Inheriting the tradition of the K series, the KC12 is a 3-way 3000W speaker system. It has the beautiful design of a column speaker while achieving acoustic performance that exceeds conventional designs. Simple and quick to install, the KC12 is ideal for solo entertainers, musicians and bands, mobile performers and DJs, video production, and fixed installation sound systems.

The highly portable KC12 system consists of a bass-reflex subwoofer with a 12-inch driver that supports up to 40Hz. The innovative design of the mid/high enclosure combines a 1-inch compression driver with QSC's proprietary LEAF? (Length-Equalized Acoustic Flare) waveguide, and two low-distortion, high-excursion 4-inch midrange drivers. This 3-way design provides excellent 145° horizontal and 35° vertical coverage for clear, natural sound at all output levels.

The system can be configured with or without column poles and is ideal for installation directly on the floor or stage.
