The QSC KS112 is a compact, powered subwoofer for mobile entertainers, AV production and rental professionals, as well as modestly-sized performance venues. The subwoofer features a 2000W Class-D amplifier that powers the 12″, long-excursion woofer in a 6th order band-pass design with a frequency response of 41 to 108 Hz (-6 dB) and a peak SPL of 128 dB (@ 3.3′).

The subwoofer can be deployed in a vertical or horizontal position and features M20 speaker pole fittings in either position, while the 15mm Baltic birch enclosure features a rugged paint designed for long-life and lasting durability. The rear panel offers an LCD control module with variable crossover and savable and recallable scenes, as well as Intrinsic Correction tuning and loudspeaker management. There are two combo XLR-1/4″ inputs and two XLR “Pass-Thru” outputs. The KS112 ships with a locking IEC power cord and four low-noise, heavy-duty casters.
