CSW powered subwoofer

CSW subwoofer is a flat subwoofer designed for powerful bass and discreet placement.

Powerful bass

A DSP controlled, powerful 200W digital amplifier fuels the 10 inch driver with raw power. This gives powerful, deep and fast bass. The System 9 CSW Flat Sub is the perfect partner for the Sustem 9 CLS wireless speakers. Just like the CLS speaker, the CSW flat sub has a built-in high quality wireless receiver. Installation is very easy: the sub joins an existing Sonab Audio network automatically. Just plug in the power and you’re done.

Easy placement

Utilitarian and functional design in a compact flat enclosure provides flexibility in placement. Hang this flat subwoofer on walls or place it on the floor, it is just as easy. A sturdy wall bracket is enclosed.
