KC12 “K Column”
Building on the legacy of the K Family, the KC12 “K Column” is a 3-way, 3000-watt loudspeaker system that combines a column aesthetic with the acoustic performance of traditional “box” systems. Easy to transport, deploy and use, it’s ideal for DJs and mobile entertainers, musicians and bands, and event production professionals.
3-Way System
3000 Watts
Fast Setup
Bluetooth® Audio
Loudspeaker Control App
6-Year Warranty
Unmatched Sound Quality
Unlike traditional column loudspeakers which use a series of small distortion-prone drivers incapable of mid- and high-frequency bandwidth, the KC12’s dual 4-inch drivers and compression driver with the QSC LEAF™ (Length-Equalized Acoustic Flare) Waveguide deliver an astounding 145° horizontal coverage area and 35° audience-directed vertical average. The result is clean and natural sound at all output levels.
