The compact Blackline S15+ sub-bass system has been designed to be used with Blackline F12+ or F15+ full-range systems to extend and increase the total low-frequency output power. The S15+ provides good bass punch from a new, long-excursion, 15” (380mm)/4” (100mm) voice coil driver with a water-resistant cone and triple-roll surround.
The S15+ features substantial birch ply construction and large-area porting to reduce air noise. It can operate in passive add-on mode using its internal switchable passive network or may be used actively with an M3+ or DX1.5 controller. In the active configuration, the controller will provide crossover, EQ, and limiter functions for the S15+ and F10+/F12+ combination.
The S15+ is provided with a top hat fitting that can be used to pole mount an F10+ or F12+ above the enclosure.
