QSC KS112 12" Active Subwoofer Portable Bass

The QSC KS112 is an active subwoofer designed around a single principle: deliver professional-grade bass in the smallest possible package. Its single 12-inch driver is housed in a bandpass cabinet configuration that maximizes low-frequency output efficiency, allowing the compact enclosure to produce bass performance that belies its size. The internal 2000-watt peak Class D amplifier provides clean, controlled power while remaining energy-efficient — a critical factor for portable setups where power distribution may be limited. QSC's Intrinsic Correction DSP is built into the amplifier module, providing factory-tuned frequency response correction, phase alignment, and loudspeaker management without the need for external processing hardware.

The cabinet is constructed from premium birch plywood, a material chosen for its combination of structural rigidity, resonance damping, and resistance to the wear of regular transport. Integrated low-noise casters allow a single operator to roll the KS112 into position without a hand truck, and two M20 threaded pole receptacles — mountable vertically or horizontally — provide a stable, wobble-free connection point for speaker poles. For permanent installations or events where equipment security is a concern, the optional KS-LOC cover locks down the rear control panel to prevent unauthorized adjustment. The KS112 is purpose-built for mobile entertainers, AV integrators, and sound companies that need reliable, punchy bass from a subwoofer they can fit in a sedan trunk or tuck under a stage riser.
