Abstract A bass-reflex type speaker system having a cabinet including a front baffle board, a back panel and two side panels and a speaker mounted on the front panel. A port is disposed in either the back panel or in one of the side panels and a duct is in communication with the port. The back panel may be flat or have a generally triangular cross-sectional configuration where the apex of the triangle is directed toward the speaker. Further, the speaker may be positioned in the approximate center of the front baffle board and the port positioned at the apex of the back panel. A beam may be provided extending across and spaced from the port, the beam having a triangular shaped tip directed toward and spaced from the port.
In a bass-reflex type speaker system having a cabinet including a front baffle board, a back panel and two side panels and a speaker mounted on the front panel, the improvement comprising the back panel having a generally triangular cross-sectional configuration where the apex of the triangle is directed toward the speaker; and a port disposed in said back panel at the apex of the triangle and a duct in communication with said port where the port is positioned directly behind the speaker.
