QSC LS118 | 18-inch Powered Subwoofer W/ Dante

LS118

4000W Next-Generation Intelligent Active 18" Subwoofer - Black

Featuring a combination of leading-edge innovation, refined engineering, and unparalleled ease of use in an easy-to-deploy package, the QSC LS118 is a next-generation, intelligent, active subwoofer that's designed to complement the LA 108 and LA 112 line-array loudspeakers. The subwoofer is well suited for live venues, fixed installations, mobile entertainers, AV rental, and event production.

The LS118 features a QSC Acoustic Linear Phase (ALP) design, which permits the effortless combination and coherent deployment of QSC loudspeakers within the same sound system. The subwoofer also provides daisy-chain connections for analog, networked digital audio (Dante and Q-Sys) and AC power (PowerCON TRUE1). Two or more LS118 can be configured in a cardioid arrangement, maximizing low-frequency output in front while minimizing unwanted energy around the sides and rear of the system. The LS118 includes four 4" casters and a powerCON TRUE 1 power cord.
