ABSTRACT:
An omni-directional stereo speaker especially useful in high fidelity sound reproduction applications, comprised of a polyhedron speaker enclosure, separate speakers or drivers mounted in some or all of the faces of the polyhedron enclosure, an acoustically transparent cover or outer housing for the enclosure, and a mounting means for positioning the speaker unit away from walls or other flat reflecting surfaces so as to provide an aural stereo effect throughout a room or other limited space. The polyhedron enclosure and multiplicity of speakers therein approaches ideal spheroidal projection of the reproduced sound wave, i.e. the sound appears to be emanating from a point source, and thereby produces a realistic stereo sound image in all parts of the room.
