ABSTRACT:
A device for reproducing acoustic events carried on at least two channels, in a room with at least two sidewalls, comprising, at least one first sound-radiating transducer positioned to radiate sound toward a listener with at least two second sound-radiating transducers positioned in association with the first sound-radiating transducer and for radiating sound toward the at least two sidewalls, respectively. The two channels carrying the acoustic event are supplied to the first and second transducers so that the first transducer receives both channels and each of the second transducers receives one of the two channels. The listener thus receives sound waves from the two second transducers with delay. A delay device may also be connected to the two second sound transducers for producing an additional delay in the first and second channels supplied thereto.
