The Turbosound TQ18B-WPC is a custom weather-resistant protective cover for the TQ18B 18" subwoofer, sized for the larger cabinet profile of the TQ series flagship sub. Nylon fabric and mesh construction protects the enclosure during outdoor use, with thick interior foam padding for transit protection. Rugged fasteners take repeated cycles in their stride, and openings provide direct access to handles, rear input panel and pole-mount hardware so deployment workflow is unchanged.
