Building on the success of QSC's K Series, the KW181 subwoofer, like the rest of QSC's KW active loudspeakers, represents QSC's next evolutionary step in wood enclosure loudspeakers. The system engineers created the KW series to feature all the groundbreaking electronic attributes of the popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.

High Output
Like it K series predecessors, the QSC KW181 speaker features a QSC designed, 1000W (2 x 500) Class D power module. The loudspeaker is also fitted with an 18" cone transducer of the same high-quality design.

DSP
Extensive signal processing is employed throughout the QSC loudspeaker, providing levels of sonic clarity and total output that defy all expectations for a speaker in this category:
¢Intrinsic Correction: first featured in QSC's high-end line array products, it maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency, and amplitude response to a maximally flat bandpass target. The result is an active speaker that behaves equally well across the entire sound field
¢DEEP and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies
¢GuardRail protection, first introduced on QSC's GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping

Connectivity:
The QSC KW181 subwoofer speaker features dual balanced female XLR / 1/4" line level‰input, dual balanced male XLR full-range line leave out, remote gain control via a potentiometer (sold separately), and a locking IEC power connector.

Control:
The QSC KW181 speaker has an LF switch which can be set to NORM, DEEP for additional bass extension. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the QSC speaker is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation.

Premium-grade materials:
The QSC KW181 subwoofer, like all its KW Series brethren, is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, low-noise casters, and a highly protective steel grille provide for ease of transport and long-term durability. The QSC loudspeaker's integrated M10 suspension points allow for flown applications and a threaded pole receptacle provides for a positive, wobble-free connection to a threaded speaker pole (included).

Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

I did my homework. Spec'd all the major subs on the market, both single and double 18", as well as some of the other 12" ported cabs. On paper these speakers compete about evenly with the others from JBL, EV, Mackie, and others.

Then came the listening tests, and everything changed. My eternal thanks to Scott Schwarz at GC Pro Rockville Md for his assistance in letting us audition these speakers. The KW 181 simply blew me away. We do a variety of rooms, from huge ballrooms with 1000+ people to outdoor concerts to smaller nightclubs. A single pair were sufficient for one of the largest nightclubs in the area, and in the smaller clubs I had to turn them down to keep from shaking the ceiling tiles out.

After purchasing the first pair I was so sold on them I immediately went and purchased a second pair. One reason was that we wanted to get the top speakers up higher. The one drawback is that the pole isn't that long and the KW152 doesn't get up over the heads of the audience if it's set on the floor level.

Once I put the two pairs together at a large show, I was beyond blown away. The speakers coupled together perfectly. Neither speaker was being pushed anywhere near max, and the result was an enormous amount of thump that was clean and distortion free.

There are indentations and feet on the top and bottom to allow them to stack and lock together easily. The pair felt like a single double 18" cabinet, yet I could move each piece without effort...no more 160lb cabinets to lug around! For small rooms I just use a single pair, but the rest of the time I use both pair. I'm looking forward to our first outdoor show of the year. I'm thinking my back is going to heave a sigh of relief at not having to tote massive heavy cabinets around anymore!

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    2014 I had the opportunity to tour the QSC factory in Orange County, CA. They have a 3 story room with an arch of mic's to develop and test their designs. When you hear the KW181 with a K12 on top you will hear the complete design of the music reproduced in a rich dynamic arch. Almost unbelievable except that it's QSC and designed well.

    Their manufacturing is "state of the art" using robotics for electrical assembly and really fine artisans on the assembly line. Wood, glue, screws laminates all of the finest quality. This isn't just a speaker. It's art.

    QSC ........ WOW

    By RICHARD

    from Baltimore

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    Hey there, You can't go on reviews alone to buy speakers, it is wise to go into a store and listen to the speaker. I am a mobile DJ who plays Reggae, Soca, Rap, Pop, Disco and R&B I started out with a pair of QSC Ksubs and Berinhger 215D top because i needed a system that was portable for me to carry around but did not get the bottom end from them that i was looking for. I upgraded my tops to the QSC KW122 I eventually traded the a pair of Ksubs for one of these QSC KW181 bad boys man and i was blown away by the bottom end from this sub. It is punchy, loud and has clean bass notes, you can't go wrong with this bad body. I am so freaked out and only had this 3 weeks that i am looking to buy another one in the coming weeks. Great Job QSC

    Not enough sub bass for dance music...

