ABSTRACT:
In accordance with the invention, there is provided a tapered slot coupler combined with a loudspeaker for providing a high degree of uniform angular sound distribution in the horizontal plane, and a sharp cut-off above the horizontal plane through the coupler-speaker combination. It also sends a greater amount of sound energy to the furthest point of the domain and diminishing energy in direction to the interior of the domain as one comes closer and closer to the sound source. A sound reproduction system cooperating with the coupler-speaker combination has a receiving domain for receiving the sound, a perimeter defining the domain, and a plurality of tapered slot high and medium frequency coupler-speakers disposed proximal to the perimeter facing the domain, and a plurality of low frequency loudspeakers also disposed along the perimeter facing the domain, wherein the high/medium frequency loudspeakers are of the tapered slot coupler-speaker combination type. The invention includes sound-energy generating apparatus operative for feeding sound energy to the speakers.
