The Story
QSC LS118 4,000-watt 18-inch Active Subwoofer
The QSC LS118 is a next-gen active subwoofer that packs intelligent, leading-edge digital processing into a lightweight, easy-to-deploy package. This 4,000-watt peak sub boasts a superb-sounding long-excursion cone driver, yielding an impressive low-frequency performance and distortion-free playback at high SPLs. You get selectable omnidirectional and cardioid radiation modes, along with a Deep mode for extreme low-frequency extension. Beyond that, the LS118's ALP design and onboard Dante networking guarantee outstanding coherence and lock-tight interoperability with other Dante-compatible audio equipment. You also get a rugged wooden enclosure with a durable polyurea coating, four low-noise, heavy-duty casters for effortless portability, and a generous range of deployment options. Moreover, QSC's SysNav app enables you to design, configure, control, and monitor your entire array with unprecedented simplicity. A universal power supply with a low 3.6amp power consumption rounds out the LS118's ample feature set. The QSC LS118 makes a perfect complement to the company's LA108 and LS118 active line array loudspeakers.
