ABSTRACT:
A speaker enclosure for controlling an air pressure differential across a front and rear portion of a speaker cone comprising an enclosed rear chamber in communication with a primary channel having a constant cross-section, the primary channel in open communication with a convergence channel having a cross-section smaller than that of the primary channel, terminating in an orifice. In an alternate embodiment, a pair of speakers are utilized in a pair of enclosed rear chambers, each rear chamber in open communication with a primary channel of constant cross-section, each primary channel converging and joining in open communication with the convergence channel and terminating in an orifice. Additional embodiments include speaker enclosures with a front chamber adjacent a front side of the speaker to produce a pressure differential between the front chamber and the ambient air. The front chamber may have a sized opening to produce a regulated pressure flow.
