A false back 11 co-operates with sides 4, 5, back 6, and inclined members 15, 16 spanning the corners of the housing, to define chambers 12, 13, 14, constituting a labyrinth to which access is afforded through apertures 15<1>, 16<1> in members 15, 16 for sound radiated rearwardly from the loudspeaker cone. Baffles 17 having staggered openings may be provided in the chamber 12 behind the false back 11.
