A loudspeaker has a chassis, a cone, an actuator and a sub-frame. The actuator is coupled between the chassis and the diaphragm. The sub-frame is flexibly coupled to the chassis and the diaphragm. The diaphragm is flexibly suspended from the chassis. The actuator directly drives both the diaphragm and the sub-frame through coils attached to the cone and to the sub-frame.
