Abstract: An overhead loudspeaker system is achieved which controls and shapes the ultimate acoustical wave form produced thereby, by providing at least one loudspeaker driver, mounted in a housing or enclosure, and a uniquely constructed wave shaping and controlling member formed as an integral component of the speaker assembly. In this way, broad band, acoustical wave shaping and control is realized. In accordance with a present invention, the wave shaping/controlling member is cooperatively associated with the drivers of the loudspeaker in a way which effects the critical acoustical loading and atmospheric coupling thereof, while controlling and shaping the ultimate acoustical wave form so that a hemispherical polar coverage pattern results. In the preferred configuration, the polar coverage pattern produced by the present invention is provided across the loudspeaker system's entire power bandwidth, beginning at an approximate distance of about three times the diameter of the acoustical source.

Abstract: By providing an enclosure having an acoustically optimum size and an effective or virtual air volume for optimum performance, a loudspeaker system is realized which is able to faithfully reproduce desired input signals, particularly, lower frequencies or bass sounds, in a seemingly small or undersized enclosure. In addition, the loudspeaker system of the present invention eliminates the distortion components found in prior art systems. Preferably, the loudspeaker enclosure of the present invention is cylindrical in cross-section, comprises the loudspeaker or driver mounted at one end of the cylinder, and an inwardly extending hemispherical baffle sealingly mounted to the opposed end of the cylindrical enclosure. In addition, a plurality of holes or vents are formed in the rear baffle.

Abstract: By providing a spherically shaped housing or enclosure containing one or more drivers or speakers motors, and cooperatively mounting the housing in association with a uniquely constructed reflector, a spherical loudspeaker system is achieved which controls and shapes the ultimate acoustical waveform produced thereby. The loudspeaker system of the present invention controls and distributes the acoustical energy of the driver and housing, while shaping the acoustical energy field into a true hemispherical pattern, within the system's power bandwidth. By employing the present invention, the point of summation of the hemispherical pattern is approximately eight times the diameter of the reflector, thereby achieving the desired hemispherical polar coverage patterns.
