Details

The Thetis 280 was developed with two goals: to create a high performance, musical yet extremely compact subwoofer. The bass must be fast, clean and blend perfectly to any soundtrack.

This subwoofer instantly impresses with its speed and its agility. It will fit perfectly to strengthen bass in a stereo system and in a small home theater installation. The Thetis 280 integrates an 8 inches downward firing woofer with a half roll suspension and a very stiff diaphragm to avoid and distortion.

It includes a built-in 150 watts Rms class D amplifier that can reach up to 250 Watts at maximum peak power, providing impressive power and impact for a subwoofer of this size. The Thetis cabinet has been carefully designed to cancel any vibrations or disturbances to provide a truly involving musical experience.

An included remote control and a LED display at the front of the cabinet helps to finetune the volume output of the subwoofer.
