The Alto Professional TS312S is a 12″ 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 12″ high-excursion woofer to produce 2000W of peak power output and a frequency response of 44 to 95 Hz (-3 dB).

The TS312S offers two XLR-1/4″ combo inputs and two XLR outputs. The integrated DSP provides six settings for interfacing with other full-range speakers, ensuring a tight and professional sound. Controls include a volume knob, a polarity reverse, extended low-frequency switch, and power switch. 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 MDF cabinet features a front port and a 1.4″ mounting socket, while the integrated and recessed carry handles simplify transportation between gigs. The Alto Professional TS312S ships with an IEC power cable.
