A speaker enclosure has three chambers (112, 114, 116) sub-divided from one other, two or three chambers being ported by their own separate acoustic port (132, 134, 136) to the ambient. An electro-acoustic transducer (130) is mounted in communication with two of the chambers, and the third chamber is isolated from the transducer (130) except for an acoustic port (138) communicating between the third chamber and one of the other two chambers.
