ABSTRACT:
A sound reproduction system includes a plurality of loudspeakers arranged in a spaced array which extends onto opposite sides of a center point. The spaced array includes a first pair of loudspeakers equally spaced apart from the center point and disposed at opposite ends of the array and a second pair of loudspeakers spaced inwardly from the first pair and also positioned on opposite sides of and equally spaced from the center point. The sound reproduction system further includes a low-pass filter having an input coupled to an output of a signal generator and an output coupled to an input of each one of the first pair of loudspeakers and a first band-pass filter having an input coupled to the output of the signal generator and an output coupled to an input of each one of the second pair of loudspeakers. The sound reproduction system may further include a third pair of loudspeakers spaced inwardly from the second pair of loudspeakers and positioned on opposite sides of and equally spaced from the center point and a second band-pass filter having an input coupled to the output of the signal generator and an output coupled to an input of each one of the third pair of loudspeakers.
