Alto Professional TS15S 15-inch Active Subwoofer

2,500 watts of thunderous low end

Armed with 2,500 muscular watts of Class D power, the TS15S is one of the most formidable active subwoofers in its class. The TS15S comes loaded with a premium 15-inch driver featuring a 3-inch high-temperature voice coil, yielding thunderous low end all the way down to 36Hz. Show after show, night after night, the TS15S is engineered to elevate the low-frequency output of any live performance in permanent install scenarios and mobile setups alike.

Brimming with high-tech features

Here at Prime Audio Works, we’re impressed with how much functionality Alto Professional packed into the TS15S. For starters, it includes two combo inputs that accommodate XLR and 1/4-inch connectors. You also get two balanced XLR line outputs and two XLR thru ports for linking. User-selectable EQ tunings automatically tailor the TS15S for various applications. A phase alignment selector switch rounds out this sub’s outstanding feature set.

Engineered to withstand the rigors of live performance

The TS15S is a powered subwoofer built to last. It’s housed in a near-bulletproof, internally braced, front-ported MDF cabinet with an integrated 36mm pole socket for simplified speaker installation. Its mark-resistant splatter-spray finish will continue to look great, even after several seasons of punishing use. You also get electronic clip, thermal, and transducer overdrive protection to safeguard your sub against all sorts of road-borne hazards.
