QSC KC 12

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 and white, the KC12 is backed by an industry-best global 6-Year Extended Warranty, with product registration.
