QSC KC12 Active 3-Way Column Professional Speaker with Bluetooth - 3000 Watt

The QSC 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.

The QSC 3-way loudspeaker system delivers exceptional sound with a 12-inch subwoofer, dual 4-inch midrange drivers, and a 1-inch HF compression driver utilizing the proprietary QSC LEAF™ waveguide for uniform 145° H x 35° V coverage and excellent throw. It provides a powerful 132 dB peak SPL with 3000 W of energy-efficient Class D amplification featuring Power Factor Correction for low AC consumption. Equipped with two combo XLR inputs, assignable factory presets, and Bluetooth Audio with True Wireless Stereo (TWS), it supports versatile audio setups for events. A multi-function digital display offers control over EQ, presets, delay, reverb, and more.

Configured with or without its column pole, the system is ideally suited for direct deployment on a floor, stage or riser. Available in black and white, the KC12 is backed by an industry-best global 6-Year Extended Warranty, with product registration.
