The D10SUB ceiling mount subwoofer provides powerful, high impact bass response intended to augment any combination of C or D SERIES full-range models. By including a complement of D10SUB's into a distributed system, musical results that equal or exceed that of much larger and more costly surface-mount systems can readily be achieved. The D10SUB's clean, clear bass response provides a compelling attraction for shoppers in a retail environment, and a memorable experience for bar, pub and restaurant patrons.</p>
