ABSTRACT:
High quality single or multiple channel sound dispersal is obtained through the arrangement of a plurality of similar speakers divergently mounted in an airtight frame with integral horns formed therein such that the central axis of each speaker is coaxial with a line normal to and projected from the center of each face of a polyhedron characterized by the tetrahedron, the hexahedron, the octahedron, the dodecahedron and the icosahedron. When the speakers thus arranged are excited in phase, a series of infinite acoustic baffles are created between adjacent speakers creating a series of exponential horns which disperse the sound energy as if from a point source to the walls, ceiling and floor of the listening room and then by reflection to the listener. The frame/horn component is manufactured of universal parts.
