Diverging Lense Port design helps reduce distortion while maximizing output

Turbosound TQ18B Description

The Turbosound TQ18B is built to extend the low-frequency performance of TQ Series systems with powerful, controlled bass response. Its reflex loaded enclosure and optimized tuning provide extended impact while maintaining accurate transient response.

Designed for both touring and installation applications, the TQ18B supports flexible cardioid configurations and electronic delay steering for improved rear rejection and pattern control. This makes it a strong choice for venues, production companies, houses of worship, and installed performance spaces that need high-output bass with better directional control.

The enclosure uses 15 mm and 18 mm plywood with a durable semi-matte black paint finish. Integral feet support secure ground stacking, while dual M20 pole mount sockets allow satellite speaker configurations.
