OVERVIEW

Full-range system with tons of low-end punch.

With proven performance and solid workmanship, the KW153 takes the next evolutionary step in wood enclosure loudspeakers. QSC engineers combined all the technical advancements of the K Series with a custom-designed, tour-grade Baltic birch cabinet for unmatched sound quality and durability that’s ready for the road.

Although smaller and lighter than previous wood enclosure models, the KW153 has power to spare and cranks out clean, tight sound at output levels that seem almost impossible for its size. This 3-way workhorse pushes out so much bottom end that your audience will swear you’re hiding subwoofers somewhere.

Under the hood you'll find an efficient, Class-D power module that pumps out 1000 watts of clean, distortion-free sound with crisp highs and deep, punchy lows. With 60 degrees of coverage, the KW153's 15-in. woofer drives low frequencies down to 33Hz making it especially useful for DJing and live reinforcement of instruments. The 6.5-in. mid-range woofer and 1.75-in. compression driver produce smooth, clear mids and crisp highs. Equally comfortable as a stage monitor, the KW153 enclosure has an angled side for use as a low-profile, horizontal wedge and a flat side for proper side-fill use.

 

Processing Technology

QSC incorporates several proprietary DSP technologies into the KW153, including Digital Extension and Excursion Processing (DEEP). DEEP allows the KW153 to deliver levels of low-frequency extension previously impossible in enclosures of this size. Another innovation is Intrinsic Correction, which uses dozens of spatially-averaged measurements mapped to the processor to deliver smooth and accurate reproduction across the entire sound field. Preventing amplifier clipping or overload is QSC's proprietary GuardRail technology, which monitors the input voltage and controls the amplifier output stage before the onset of clipping. 

 

Connectivity & Monitoring

The back of the KW153 features two XLR-combi inputs, each with its own level control. Both accommodate line-level inputs and one may be switched to microphone level sensitivity. Phono (RCA) input jacks are also included for connection of consumer electronics sources. Dual XLR outputs are provided for dual "loop-thru" XLR/M connectors and a single XLR jack is available as a summed output. All three input sources may be used at once and mixed via the two gain control knobs. In addition, user EQ controls are provided to select between different subwoofer settings. For installed applications, connecting a commonly available potentiometer to the unit's Euroblock connector allows the operator to have gain control from a remote location. Multiple KW Series units can be daisy-chained together to one centralized control. 

 

Suspension and Mounting

The KW153 may be pole-mounted, suspended, or yoke-mounted. The yoke accessory kit (not included) allows for either horizontal or vertical yoke mounting, providing a flexible means of attaching KW Series loudspeakers to a building structure or truss. When suspended deployment is required, M10 threaded inserts support vertical or horizontal suspension, while the integral pole-mount socket accommodates 35 mm speaker poles for use on a speaker stand or over a sub. The pole socket is designed so that the speaker may be angled down 7.5 degrees in order to cover the audience while keeping acoustic energy off reflective walls and ceilings.

Great Speakers, but BAD packaging

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..........

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

    A friend of mine has used 8 of the older model KW153's for several years. He usually does large to medium shows. We took his advice and bought 4. We used them with 4 double 18 subs. EVERY band that got off stage made a point to find our sound man and mention the quality of the sound. It's a winner for us! We plan on purchasing 4 more. Thanks Musicians Friend!

    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.
