Product Details

Want both power and portability? This is your PA speaker! With a 2 x 500-watt bi-amped system, the QSC KW152 powered loudspeaker is can fill a room on its own -- plus it's ideal for clusters or arrays in large-venue installations, thanks to its long-throw design and focused 60-degree pattern. It's also built to travel, with a lightweight-yet-rugged birch enclosure and comfortable cast-aluminum handles. QSC loaded the KW152 with state-of-the-art digital signal processing to help you get the most out of your 1,000 watts. Just flip the DEEP switch to hear increased low-frequency extension, without distortion or woofer over-excursion. When you consider all the connection options on the back panel of the KW152, it's simply one of the best loudspeakers available for no-compromise music and speech reproduction in large or mid-sized venues.

1,000 Watts of Continuous Power in One Smart Speaker

The KW series draws its name from QSC's kilowatt amplifier module. Like all KW powered loudspeakers, the KW152 has a Class D bi-amped design, with a 500-watt low-frequency and 500-watt high-frequency amplifier. Most two-way powered speakers have a lower-powered high-frequency amp that can easily be pushed to audible distortion -- which can stress or even destroy the speaker. But with 1,000 watts of continuous power, and 2,000 watts peak, it's nearly impossible to overdrive the KW152. Plus, this speaker is smart about power: when the KW152 doesn't sense input to its amplifier for five minutes, it automatically enters standby mode to conserve energy and extend the amp's lifespan. The instant signal is restored, the processor turns the amp back on with no noticeable audio delay. This means your system will conserve resources without you even having to think about it.

Cover the Room Consistently: Lows, Mids, and Highs

Full-range speakers like the KW152 deliver audio over the entire audible spectrum, lows to highs. But as any engineer will tell you, low frequencies naturally disperse over a wider pattern, while high frequencies tend to "beam," or deliver audio to a narrow area -- like a beam of light. Professional PA speakers use waveguide horns to disperse higher frequencies out across the audience. But typical waveguides are asymmetrical, wider than they are tall -- so they can't control the pattern all the way down to the crossover frequency. This means that key mid-range frequencies -- where most vocals and instrumental solos live and die -- end up as the least evenly dispersed. In contrast, QSC employs their Directivity Matched Transition technology to match the width and height of their speakers' symmetrical waveguides to the size of their woofers -- 15 inches, in the case of the KW152. What does this mean for you? An incredibly smooth, consistent response across the entire listening area -- even off-axis from the loudspeakers.

Long-Throw Loudspeakers: Ideal for Large Venues

Designed as "long-throw" loudspeakers, the KW152s are designed to disperse the full range of audible frequencies smoothly over a 60-degree angle. This relatively narrow 60-degree pattern means higher acoustic output over the distance necessary to fill a large venue. These speakers are great at covering long distances on their own, but one of the benefits of long-throw loudspeakers is that they make excellent modular "building blocks" for arrays or clusters. Two or more KS152s can be mounted together to cover a 120-degree or more angle, with minimal comb-filtering -- unlike short- or medium-throw speakers whose wider dispersion patterns would cause overlap. The KW152s are perfect for vertical arrays or clusters in large venues where high SPL is needed over a long distance. A KW152 also makes an excellent side-fill or drum-fill monitor on stage -- the 60-degree pattern lets you aim the speaker precisely where musicians need to hear it with less bleed, resulting in higher gain-before-feedback for your microphones on stage.

DEEP Mode: More Bass Output, Less Distortion

As a two-way speaker, the KW152 covers high frequencies up to 20 kHz with a 1.75" compression driver, while the 15" woofer is capable of reproducing low frequencies down to a growling 44 Hz. And if that's not impressive enough -- flip a switch on the back of your KW152 to activate DEEP mode: Digital Extension and Excursion Processing. More than just a low-frequency EQ boost, DEEP employs sophisticated digital signal processing to identify and limit the brief low-frequency transients that could potentially cause amplifier clipping distortion and over-excursion of your KW152's woofer cone. This virtually inaudible limiter increases the average output of bass frequencies. With DEEP processing power on board, KW152s are great on their own for streamlined setups, but they're also excellent when paired with external subwoofers like QSC's KSub or KW181. Just flip the External Sub switch to engage a 100 Hz high-pass filter -- and use those 1,000 watts even more efficiently.

