Key Info
Alto TS318S is a Active 2000W 18" Powered Subwoofer that features a 12-inch driver with high-temperature, long-throw voice coil

Versatility for any room and any PA

No two rooms sound the same. One room can even sound different depending on how many audience members are there soaking up the sound. Be ready for anything with a versatile subwoofer. You can choose between six different DSP presets, altering the frequency response and crossover with the press of a button. A low frequency boost button is also included for that extra punch you need.

Stable operation, peace of mind

The Alto TS318S Active Subwoofer features a comprehensive set of protective circuitry to ensure total stability during even the most raucous live performances. With circuits to protect from electronic clipping, a signal limiter, along with thermal, and transducer overdrive protection you can have total peace of mind during performances.

As well as electronically, everything inside the subwoofer is protected physically by the robust cabinet. Constructed from braced wood composite, the enclosure is built to last. Plus, the mar-resistant splatter-spray finish looks the part no matter how heavily it is used.
