Abstract
An auxiliary bass radiator unit is disclosed for mounting in an aperture in a loudspeaker enclosure. The unit comprises a substantially rigid panel member (10) mounted on a flexable surround member (12) so as to allow the panel member, when mounted, in use, in the aperture to move in sympathy with sound waves within the enclosure. The flexable surround member includes a hinge portion (14) mounting the panel member for movement as a hinged flap. Thus, movement of the panel member in twisting and other undesirable modes is substantially avoided.
