FOH Staff • New Gear • October 1, 2019

The QSC KS118 powered subwoofer packs an onboard 3,600-watt (peak) Class-D amp driving a direct-radiating 18” long-excursion woofer for impressive low-end. Intended for installations or portable applications, it’s ideal for use with QSC’s K.2 line and CP series speakers. Using two or more units, cardioid LF arrays can be created.

Features include selectable DEEP™ mode for extra LF extension, adjustable crossover and delay, rugged 18mm birch ply enclosure, four low noise casters and a M20 threaded pole receptacle that accepts a 35mm pole for easy vertical deployment with full-range loudspeakers. The 104-pound unit is 25.2 x 20.5 x 30.9” (HxWxD).

Options include the KS118-CVR transport cover; KS-LOC lock-out cover (prevents tampering with controls), SP-26 and SP-36 loudspeaker poles and a SP-16X extension pole. Street price is $1,499.
