The Thetis 320 subwoofer has a closed cabinet, equipped with an 10” driver with half roll suspension. In order to reduce vibrations, the cabinet has been carefully designed with ingeniously placed internal reinforcements. Equipped with a class D amplifier of 250-watt RMS and 400 watt peak power, Thetis 320 produces an amazing sound for such a small enclosure. It also features a remote control and a sound level indicator on the front panel so you can adjust the subwoofer perfectly.
