The CWS10 subwoofer is the first product of its type: a high-performance fully enclosed in-wall subwoofer. A pair of 10” woofers of unique design provides stand-alone subwoofer performance in a wall-mounted enclosure less than 4 inches deep. The CWS10 can be used with any of our in-wall systems but is perfectly matched to the similarly constructed CW600E In-Wall Speaker and CW800E In-Wall Speaker high-performance in-walls.
