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).

I started with the K sub and it was ok but didnt have that punch for bass heavy southern hip hop, reggae and techno/pop. Guys I plugged in that mtuha freakin' KW181 and with the dial set at 1 'o clock the difference was clear! I listened to the Monica "Love all over me" and the bass was ridiculous.....I had a moment! I got a little choked up.

I upgraded from a Matrix 2000 to an all QSC set up and really love the tops, but this sub just does not seem to have the same bottom as my old one. I don't understand why, because they are both 18's and the QSC has more power? It must have something to do with the crossover or the frequency response. Any way, it's a great looking sub and it is much lighter than my old one. Eventually, I am going to buy another one to see if that will bring back the rumble that I remember with my ol' B-52.

    This speaker is LOUD. I love it. This speaker is worth every penny. I love the caster wheels so you don't have to pick it up at events. You can roll it around to where you need it. This speaker is like a TANK, very durable. Don't waste money on other speakers.

    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

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

      We use 4 of these KW181's in our portable church. We meet in a 500 seat auditorium and have a band with electric guitars, bass, electric kit, and synth. These KW181's deliver absolutely shirt-moving low end. Our band is drum and bass guitar driven, and we love these things. Of course, we have slightly EQ'd them to really get what we want out of the kick drum and bass guitar and have added HPF on most of the other instruments/vocals to clean up our mix. But expect to be punched in the chest. Lot's of power.

      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.

      By Kenny Empson

      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.
