Dual diverging manifold loudspeaker system

Claim 1

A dual diverging manifold loudspeaker system comprising: a generally cubically-shaped outer horn housing being formed of a top wall, a pair of side walls, and a bottom wall, and having an open mouth and a rear wall; a generally cylindrically-shaped cavity formed of a wall member disposed within said housing, said cavity having front and back ends; said rear wall formed integrally with said housing and being disposed to substantially close the back end of said cavity, said rear wall having a generally square shape and being formed with cut-out portions disposed in each of its four corners and a central aperture; a compression driver assembly being formed of a generally cylindrical configuration and having front and back ends, said compression driver assembly converting electrical signal applied thereto into sound waves, the front end of said driver assembly having a port aligned with the central aperture of said rear wall for transmitting a planar sound wavefront thereto; an inner dome-like cap member being disposed to cover the back end of said driver assembly and to close the front end of said cavity so as to encapsulate said driver assembly completely within said housing; a back plate member being secured adjacent to the rear wall of said housing; said back plate member including first diverter means for diverting said planar sound wavefront into two diverging sound wavefronts, second diverter means for splitting said two diverging sound wavefronts into four separate planar wavefronts, and reflector means for deflecting forwardly said four separate planar wavefronts towards the open mouth of said housing; and manifold means formed by the inner surfaces of said top wall, side walls and bottom walls of said housing and said inner cap member for recombining four separate planar wavefronts back into a single composite waveform emanating from the open mouth of said housing.
