Alto TS318S Active Subwoofer

Take the pressure off your tweeters. They weren't built for bass. The Alto TS318S Active Subwoofer was. Turn your speakers into a full PA system and get stunning live sound results every time.

With six selectable DSP output modes, you'll be equipped to take on any live sound challenge. Whatever the space you are trying to fill and whatever high frequency speakers you match it with, the TS318S is ready to fit in seamlessly.

Be ready to blow the roof off any venue. You'll have access to an impressive 1,000 watts of continuous output power, and be able to reach sound pressure levels of up to 133 dB at one meter. The audience won't know what hit them. But they'll feel the beat.

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.
