Turbosound TQ-15B15" PassiveSubwoofer

Turbosound TQ-15B — a 15-inch passive subwoofer from Turbosound's TQ series, delivering controlled deep bass for live sound reinforcement and touring applications.

The TQ-15B is the 15-inch variant in the Turbosound TQ subwoofer range, sitting below the TQ-18B in output but offering a more compact and lighter alternative for installations where the 18-inch version is impractical. The single high-excursion 15-inch driver in a tuned bass-reflex enclosure provides extended low-frequency response and solid SPL for mid-size venues, club stages, and corporate events. Passive operation pairs with any suitably rated power amplifier, giving system engineers flexibility in amplifier selection. Pairs with TQ-series full-range tops or any compatible PA system requiring additional bass extension.
