The QSC LS118 is a networked, self-powered 18-inch subwoofer in QSC's L Class line array system. It pairs a long-excursion 18-inch driver with a 4,000-watt Class D amplifier to deliver deep, high-output low end that anchors LA108 and LA112 arrays. Designed for touring, rental and installed use, it can be ground-stacked with L Class tops on a pole or arrayed with additional subs, and its onboard networking integrates with QSC's system control and DSP. It suits production companies, houses of worship and venues needing substantial, controllable bass.
