A loudspeaker enclosure comprises an outer casing and a plurality of internal partitions which serve to define two tortuous paths extending from the rear of an opening in the front wall of the casing which receives the loudspeaker diaphragm and an outlet formed in the casing. Sound waves generated to the front of the loudspeaker diaphragm pass out of the casing through the opening in the front wall of the casing whilst sound waves generated to the rear of diaphragm are conveyed along the tortuous paths and pass out of the casing via the outlet formed therein. The outlet has a cross-sectional area which is substantially equal to the cross-sectional area of the opening in the front wall for the loudspeaker diaphragm. A deflector unit may be provided within the casing opposite the opening for the loudspeaker diaphragm so as to deflect sound waves generated to the rear of the diaphragm away from the diaphragm in a predetermined direction along the tortuous paths so that these waves are not reflected back onto the rear of the diaphragm from any part of the enclosure structure.
