ABSTRACT:
A sound reproduction system for providing an enhanced stereophonic image within an enlarged listening area includes both a left and a right transducer enclosure, each enclosure having a main transducer array for receiving an audio channel signal and providing direct reproduction thereof, the main transducer array being directed into a listening area and having a dispersion profile which substantially defines the listening area, a boundary transducer for reproducing a frequency band-limited and 180 degree phase-shifted audio channel signal, the boundary transducer being directed at an angle of substantially 65 degrees with respect to the main transducer array, and an expansion transducer for reproducing a frequency band-limited audio channel signal, the expansion transducer being directed outwardly from the listening area, with the enclosure being adapted to provide structural support for the main transducer array, the boundary transducer and the expansion transducer and to maintain a predetermined angular relationship therebetween.
