<p>The present invention uses a system of three loudspeakers to achieve realistic stereophonic sound reproduction. The method uses a single enclosure for the left and right speakers positioned in front in a parallel plane, with a wedge shaped enclosure with the wedge affixed at the center of the single enclosure, and containing the third speaker positioned in parallel with the single enclosure containing the left and right speakers. The invention incorporates electronic circuitry to process the left and right audio input signals. The left and right channel signals are reduced to either channel, then summed and time- delayed to the center channel speaker. The wedge shaped enclosure interrupts the usual overlap of the left and right channels and fills this area with the specially derived center channel signal, such that the listener perceives a wider sound image space.</p> |
