The powered heart of the QSC KC12 active 3-way column system, the QSC KC12S is a ported 12-inch subwoofer that houses the system's 3000 W Class D amplifier, DSP, and 3-channel mixer. Its long-excursion 12-inch driver extends down to 40 Hz for rich, articulate low end.

The rear panel provides two combo XLR mic/line inputs with assignable presets, Bluetooth audio with True Wireless Stereo (TWS), stereo aux, USB-C, and a backlit display with rotary navigation. The KC12T mid-high column and KC-SP32 pole connect directly on top via D-shaped fittings for fast, cable-free deployment on floor, stage, or riser.

Note: The KC12S is the powered base component of the white KC12 system; pair it with the KC12T column for a complete loudspeaker system.
