About the QSC KW Series
The QSC KW Series represents an evolutionary step beyond previous wood enclosure loudspeaker designs, combining the electronic attributes of the K Series with smaller, lighter birch cabinets. Each model features 1000-watt Class D power (2 x 500 W continuous), an onboard mixer with two combo XLR and quarter-inch inputs plus stereo RCA inputs, two direct channel outputs and a single summed balanced output. DSP includes QSC's DEEP and Intrinsic Correction technologies, while DMT (Directivity Matched Transition) ensures uniform sound field coverage. The KW122 delivers 131 dB peak SPL with 75-degree conical coverage and doubles as a floor monitor wedge, while the KW152 offers 133 dB peak SPL with 60-degree conical coverage. Both models feature tour-grade 16-gauge steel grilles, ergonomic handles, 35 mm pole sockets with Tilt-Direct, and M10 rigging points for suspended installation.
QSC KW Series — buyer FAQs
What is the QSC KW Series and how does it differ from the K Series?
The QSC KW Series is a line of powered wood enclosure loudspeakers that builds on the K Series by carrying over the same electronic attributes while using smaller, lighter birch cabinets than previous wood enclosure designs. The result is a speaker that retains the K Series electronics, including 1000-watt Class D amplification and onboard DSP, in a more portable wooden cabinet format.
Who makes the KW Series and where does it fit in the QSC range?
QSC is an American audio, video and control manufacturer known for professional power amplifiers, loudspeakers and the Q-SYS platform. The KW Series sits above entry-level offerings as a wood enclosure line aimed at professional live sound, bridging the portability of the K Series with the acoustic character of a birch cabinet build.
What onboard mixing and connectivity does the QSC KW Series provide?
Each KW Series model includes an onboard mixer with two combination XLR and quarter-inch inputs, stereo RCA inputs covering three audio input sources, two direct channel outputs and a single summed balanced output. This lets the speaker function as a standalone mix point without an external mixer, useful for smaller setups or monitor applications.
What are the key differences between the KW122 and KW152 models?
The KW122 uses a 12-inch woofer with 75-degree conical DMT coverage and reaches 131 dB peak SPL, and it also functions as a floor monitor wedge. The KW152 uses a 15-inch woofer with 60-degree conical DMT coverage and a higher 133 dB peak SPL. Both share the 1000-watt Class D power module and identical connectivity and DSP features.
What should I check when buying a used QSC KW Series speaker?
Confirm which model you are buying, the KW122 or KW152, as coverage angle and SPL differ between them. Check that the onboard mixer inputs, DSP functions and both power channels are working, and inspect the birch enclosure and tour-grade steel grille for damage. Used units may or may not include a pole socket or flight case, so confirm what is in the package.
