The best performances need the best in sound reinforcement at all ends of the sonic spectrum. For tight, punchy low-end look no further
than the Alto Professional TS12S powered subwoofer. When added to your full-range speaker setup, the TS12S subwoofer delivers
powerful but controlled low-end presence to your PA configuration for a full and complete listening experience for the modern public
music space. With a powered subwoofer, any musical performance will take a giant leap into the realm of tonal balance with the perfect
blend of hi, mid, and extended low-end frequencies.

The Most Powerful Subwoofer Yet
Sound reinforcement needs can change from night to night but the best in the business count on reliable power at their disposal
whenever it’s needed. The TS12S is Alto Professional’s most powerful subwoofer yet, packing an incredible 2500 watts of power to make
concert halls come alive, night clubs punch and pump, houses of worship lift-up instrumental performances, and more. Thanks to its
high-efficiency Class D amplifier, TS12S adds the necessary heft and weight to any public performance for a balanced representation of
musical artistry in any environment. 

Carefully Built for Quality Performance
A structure is only as good as its foundation and your sound is no different. The TS12S subwoofer is built with reliable durability in mind to
be the anchor of your setup and the anchor of your sound. Built with superior materials, the TS12S is engineered with a premium internally
braced composite cabinet enclosure for tight, controlled sound. Enjoy all the thump and bump without the unnecessary rumbles and
rattles. The key to low-end is clear definition for impactful sonic transmission and a carefully crafted enclosure ensures a truly unbiased
sound delivery. With a premium 12-inch driver featuring a 3-inch, voice coil transducer, rest assured, the TS12S subwoofer is built to
handle the rigors of live performance whether permanently installed or as part of a traveling setup, night after night.

A Subwoofer for Any Setting
What good is a sub if it doesn’t play along nicely with the rest of your speaker setup? The TS12S is designed and engineered to fit into any
system thanks to the versatile onboard electronics switches. Quickly bounce through the User-selectable EQ tunings to enable, boost,
or bypass low end accentuation appropriately as different shows require. Use the intuitive Phase Alignment function as needed to make
sure your tops and subs perform well no matter the setting or setup. With dedicated input and output paths, seamlessly connect your
companion Alto Professional full-range loudspeakers or any other standard loudspeaker units.
