QSC KW122
The QSC KW122 powered loudspeaker builds on the immensely popular QSC K12 speaker, adding a few key upgrades that make it an excellent fit for larger venues. While the KW122 and K12 are both 1000-watt 2-way 12" speakers with a 75-degree coverage angle, the KW series offers a few key upgrades not found in the QSC K series. The KW122's enclosure is made of machined birch plywood with aluminum handles, while K series enclosures are high-impact ABS molded plastic. While wood is heavier, it simply sounds better. To accommodate the KW122's larger tweeter horn, its birch wood cabinet is 26 inches tall and weighs in at 49 pounds. And of course, this speaker is packed with all the powerful DSP that QSC is known for, from DEEP and Vocal Boost processing to GuardRail limiting.
QSC's KW Speakers: Ideal for Cluster Applications
QSC's KW series speakers are made to be splayed. While K series speakers project sound in a cone-shaped pattern, KW series speakers like the KW122 project an axis-symmetric pattern with a more square cross-section. In plain English, KWs lend themselves to being grouped in a cluster of 2 or more speakers, because the square pattern edges match up with each other -- helping to blanket a large venue in consistent sound. Even if you're starting out with a single pair of KW122s, these speakers make an excellent starting point for a PA that you plan to expand in the future.
Multiple Inputs and On-Board Mixing
The QSC KW122 can simultaneously accept mic, line, and stereo RCA inputs, mix all 3 inputs within the speaker, and then send output to a second daisy-chained KW122. If you're installing a PA that will be fed by multiple mixers, the ability to connect all those inputs is a big plus.
KW Stands for Kilowatt: 1000 Watts of Class D Power
As part of QSC's KW series, the KW122 is a powered, active speaker with 1000 watts of lightweight Class D amplification. These speakers' built-in Class D power amps employ QSC's Guardrail limiter to prevent destructive clipping distortion and woofer over-excursion, while a virtually silent internal fan turns on when the amp senses high temperatures -- making the KW122 truly robust.
DEEP Mode: Bigger Bass Output, Less Distortion
To get impressive bass output from 1000 watts, the QSC KW122 employs DEEP: Digital Extension and Excursion Processing. Flip the DEEP switch on the back of your KW122, and this virtually transparent limiter kicks in to increase the average output of bass frequencies. Much more than just a low-frequency EQ boost, DEEP employs sophisticated DSP to identify and limit brief low-frequency transients while preventing distortion.
Cover the Room Consistently, from Lows to Highs
The QSC KW122 loudspeaker lets you control high frequencies with application-specific EQ settings. Set the HF switch to "Flat" for full-range music, or "Vocal Boost" for increased intelligibility and presence for speech or vocal reinforcement. In addition, QSC's Intrinsic Correction EQ implements FIR linear phase filters to adjust the speaker's response, helping deliver consistent sound over the entire audience.