Application-Specific EQ and Intrinsic Correction

In addition to DEEP for the low end, the KW152 gives you DSP control over high frequencies with application-specific EQ settings. After all, full-range music reproduction has different demands than speech reproduction. That's why all speakers in the KW series have a HF switch you can set to "Flat" for full-range music, or "Vocal Boost" for increased intelligibility and presence for speech or vocal-only reinforcement. And the KW152 also employs QSC's exclusive Intrinsic Correction EQ, which implements FIR linear phase filters more commonly found on high-end DSP processors to actively adjust the speaker's response, helping deliver consistent sound over the entire audience.

Defeatable Power LED and Locking Power Cord

Aesthetics play a large part in QSC's speaker design, and their professional, tasteful appearance puts them at home in any environment, from houses of worship to rock concerts. On the front of your KW152, you'll find a blue LED that's more than just a simple power indicator. Flip a switch to activate one of three modes: power, to indicate that the speaker is powered on; Limit, to indicate when the speaker's onboard limiter is engaged, and Off, for applications when a bright blue light isn't consistent with your event or venue's aesthetics. No matter the venue, QSC's V-LOCK power cords latch to prevent your speakers from being unintentionally unplugged -- especially useful if they're placed on a floor. These special power cords lock in with a click. And if your KW152s' cables are ever damaged or lost, standard IEC power cables will work just as well.

Multiple Input Connections: XLR, 1/4", RCA

Take a look at the back panel of your KW152 to see its many input options. Channel A accepts a microphone-level or line-level input via combination XLR-1/4" jacks, while Channel B accepts a line-level input via combination XLR-1/4" jack or a pair of RCA phono jacks. Stereo input received here will be summed to mono for output through the speaker. You'll find individual gain controls for channels A and B on the back of your KW152. There are also discrete line-level XLR outputs for channel A, channel B, and the post-gain mix of all input channels -- perfect for sending to a subwoofer.

Mounting Options for Any Venue or Mobile Rig

With its included pole socket, the KW152 is ideal for mounting above the KW181 subwoofer on a 35 mm support pole up to 36" long. And when mounting your KW152s on high wall mounts or stands, you can safely angle the speakers at a 7.5-degree angle with the built-in Tilt-Direct pole cup mount. Tilt-Direct makes it easy to focus acoustic energy on the audience -- not on reflective surfaces like the back wall, ceiling, or the front of the balcony. Want to sit your KW152 on the stage for a side-fill? How about on the floor, or directly on your subwoofer enclosure? No problem -- it's equipped with slip-resistant feet. QSC even makes it easy to suspend your speakers from the ceiling for venue installations: the KW152s are outfitted with multiple suspension points -- two on the top and bottom, and two on each side for horizontal orientation. Angling your KW152 toward the audience, vertical or horizontally, with three suspension points on the rear sides and center.

Active Loudspeakers: Simpler and Safer

Not only are active, powered speakers like the KW152 simpler to set up, they are inherently more robust than component systems with separate passive speakers and power amps. Power amps could potentially damage passive speakers if their impedance and wattage isn't properly matched, but with the KW152, there's no worry about wattages and no heavy power amps to lug around. If the KW152 were a passive speaker, it would need an enormous amplifier to safely push it. Luckily, the KW152 is an active speaker with the amp built in -- safer to operate, and simpler to install and transport. Whether you're building a high-end mobile PA, or outfitting your venue with a sound reinforcement installation, you have a choice. You can go with cheap speakers and hope for the best -- or you can step up to QSC's powerful, portable KW series.
