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.
