QSC KS118 Subwoofer Bass Test / Free-air / Teardown! 

Thanks for this amazing review and because of this I'll be with confidence buying this subwoofer on Saturday!

Hell ya!! I just started researching hi end subs and came across the 118, you sold me!!

QSC, making speakers 🔊 right! Glad I bought one. Great Video

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.

That is a nice sub - QSC just does it right. Thanks for the review.

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 👌🏻

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.

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 🙏

Great review guys. Just bought my second one last week. Definitely worth it.

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

Great videos guys. Would love to see a Turbosound iQ18B 3000 watts (peak) teardown and audio shootout comparison with the QSC KS118.

thank you for letting us see the inside 👍🏻

Please tear down the Mackie DRM 18s. Thanks for all that you guys do!

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 !!

These subs worth every penny!!!!!!

B&C tbx100 is the driver used by the looks of it, very good driver

That driver is definitely really good. Wait till you see a b&c 18sw115 free air.

Getting one next weeks after seeing this...thanks guy..

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.

Awesome teardown thank guys. One question, have you in project to teardown the QSC KS212c? I'll be awesome, regards fab.

Great video! How does this compare with RCF in the same price range?

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.

Hi great vid!! I think of buying the ev- etx 18sp is it better or should I go with the ks118? Thanks

You should tear down the EV ETX 18sp subwoofer

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.

great review!!!

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

Awesome channel. Really would like to see your opinion on Proreck Pr18 18 inch subwoofer.

Great Review bro!

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.

good job 100 percent

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.

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!!!

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.

What is your opinion in comparison for model KW181? It looks like they are much different constructions.

I think Chaz and I would be good friends. Have a car audio build that's 160+db lol.

1500 bucks!! Must be nice. It cost approx 3K in Canadian pesos. Even the K12.2 cost over 1500. Cheers great video!!! 🍻

How does this compare to the etx 18sp?

You Guys return speakers after taking them apart?

Just ran across you review. I am in the market for a pair of subs. Can you review the qsc ks212c

How this thing compare to EV ETX 18inch sub?

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 !

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?

Can your review a rcf 18” sub or fbt

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

2 Ks118 or 2 yorkville es18p???? 🤔🤔

Could you do a teardown of the JBL EON ONE compact ?

Speaker is so expensive but the sound great i love it

S-1010 setup in the background?

Great video! Was wondering if you guys could tear down some more JBL stuff too, just a suggestion

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!

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.

would love to see a free air test of the RCF 9006 / 9004

I'm in the market... compare it to a RCF I need something that's lighter weight..

Next video should be a tear down and test of the yorkville ls801p

How you hitting 30hz? It says in the specs 35hz at -10db is the lowest!

Would have been nice to show more of the inside of the box

I'll take two!!

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

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.

Where did you get it for 1500 ? I only find it for 1999.00

KS118 vs RCF8004?

Why did the price increase to $2000?

Habagat pro or storm 18 by live speaker that is good

What do you guys think about the Ev ETX18SP perhaps you can do a review and teardown

B&C speaker....QSC could use a néodyme transducer, they are many choice at B&C (or Beyma, RCF...etc....)

Is it better than a Mr. Microphone?

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?

definitly not a folder horn design, but great review of the subwoofer

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 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.

"Your dimming lights over here!", BWAAAAAAAAH

Is still 1500???

test the RCF 8004 please

Where is this sold for 1500?

Can you guys test / breakdown a Rockville RBG18FA 18" 3000w Active Powered Subwoofer Folded Horn.

You should tear down the jbl prx 812

It is definitely a B&C driver. Not sure which model

So overall opninion on ks118 vs KW181? Is it worth upgrading from the 181? I have two kw181s.

How much RMS?

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.

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.

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

Do a rcf v.s. qsc

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!

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!

that driver looks exactly like the b &c 18tbx100

Challenge you to test the peavey RBN215!

Next test the Rockville RBG18s...$339.95 for a powered 18 in. sub! See if it can bring on the bass?

its $2000 now a days , would have loved to had bought this 2 yrs ago .

k12.2 please 🙌🏻

Do ev elx200 18sp

Can you review the Cerwin Vega (Gibson) CVX-21 or CVXL-18?

Hey do you think one of these is better than two 181s...I’ve heard rumors

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....

Predecessor is incorrect. Thanks.

WE ARE STILL WAITING THE REVIEW OF THE MACKIE 18S SUBWOOFER

Hey man can you do a video on RCF sub
