DEEP extends low-frequency output, while a cardioid preset supports directional configurations with two or more units.\u003c\/p\u003e\n\u003cp\u003eDJs, bands, mobile entertainers, and production crews can use this active subwoofer for event sound reinforcement. It also serves houses of worship and small installations requiring dedicated bass support. For buyers building a mobile DJ speaker system or expanding a live band PA, rear-panel adjustments simplify setup. Wireless access through the QSC Loudspeaker Control app allows settings changes from a phone.\u003c\/p\u003e\n\u003cp\u003eLocking combination inputs accept XLR or 1\/4-inch connections, and separate outputs accommodate signal routing to additional equipment. The painted birch plywood cabinet includes an M20 threaded socket for compatible loudspeaker poles. Optional casters support transport between venues.
