A loudspeaker apparatus is provided for producing time and phase-coherent sound waves, substantially hemispherical in shape, directed toward a listening area. The loudspeaker apparatus includes a simply-constructed, inverted speaker cone designed to produce primarily low and medium frequencies, a high frequency speaker uniquely positioned above and behind the axis of the cone to supplement the high frequencies, and absorbing material disposed inter alia at a rear portion and at the smaller end of the cone to produce the hemispherical-shaped sound waves and direct them toward the listening area. |
