QSC KS112 Powered Subwoofer

The KS112 is a single 12 inch bandpass subwoofer driven by a 2000 W peak Class D amplifier module, built to add low end to a pair of K.2 or CP tops without the bulk of an 18 inch box. It covers 41 Hz to 108 Hz (-6 dB) and reaches 128 dB peak SPL at 1 m, and at 62 lb it is light enough for one person to load without a cart.

The birch cabinet ships with built-in low-noise casters for load-in and load-out, and a top-mounted pole socket accepts a full-range top box for a compact ground-stacked system. Balanced XLR input and thru connection make it simple to add to an existing rig, and onboard limiting protects the driver at festival volumes.
