Building on the legacy of the World of K portfolio, the KC12 is a 3-way, 3000-watt loudspeaker system encompassing the visual aesthetic of a column loudspeaker, while surpassing the acoustic performance of conventional designs. Simple and rapid to deploy, the elegant KC12 is ideal for solo entertainers, musicians and bands, mobile entertainers and DJs, AV productions and static installations.
The highly portable KC12 system consists of a ported subwoofer, housing a 12-inch driver extending down to 40 Hz. The groundbreaking design of the mid/high enclosure features a 1-inch compression driver combined with the innovative QSC LEAF™ (Length-Equalized Acoustic Flare) waveguide, as well as two high-excursion 4-inch midrange drivers. Thanks to this 3-way design, the system provides an outstanding full-range horizontal coverage of 145 degree, and 35 degrees of audience-directed vertical coverage, with clean and natural sound at all output levels.
Configured with or without its column pole, the system is ideally suited for direct deployment on a floor, stage or riser. Available in black.
3-way loudspeaker system featuring a 12-inch (305 mm) subwoofer, two high-excursion 4-inch (102 mm) midrange drivers and a 1-inch (25.4 mm) HF compression driver combined with the proprietary QSC LEAF waveguide.
Very high, undistorted 132 dB maximum peak SPL.
Energy-efficient Class D amplification featuring 3000 W of total peak power with Power Factor Correction and extremely low AC consumption
Innovative QSC LEAF (Length-Equalized Acoustic Flare) waveguide provides defined, uniform coverage (145° H x 35° V) and excellent throw.
Two combo XLR inputs (Mic/Line/Hi-Z and Mic/Line/+48 V), with independent, assignable Factory Presets for each input, perfect for small events where two microphones are needed for different use.
Multi-function digital display for control and selection of loudspeaker functions including Global Parametric EQ, Subwoofer level, Presets and Scenes, Bluetooth configuration, Delay (200 ms) or Reverb.
Bluetooth Audio featuring True Wireless Stereo (TWS), which ensures low-latency pairing between music source and both left and right loudspeakers, simultaneously.
Configured with or without its column pole, the system is ideally suited for direct deployments on a floor, stage or riser.
Available in black finish.
