The 18″ direct-radiating driver is powered by a 1600W Class-D amplifier, which delivers high sound pressure levels with dynamic and musical sound reproduction of very-low frequencies. The rear panel features a pair of balanced XLR inputs, a pair of full-range XLR outputs, and a pair of high-pass XLR outputs. Additionally, the custom voicings and variable crossover make optimization for your system simple and easy.

The “built-like-a-tank” construction features a rugged wood cabinet and tough steel grille that is built to last. A great complement to the SRT Series, SRM | V-Class Series or any PA, the SR18S not only adds powerful low end, but allows for a massive increase in efficiency and output for your whole system.
