Turbosound M18B 18

Turbosound M18B — an 18-inch active subwoofer rated at 2,400W with a maximum SPL of 134dB, built for high-output bass reinforcement in large live sound applications.

The M18B is a self-powered 18-inch subwoofer from Turbosound designed for high-demand touring and large venue deployment. The single 18-inch high-excursion woofer is driven by a built-in amplifier rated at 2,400W continuous, producing a maximum SPL of 134dB — sufficient for large outdoor stages, arenas, and nightclub main floors. Built-in DSP provides crossover, EQ, delay, and protection functions accessible from the rear panel. The compact enclosure dimensions relative to its output power make it a practical choice where efficiency per cubic metre matters. Pairs with Turbosound full-range tops for a complete active PA system.
