The Alto Truesonic TS215S Powered Subwoofer makes an excellent companion for your Alto Truesonic full range speakers. The 650 watts of continuous power drives a 15" speaker capable of delivering thunderous lows between 35 and 95Hz, but remains precise in its delivery.

Power with Precision

Packed with 625 watts of continuous class D amplification, the Alto Truesonic TS215S Powered Subwoofer delivers massive bottom end when you need it most. Giving you a substantial amount of power over lower frequencies gives you more depth to mix with and the TS215S delivers this effectively, economically and remains a very popular choice for sound engineers and bands all over the world.

The frequency range and crossover of the Truesonic TS215S has been tuned to provide smooth, low-end sound production in the 35Hz-95Hz range. The Truesonic TS215S 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 TS215S is the powerful 15" woofer with 3" voice coil and double ventilation. This enables the Truesonic TS215S to dish out as much precise, pure power as you need.
