QSC KC12 Active 3-Way Column PA Speaker

Delivers 3,000 room-filling watts

Despite its unassuming column-loudspeaker form factor, the KC12 offers more than enough power to tackle just about any sound reinforcement scenario. The KC12’s 3,000-watt Class D amplifier yields a robust — and amazingly undistorted — 132dB maximum peak SPL. Moreover, its 12-inch subwoofer, two high-excursion 4-inch midrange drivers, and 1-inch high-frequency compression driver span a healthy 40Hz–20kHz frequency range. Beyond that, the KC12’s QSC LEAF waveguide provides uniform 145-degree horizontal by 35-degree vertical coverage and outstanding throw, ensuring that everyone in attendance experiences superb sound — even way back in the nosebleed section.

Filled with flexible features

Here at Sweetwater, we’re amazed by how much you can accomplish with the QSC KC12 — especially for a portable loudspeaker system. For starters, it houses two combo inputs that can handle microphone, line-level, and hi-Z sources with equal assurance. Next, +48-volt phantom power accommodates your condenser mics, and thanks to per-channel factory presets, you can assign completely different applications to each input. The KC12’s cutting-edge DSP puts a global parametric EQ, subwoofer level control, up to 200ms of delay, and a reverb effect squarely at your fingertips. You also get Bluetooth connectivity with True Wireless Stereo, ensuring low-latency simultaneous pairing between your music source and the KC12’s left and right speakers.
