ABSTRACT:
A speaker enclosure with a multiplicity of sound-openings in which the back sound pressure from a plurality of front radiating speaker-units mounted in a vertical row on a baffle board, is completely divided at the back of the speaker-units by a centrally located dividing board. Reflecting boards at the corners of the sound paths and left and right sound pressure guide boards fixed to the edges of the baffle board effectively guide the back sound pressure through left and right front openings formed between the guide boards and the sides of the enclosure. The front openings are adjusted by hinged volume and tone control boards to effectively combine the sound pressure radiated from the front-side of the speaker-units with that from the back-side.
