The QSC KLA181 is a self-powered 18-inch flying subwoofer that adds deep low-frequency support to the KLA line array system. This white (WH) version carries the same 1000-watt Class D power module and single 18-inch vented driver as the standard model, in a white cabinet that visually matches KLA12-WH arrays for stage and installed applications. Integrated M10 fly points and side bracket points allow it to be suspended within a KLA array, while a pole socket supports ground-stacked setups. DEEP processing, GuardRail limiting, and Auto Standby protect the system and streamline operation.
