“The cabinet of the SB13-Ultra subwoofer is constructed of MDF (medium density fiberboard) and contains a large window brace internally which the motor of the driver fits into. This brace stiffens the top bottom and sides of the cabinet and also helps support the heavy driver motor and relieves stress on the front baffle and driver mounting area. ”
