Title: Bass sound projection systems

Abstract: A bass sound projection system comprises a cabinet containing at least one bass loudspeaker operating into a sound channel. The sound channel converges forwardly, relative to the direction of propagation of sound waves, of the loudspeaker to a throat and then diverges forwardly, relative to the direction of propagation of sound waves, of the throat to an acoustically open front end of the cabinet. The system may include a further bass loudspeaker and sound channel arranged as a mirror image of the first bass loudspeaker and sound channel, and the or each sound channel may be folded.
