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.

Delivery Exclusions

PLEASE NOTE:

Some products are exceptionally large, heavy or bulky and require specialist freight services. This typically includes items such as large PA speakers, dual 15″ speaker cabinets, dual 18″ subwoofers, flight cases and other oversized or very heavy equipment.

We work hard to keep our prices as competitive as possible and, in most cases, delivery is completely covered by our standard shipping rates. However, for certain oversized items being delivered to regional or outlying areas, the actual courier cost can be significantly higher than standard deliveries. This is also owing to factors completely outside of our control (petrol costs and rising costs of delivery by courier partners)

If this applies to your order, we will always contact you before dispatch to discuss the available options. These may include:

Proceeding with a small additional freight contribution.
Collecting the order from one of our suppliers or a nearby courier depot where available.
Cancelling the order for a full refund if a suitable solution cannot be reached.

Please be assured that we only request an additional freight contribution in exceptional circumstances where the courier cost is substantially higher than normal. Our goal is always to deliver your order at the advertised price whenever possible.

If you’re unsure whether an item may be affected, you’re welcome to contact us before placing your order and we’ll gladly provide a delivery estimate.

Thank you for your understanding and ongoing support!
