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.
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
Core Performance
- 3000-watt class-D power
- One 12-inch long-excursion subwoofer, two 4-inch midrange drivers and a 1-inch high-frequency compression driver
- 132 dB @ 1 m (peak SPL)
- Wide 145° horizontal by 35° vertical coverage for uniform sound across large audiences
Advanced Control and DSP
- Multi-Function Digital Display: system parameters including global parametric EQ, delay (up to 200 ms) and reverbBluetooth® with True Wireless Stereo (TWS)
- Presets and Scenes: library of factory presets for specific applications (DJs, Live Music, Speech) and custom Scene save/recall
Connectivity & Versatility
- 3-channel internal mixer
- Charge and Sync: USB-C port for charging mobile devices or performing firmware updates
- Flexible Deployment: Tall (with the column pole) or Short (top unit directly on the sub) deployment for floor, stage or riser use
Build & Protection
- Premium Materials: impact-resistant ABS for the top and 12 mm birch plywood for the subwoofer
- Portable Design: 60.3 lbs (27.3 kg) includes a dedicated transport tote for the column and pole sections
- 6-Year Warranty (with product registration within 30 days of purchase)
