QSC KS112 – 2000W 12-Inch Compact Powered Subwoofer
Product Overview
The QSC KS112 is a compact 2000W powered subwoofer with a 12-inch driver, designed to extend low-frequency output for K.2 Series and CP Series powered loudspeakers in portable PA systems. It delivers substantial low end from a small, easy-to-transport footprint.
Integrated DSP provides a crossover with adjustable frequency, polarity, and delay for clean alignment with satellite speakers, and multiple units can form a cardioid subwoofer array.
Product Description
The KS112 pairs a 12-inch driver with a 2000W Class-D amplifier for high output from a compact cabinet, making it well suited to mobile and small-install systems that need extended low frequency without a large enclosure.
Its integrated DSP includes a crossover with adjustable frequency, polarity, and delay so the subwoofer aligns precisely with satellite loudspeakers. For performance environments, multiple KS112 units can be configured as a cardioid subwoofer array to reduce rear energy and tighten directionality.
The KS112 integrates with QSC K.2 and CP Series full-range loudspeakers. For a larger, higher-output subwoofer, see the QSC KS118.
