When we first experienced QSC's super-powerful and amazingly portable active K-series PA speakers, we were blown away, to say the least. Now, here's your chance to change the way you look at live sound; plug into the 1,000-watt KW153 and prepare to be amazed! QSC packed a 2 x 500-watt, Class D powerplant into this speaker's premium birch enclosure, and very effective onboard DSP lets you get the absolute maximum out of its low-, mid-, and high-frequency drivers. You'll love the connection and control options on the KW153's back panel. You'll also love the fact that this loudspeaker is built for the long haul. Plug into the KW153 and you'll be a believer!
If it's power you're after, then this is your loudspeaker. QSC built the KW153 to give you big, clean, room-filling performance, to the tune of 1,000 watts. And, thanks to the Class D design, this speaker won't break your back when it's time to set up or tear down! One amp puts 500 watts through the low-frequency 15" driver, while the 6.5" mid driver and the 1/75" HF driver share power from the other 500-watt amp. The result? Big, clean sound across all frequencies! The KW153 also puts an array of connection options conveniently at hand. The back panel gives you mic, line, and even RCA inputs plus gain controls, right where you need them. You can even mix up to three audio sources internally and daisy chain to another speaker, via the balanced output.
QSC built DSP right into the KW153, so you get the absolute most out of this speaker's formidable wattage. Intrinsic Correction adjusts time, frequency, and amplitude response to give you amazing performance across all frequencies. Guardrail protection keeps the amplifier safe from overloads and minimizes clipping. Hit the DEEP switch and hear just how big this speaker can sound. This isn't just a series of filters and limiters thrown in to enhance the sound; this DSP makes an already outstanding speaker incredibly efficient and perfect for any room.
You know that a well-made loudspeaker is only as good as the ruggedness of its enclosure. After all, if it can't take the rigors of the road, then what good is it? That's why QSC made the KW153 extremely tough. You get premium-grade Baltic birch cabinet construction, a tough steel grille, cast-aluminum side handles, and even integrated M10 suspension points for flown installation.
Combo XLR and 1/4" TRS inputs accept both mic- and line-level input while a set of RCA phono inputs (except KSub) allow additional connectivity to portable MP3 players, CD players and line-level mixers. As many as 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.
Deep
Sophisticated digital signal processing provides greater low-frequency extension while precisely protecting the woofer from over-excursion.
DMT
Directivity Matched Transition matches the HF coverage angle to the natural coverage angle of the woofer for uniform frequency response over the entire coverage area.
Axisymmetric Wave Guide
The axisymmetric wave guide eliminates the phase distortions of typical asymmetric horns for more natural reproduction.
1000 Watts
The same state-of-the-art, light-weight Class D amplifier module powers all the K and KW Series models.
EQ Modes
Optimize for a specific application with the simple flip of a switch.
Energy Management
Automatic standby mode conserves energy and extends the life of the loudspeaker.
LED Operation
Switch selectable: On (power indicator) / off (dark) / limit (limiter indication)
Remote Control
Easy-to-use remote gain control is ideal for installed applications.
Pro Appearance
Sleek lines and a full grille for a more professional look than other molded loudspeakers.
Locking IEC Power Cable
Help prevent unexpected interruptions.
Connectivity
Mic/line and RCA inputs along with onboard mixing controls allow greater flexibility.
Tilt-Direct Pole Mount
A simple turn of the dial is all it takes to alter the vertical directivity by 7.5 degrees.
Suspension and Mounting
With integrated threaded inserts, KW Series is equally at home in mounted or flown applications.
Threaded Pole
The KW181 subwoofer comes with a threaded pole for a snug, safe fit.
Intrinsic Correction
An exclusive QSC process that applies extensive acoustic measurements to noticeably improve audio quality.
Class D
Higher efficiency produces less heat and more sonic performance with lower overall current draw.
Protections
QSC's Guardrail™ technology protect your loudspeakers from overexcursion. On-demand cooling fan and thermal limiting prevent overheated electronics.
