Turbosound TQ-18B18" PassiveSubwoofer

Turbosound TQ-18B — an 18-inch passive subwoofer from Turbosound's TQ series, delivering deep, high-output bass for major events, touring systems, and large venue installations.

The TQ-18B is a single 18-inch passive subwoofer designed for high-output professional applications. The single high-excursion 18-inch driver in a tuned bass-reflex enclosure provides extended low-frequency response and high SPL output for concert stages, large clubs, and outdoor events. Passive operation requires an external power amplifier — allowing system engineers to match amplification power to the venue and application precisely. The TQ-18B pairs with TQ-series full-range tops for a complete TQ system, or can be used to extend the bass response of any professional PA system. Heavy-duty touring construction throughout.
