ABSTRACT:
A loudspeaker system including a cabinet and at least one loudspeaker mounted on the cabinet which includes a movable speaker element for directing acoustical wave energy to the ambient atmosphere and to the interior of the cabinet. A passive radiator is mounted on the cabinet at a location spaced from the loudspeaker. A panel mounted within the cabinet interior vibrates at a free end when impacted by the acoustical wave energy from the loudspeaker. The panel generates acoustical wave energy which is directed to the passive radiator and causes the passive radiator to move and to direct sound externally of the cabinet.
