Quality components

The TS315S doesn't waste energy. So you won't have to either. Constructed from a dense wood-composite, the TS315S Sub is ultra-strong and resonant-free. Meaning your sound isn't wasted as cabinet vibration. Giving you the sonic impact you need.

A sub needs to blend seamlessly into a speaker configuration. And that's exactly what the TS315S does. With six selectable output modes, this sub has enough DSP to be tailored to any arrangement.
