The Truesonic TS212S powered subwoofer also offers dual XLR/TRS combo inputs, an internal active crossover, and is housed in rugged, compact, internally-braced front-ported plywood cabinet with durable metal recessed handles making it as solid as a rock, yet completely portable.

The party piece of the Truesonic TS212S is the powerful 12" woofer with 2.5" voice coil and double ventilation. This enables the Truesonic TS212S to dish out as much precise, pure power as you need.
