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, available in black and white, is ideal for solo entertainers, musicians and bands, mobile entertainers and DJs, AV productions and static installations.

Using a 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 KC12 is ideally suited for direct deployment on a floor, stage or riser, and is backed by an industry-best global 6-Year Extended Warranty, with product registration.

QSC KC12-BK Features

• 3-way loudspeaker system featuring a 12-inch (305 mm) subwoofer, two high-excursion 4-inch (102 mm) midrange drivers and a 1-inch (25.4 mm) HF compression driver combined with the proprietary QSC LEAF™ waveguide.
• Very high, undistorted 132 dB maximum peak SPL.
• Energy-efficient Class D amplification featuring 3000 W of total peak power with Power Factor Correction and extremely low AC consumption.
• Innovative QSC LEAF™ (Length-Equalized Acoustic Flare) waveguide provides defined, uniform coverage (145° H x 35° V) and excellent throw.
• Two combo XLR inputs (Mic/Line/Hi-Z and Mic/Line/+48 V), with independent, assignable Factory Presets for each input, perfect for small events where two microphones are needed for different use.
• Multi-function digital display for control and selection of loudspeaker functions including Global Parametric EQ, Subwoofer level, Presets and Scenes, Bluetooth® configuration, Delay (200 ms) or Reverb.
• Bluetooth Audio featuring True Wireless Stereo (TWS), which ensures low-latency pairing between music source and both left and right loudspeakers, simultaneously.
• Configured with or without its column pole, the system is ideally suited for direct deployments on a floor, stage or riser.
• Available in black finishes.
• Industry-best global 6-Year Extended Warranty with product registration.
• The KC12 features dual 4-inch drivers optimized to handle low-midrange frequencies down to the crossover point with the 12-inch subwoofer.
• A dedicated 1-inch (25.4 mm) HF compression driver, paired with the innovative QSC LEAF™ waveguide, delivers precise, uniform coverage (145 H x 3° V) and exceptional performance beyond 15 kHz, with superior high-frequency sensitivity and impressive throw.
• The combination of the compression driver and dual 4-inch drivers ensures high SPL handling while reducing harmonic distortion by operating each driver within a defined bandwidth.
