A system for generating at least one remote virtual speaker location in connection with at least a partial reflective environment ( 12, 12, 14 or 15 ) in combination with an audio speaker for creating multiple sound effects including a virtual sound source from the reflective environment which is perceived by a listener ( 53 ) as an original sound source, by generating a primary direct audio output by emitting audio compression waves toward a listener, and generating a secondary indirect audio output from at least one virtual speaker ( 24, 25 or 26 ) remote from the audio speakers, by emitting ultrasonic sound from at least one parametric speaker ( 20, 21 or 22 ) associated with the audio speakers and oriented toward at least one reflective environment which is remote from the audio speakers.
