The RSW-12 active sub woofer provides another stunning dimension to the Silver RS sound. Its 12” C-CAM® front-firing driver, powered by a potent 500W digital amplifier, will extend the reach of all the Silver RS speakers to add the deepest drama to movies and music. The RSW-12’s lowest frequencies are controlled so expertly that even subtle effects are better defined, enhancing the RS experience with bass you can feel as well as hear.
