ABSTRACT:
An acoustic loudspeaker is mounted within a curved reflecting enclosure. Openings through the enclosure allow sound vibrations from the front of the speaker to emerge from the enclosure. A port in the enclosure, spaced away from the openings allow vibrations from the rear of the speaker to emerge from the enclosure. The inside of the enclosure is shaped to direct the desired vibrations through the port. A second embodiment has two speakers and two ports non-interferingly mounted in a single reflecting enclosure.
