QSC KW153 Three-Way Active PA Loudspeaker
The QSC KW153 15-inch powered loudspeaker delivers on all of these fronts while remaining fully transportable for bands and DJs alike, thanks to its lightweight Class D amplifier and comfortable, ergonomic handles. But its trapezoidal design and M10 rigging points also make it the perfect choice for permanent installations.
In designing the KW Series, QSC's engineers have created what can only be described as the next evolutionary step in wood enclosure loudspeakers. All models in the line are smaller, significantly lighter, and more rugged than previous wood enclosure loudspeakers. The KW153 represents the pinnacle of this series, packing a huge punch into a surprisingly manageable package.

QSC first made its name as one of the industry’s premier power amplifier manufacturers. So it should come as no surprise that the KW153 features a super-clean, ultra-lightweight, highly-reliable, 1000 watt (2 x 500) Class D power module. You’ll enjoy peace of mind knowing your speakers are driven by amplifiers from a legendary company with 50 years of experience in the field.
Speaking of Excellence
In addition to the 1.75 inch diaphragm compression driver that all KW Series speakers feature, the QSC KW153 sports a 15 inch woofer and a 6.5 inch midrange transducer. This 3-way configuration not only takes some of the stress off each of the individual components, it also results in a much smoother and wider overall frequency response — 35 Hz to 18 kHz at -6 dB and 33 Hz to 20 kHz at -10 dB.
We’ve Got You Covered
All the power and frequency response in the world won’t really help your show if the majority of your audience is sitting outside the “sweet spot”. That’s where QSC’s proprietary Directivity Matched Transition (DMT) comes into play. DMT duplicates LF and HF dispersion across the entire listening area, effectively eliminating dead zones and hot spots. With the KW153, there is no longer a bad seat in the house.
The KW153’s rear panel offers such a wide variety of input jacks and gain controls that it actually qualifies as a mixer. Here you’ll find Mic/Line Input A and Line Input B, each equipped with a combo XLR/Balanced TRS 1/4” jack, a Gain control, and a Signal LED. Mic/Line Input A has a rotary four-stage gain control ranging from 0dB to -36dB, allowing you to actually patch a balanced microphone directly to the KW153. Line Input B also features a stereo pair of RCA jacks for connecting audio devices such as an MP3 player, laptop, tablet, unbalanced external mixer, and more. Both channels have passive Line Outs on XLR jack, but there’s a main Post Gain - Mix Line Out, also on XLR.
Preset EQs and Filters
The rear panel of the KW153 also features switches for selecting preset EQ settings. The HF switch offers Flat and Vocal Boost settings. Flat offers you the highest possible accuracy, while Vocal Boost adds the midrange presence that is so critical for vocal clarity.
Set the LF switch to NORM for no effect, or choose DEEP for additional bass extension if you’re not using a subwoofer. If you do have a subwoofer (for those looking for a sub to include, the QSC KW181 works wonders!), selecting EXT SUB cuts the amount of low frequencies the KW153 produces so your sub can handle the heavy lifting.
There’s also a LED switch on the rear panel that selects what mode the front-mounted LED indicates. Choose from POWER to tell at a glance if the KW153 is powered on; LIMIT to monitor when the clip limiter circuit has been engaged; or OFF for situations where you don’t want the LED to be illuminated at all.
Remote Gain Control
Useful for install situations where you may need to control the gain of multiple daisy-chained KW Series speakers remotely, the KW153 has a Phoenix-style connector for integrating an external potentiometer. There’s also an Auto-Standby mode that kicks in after 5 minutes of inactivity.
The KW153 is designed to endure the rigors of the road for years to come. Its cabinetry is constructed of premium-grade Baltic birch and finished with a chip and scratch-resistant textured paint. You’ll find the cast aluminum handles to be comfortable and ergonomic, despite their low weight. The black powder-coated 16 gauge steel grille is highly effective at protecting the KW153’s transducers. There’s even a wobble-free connection for the included threaded speaker pole.
QSC's Guardrail™ technology protects your KW153’s woofer from over excursion — the primary cause of voice coil burnout. There’s also an on-demand cooling fan on the rear panel and internal thermal limiting circuitry to prevent the electronics from overheating.