    By Kerry West

    from Flowery Branch, Ga

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    Started with the EV power 18 and quickly took it back. Thought with qsc and all the reviews I would step it up and try the qsc. Although it is very punchy and clean sounded bass it is not a good sub for hip hop and dubstep type music. I was hoping though cause the 6 year warranty was a BIG plus. Took it back and tried the Alto Black 18 and WOW found the right sub for dance type music. I do however think for live music, ie a live band the qsc would fit very nice.

    Works for me

    By Kenny Empson

    from Peculiar, MO

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    I purchased two floor model KW181s to replace two of the current model powered extra low JBL subs. Very happy that I did. The KW181s are extremely musical subs; the deep goes DEEP; the pole mount for the tops is very secure; the casters .... oh yeah!! If I had one complaint it would be that there is no Discreet Out like the KW Tops. Other than that, very happy!

    Best Powered Sub at Guitar Center

    By TONY LOPEZ

    from Houston, Texas

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    Tried the JBL, Cerwin Vega and all other powered subs with thier corresponding tops and most of the subs sounded distorted or as if the woofer was blown. Then the QSC KW181 was brought out and we were "Blown Away." No distortion, no rattle, just solid Punch! Then we tried the "deep" switch and we were stunned! Wow, nothing but solid pounding. Nothing that guitar center carries in powered subs compares to the QSC KW181! That is why we decided to purchase 1 QSC KW181 (will buy a second one in September) with the new EV Live X 115P tops. Best combination we heard! All this was possible because of Henry Rogers, Pro lighting and Audio Manager at the 8390 Westheimer Rd. store in Houston, Texas. So, if you ever need a "full demo" on any gear, we highly recommend you ask for Henry Rogers. We were sold on customer service and best price.

    Loud, Sexy, and Bassious

    By Brian Diener

    from Clovis, CA

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    If you are on the edge of whether or not to buy this sub, go ahead and close the other tabs with the JBLS and Mackies open because this will be your last time buying a sub, as it goes beyond everybody's expectations and then some! To start, this single sub puts out the equivalent to what 2 other subs can't. It is compatible with every powered speaker I have heard of and will make your system sound 10x louder. But the important part... How does it sound? Well, I turned it on without deep mode and my neighbors texted me and said they could feel the bass inside their own homes. To even further this, I live in a country neighborhood and the nearest house is a few hundred feet away. The second test with the KW181 I did was in my garage. The tools on the workbench were vibrating and I had to move the sub out from under my table (even though it fits great) because my laptop was vibrating up to the edge of the table and the mixer as well. I am super happy with this sub, I am currently using it with QSC K10s and the combo sounds great. No other sub gives the rumble that this one pounds into your chest. The casters are very quiet, no rattling here! Also, nobody can beat a free 6 YEAR Warrantee. Have you even owned your current sub for that long, let alone your entire sound system? QSC KW-181 Everybody!

    Not in Yorkville Level, but very close!

    By Jesse Espinoza

    from Houston, TX

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    I just purchased 2 KW181 and people these suckers hit hard. I loved them even more after I set them up with my Drive-Rack PX, they shaked my garage so hard it's not even funny. If your in the business why settle for cheap low budget gear, invest money on the good stuff like QSC and you will notice how many more customers you will get. I don't do a lot of gigs but the few private parties I do a year I get plenty of compliments on how good my setup sounds! On top I go with 2 KW122 and for my low end I have 2 KW181. I have seen many DJ's charging twice as much and playing with Beringer... Of course I laugh...

    A/B'd every sub in the store

    By David BIlodeau

    from Sugarland, TX

    Comments about QSC KW181 Powered Sub Woofer 18" 1000W:

    I went to GC to buy a sub, building my system and the open mic we host needed a little help in the low end. I went in with the intention of buying the new DXR 15" from Yamaha but I wanted to hear ALL of them. I sampled them all one after each other. Low budget, sounded exactly like low budget. Yamaha-DXR-15" and QSC-K-Sub were no where near as good as I thought they would be. The new EV's were sounding good, JBl's even better and then we got to this one. There is no comparison, it's not even close. I walked twice as far away from them as the others and still felt it. If budget is the biggest concern, go with the harbinger 18", it's the only one of the cheaper makers that even comes close. I went with them cuz I get 2-subs for less than one of these but, MAN - If I had the money; there is no question I'd buy this one.
