson) CVX-21 or CVXL-18?
We definitely have alot on our plate right now, we have alot of speakers we want to tear down and review but our pockets are only so deep ):
@@2DudesAudio Where are you guys located? I ended up buying a CVX-21, if you want to use it for review
@@mikelachendro488 I'm in Northern CA. Bummer.
Challenge you to test the peavey RBN215!
We definitely want to step into the dual driver market! Thanks for the suggestion!
How much RMS?
Next test the Rockville RBG18s...$339.95 for a powered 18 in. sub! See if it can bring on the bass?
Do yourself a favor buddy, stay away from anything that says rockville, specially audio equioment. They are trash
@@doctormasterdevil I concur
Do ev elx200 18sp
its $2000 now a days , would have loved to had bought this 2 yrs ago .
Hey man can you do a video on RCF sub
We are trying, money is tight especially during this quarantine
that driver looks exactly like the b &c 18tbx100
Hey do you think one of these is better than two 181s...I’ve heard rumors
That's tough to say, we do have two 181s to test against the 118 so maybe thatll be our next video!
2 Dudes Audio I would love to see that... as I’m sure others would as well...I hope the rumors not true ...I own two 181s... that would put me in a very tricky position... lol but I’m serious I would probably get one and cut my system down.... the only problem is I just bought my second one in December had no idea this was coming till after I bought it.
2 Dudes Audio and maybe you could run all three as well together and see if it gives the 4 sub effect with the 118 coupled in the middle if the 181s don’t throw off the phase if I’m using that term correctly especially if two verses 1 is close enough in power
B&C tbx100 is the driver used by the looks of it. Very good drivers!
Mine sounds like it blew and I hardly used it and never maxed it out. No visible damaged from the front but sounds like the cone is hitting something behind it. Disappointed....
I've watched so many videos on subs and I'm still waiting for someone to provide a good sound demo. If you can spend $1500 on a sub you can spend some money on a decent mic to make a decent recording. Actually don't bother. I just decided to take the niche which is wide open
Why should they spend money on a mic to please you for free?
The woofer looks suspiciously close to the B&C 18TBX100, the only difference is like the sticker on the motor
Is it relly RCF driver ?? Any idea which model ??
It's B&C TBX100
@@hardfrosmusic thanks a lot for the reply brother 😄👍
