QSC KC12 Active 3-Way K Column Speaker System | White

The QSC KC12 is built for performers, mobile entertainers, DJs, and AV production teams who need a self-contained, high-output column system without the complexity of a traditional line array. Drawing from QSC's K-series engineering heritage, the KC12 combines a 12-inch ported subwoofer with dual 4-inch midrange drivers and a 1-inch HF compression driver into a single integrated package that goes from case to stage in minutes. The LEAF waveguide delivers uniform, controlled dispersion across a wide horizontal plane, making it practical for both wide audiences and narrow venues where pattern control matters.

On the input side, two combo XLR connectors with independent phantom power and Hi-Z options let a solo performer or small band connect microphones and instruments simultaneously, each with assignable factory presets. Bluetooth True Wireless Stereo links left and right units in low-latency sync, and the QSC Loudspeaker Control app extends real-time control from any iOS or Android device. The onboard DSP includes global parametric EQ, delay up to 200 ms, reverb, and scene recall, reducing the need for an external console at smaller events.

The system deploys with or without the included 32-inch column pole, adapting to floor, stage, or riser placement. For integrators specifying installed or semi-permanent setups, the slim column profile and available finish options keep the system visually unobtrusive. A tote bag for the top unit and pole is included, and the KC12 is backed by a 6-year warranty upon registration within 30 days of purchase.
