Building on the success of the K Series, the KW-153 and the entire KW Series by QSC represents the next evolutionary step in wood enclosure loudspeakers. QSC's system engineers have 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 smaller and lighter than previous wood enclosure models.

High Output: The KW-153 features a QSC designed, 1000 watt (2 x 500 W continuous) Class D power module. And continuing in the K Series tradition, it is fitted with the identical high-output 1.75" HF device (full-range models) and woofers of the same high quality design. The KW-153 features a 6.5" midrange transducer.

Defined Coverage Area: Directivity Matched Transition provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.

DSP: Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a product in this category:

Intrinsic Correction, first featured in QSC's high-end line array products 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 a 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.

The KW-153 features a four-position mic / line gain switch that allows for connection of a wide variety of devices. Combo XLR and 1/4" TRS inputs accept both mic and line level input while a set of RCA phono inputs allows additional connectivity to portable MP3 players, CD players and line-level mixers.

Up to three audio sources can be mixed internally and summed to a balanced output for "daisy-chaining" of multiple units. Separate direct outputs are also provided on each channel for additional output flexibility. Control: On-board switches provide preset EQ settings. The HF setting (full-range models) can be set to VOCAL BOOST for additional presence in the critical mid-frequency area or FLAT for accurate reproduction of the incoming signal. The LF switch can be set to NORM, DEEP for additional bass extension, or EXT SUB for use with an external subwoofer. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the unit 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.

Tilt-Direct: The KW122 features a unique Tilt-Direct pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired.

Remote Gain: Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Phoenix-Style connector. In an installed application, multiple KW Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.

Premium-grade materials: KW Series is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, and a highly protective steel grille provide for ease of transport and long term durability. Integrated M10 suspension points allow for flown applications with a KW M10 KIT (sold separately).

Comments about QSC KW153 Active Loudspeaker 1000 Watt 15 Inch 3 Way:

I am a part of a cover band that just recently booked an outdoor event for a neighborhood party. I currently have 2 EV ZLX 12" speakers that I have been using for most of my gigs indoors, but I knew they wouldn't work as well outdoors. I got to try out the QSC KW153 in store and the loudness and clarity of the sound blew me away! Don't let the price get you down, you are definitely getting your money's worth with this speaker. I can't wait to use this speaker for my outdoor gig and I plan on hopefully purchasing a second one with the GC Gear Card.


Awesome sound

      Comments about QSC KW153 Active Loudspeaker 1000 Watt 15 Inch 3 Way:

      These are unbelievable speakers. Had JBL 3ways PRX735 and took them back at a $$loss but was so pleased that I did. The QSC153s blow them away and are built extremely tough where the JBLs inside housing rattled and buzzed. Not the speakers, just the cheaply built insides.
      The QSCs are high quality gear and you just feel that. Hard to explain. The sound is fantastic. We are a 5 piece band, with male and female lead vocals with an additional for 3 part harmoney. Piano {CP4} guitars, etc running through them with two Yamaha subs and everywhere we perform people rave about our PA.

      Rock solid !! Amazing speakers !

      By JOHN

      from Fairfax

      Comments about QSC KW153 Active Loudspeaker 1000 Watt 15 Inch 3 Way:

      I traded in My JBL 735's after posting a couple of times how great they were. They were great for our band at venues, but when practicing by myself after a few shows, both cabinet's housing inside the back panel rattled and vibrated. Not built well for the price. So after a strong endorsement from my salesman, Sean { who runs sound with the 153"s} I traded in the JBL's and immediately felt and heard the difference. My piano sounded amazingly better across all the keys. The high keys not as harsh, piano and organ. The vocals are just as clear and full as I have heard on any PA. What am I saying ? Better than any local band's PA that I have seen !It's hard to explain, but they feel sturdier and the back panel {although having more connections, two channels, along with locking ac input and XLR inputs !} is more consolidated where the noises from the JBL seemed to breed. We have only done one show but I feel confident in saying these are the real deal, and sound much better than the JBLs should have listened to Sean in the beginning. The bands entire sound is much improved.

      Excellent Multi Application Enclosure

      By Kenneth Willis

      from Amarillo Texas

      Comments about QSC KW153 Active Loudspeaker 1000 Watt 15 Inch 3 Way:

      I play in a Classic Rock / Modern Blues Band and we use QSC KW153s paired up with KW181 Subs...K12 monitors for front line and KW153s for side fill as well as for a drum monitor.....One KW153 per side with 2 KW181s per side is MORE THAN ENOUGH for most applications you would use them for regarding live sound reinforcement. We are planning on adding 2 more KW153s and two more KW181s in June for a large outdoor even we are doing and I have no doubt that our QSC enclosures will be rockn front of house as well as the stage just like they always do....... just simply go down to GC and demo them, plain and simple and I can assure you these speakers ROCK !

      Great Speakers, but BAD packaging

      About Me Experienced

      Comments about QSC KW153 Active Loudspeaker 1000 Watt 15 Inch 3 Way:

      These are great speakers. The speaker itself deserve a 5 stars. But the packaging that it was shipped in deserves a -10 star (if there's such thing). They had to shipped me 5 speakers total for me to have 2 acceptable ones. The Engineer that design the box, sorry, but I'd have to call him/her stupid.
      This 100 lbs speakers is being held together with a 1/2" cardboard retainer (top and bottom) without any other foam support. Any movement sideways will cause the speaker to slip out of the retainer and can scuff against anything it touches because it's rolling in the box. Not only that, any drop from the person that handle the speaker, the speaker will end up absorbing the full impact. I had to ship back the first pair due to major damages (several areas of the speakers). I was only able to use 1 out of the 2nd pair they shipped. The 5th speaker they shipped, the retainer was completely ripped. Even if the speaker looks fine cosmetically, we don't know what other damage it may have due to the impact from the shipper. This is bad, bad, bad design..... As a design Engineer myself, I would call the package is a great design for up to a K12. Anything bigger than that like a KW152 or KW153, it's trouble.

      QSC... Fix this design immediately..........
