The Alto TS215S is a 15" powered subwoofer designed to provide adjustable low-frequency reinforcement for sound engineers and DJs in live stage, theater, and club setups.

Class-D amplification drives the 15" high-excursion woofer to produce 1250W of peak power output and a frequency response of 35 to 95 Hz.

The combo jack inputs allow for XLR or 1/4” connections. Balanced analog outputs are available on XLR 3-pin jacks. The built-in EQ controls include a selectable high-pass filter and a switch for extended low-frequencies, giving you the ability to tune the subwoofer to suit your preferences. LED indicators allow easy identification of the selected settings and power, signal, and limit status. The clip, thermal, and transducer overdrive protection keep the subwoofer safe.

The internally-braced plywood cabinet features a front port and a 35mm mounting socket. Integrated and recessed carry handles simply transport between gigs. The TS215S ships with an IEC power cable.
