Abstract

Apparatus for improving the sound quality of loudspeakers, comprises a rigid shell (10) having sound absorbing material (15) on its internal surface. The shell is adapted to fit over a loudspeaker enclosure (16) and the front of the shell is open or substantially open or is covered by material which permits sound to pass therethrough in an undistorted manner.
