It combines a 12-inch subwoofer module (KC12S), a compact column array head (KC12T), and a 32-inch pole (KC-SP32) into a single integrated system. The KC12 delivers 132 dB peak SPL with a wide 145 degree horizontal coverage pattern suited to large audiences in reverberant spaces. Available in black powder-coat finish.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe KC12 system addresses the challenge of achieving full-range, high-SPL reinforcement without the footprint and complexity of a traditional line array or ground-stack configuration. The KC12T column head uses two 4-inch midrange drivers flanking a 1-inch compression driver with QSC's LEAF waveguide to maintain controlled vertical dispersion of 35 degrees, reducing ceiling and floor reflections in difficult acoustic environments. A 12-inch woofer in the KC12S subwoofer handles low-frequency reproduction down to 40 Hz, powered by a dedicated 2000W Class D amplifier. Total system amplification reaches 3000W peak across all three amplifier channels. Built-in DSP provides up to 200 ms of signal delay, global parametric EQ, subwoofer level trim, and reverb accessible via a monochrome LCD display on the column head. Bluetooth with True Wireless Stereo (TWS) allows wireless audio streaming and stereo pairing of two KC12 systems without additional cabling. The I\/O section accommodates two combo XLR\/quarter-inch inputs (one supporting Mic\/Line Hi-Z, one with phantom power), two XLR loop-thru\/mix outputs, a 3.5 mm TRS auxiliary input, and a USB-C port providing 5V\/3A power for charging devices.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3000W Class D Amplification\u003c\/strong\u003e — 2000W to the 12-inch subwoofer, 1000W to the column array, delivering 132 dB peak SPL.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLEAF Waveguide\u003c\/strong\u003e — Controls vertical dispersion to 35 degrees to minimize room reflections in reverberant venues.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e145 Degree Horizontal Coverage\u003c\/strong\u003e — Wide audience coverage without repositioning or additional speaker clusters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated DSP\u003c\/strong\u003e — 200 ms delay, parametric EQ, subwoofer level, and reverb accessible from the front panel LCD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth with TWS\u003c\/strong\u003e — Wireless audio streaming and true wireless stereo pairing between two KC12 systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible I\/O\u003c\/strong\u003e — Dual combo XLR\/quarter-inch inputs, loop-thru and mix XLR outputs, 3.5 mm aux, USB-C charging port.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-Free Assembly\u003c\/strong\u003e — Three-component system assembles without tools;
