The QSC KLA181 is a self-powered 18-inch flying subwoofer designed to extend the low end of the KLA line array system for portable and installed sound. This black (BK) version delivers 1000 watts of onboard Class D power into a single 18-inch driver housed in a vented enclosure, adding deep, articulate bass under KLA12 arrays or full-range systems. Integrated M10 fly points and side bracket points let it be suspended directly in an array using the KLA rigging ecosystem, while a pole socket supports ground-stacked use. DEEP processing, GuardRail limiting, and Auto Standby help protect the driver and simplify operation.
