DESC: Why hasn''t there ever been a great sounding in-wall subwoofer? We have been pondering this since the late 1990''s when we embarked on a mission to create the best in-wall subwoofer on the market. The result is an entirely new speaker system. The BassX-W10 features a proprietary 10" woofer with an inverted neodymium magnet structure. The "magnet on front" design allows for flush appearance with the wall when installed.
