Abstract:
1. A speaker system for outputting at least an L-channel signal and an R-channel signal, comprising: a left speaker outputting a signal in which the R-channel signal is subtracted from the L-channel signal, wherein frequencies in the R-channel signal in the signal output by the left speaker are filtered out above a high frequency cut-off; a right speaker outputting a signal in which the L-channel signal is subtracted from the R-channel signal, and wherein frequencies in the L-channel signal in the signal output by the right speaker are filtered out above the high frequency cut-off; a center speaker outputting an un-multiplied signal in which the R-channel signal is added to the L-channel signal and frequencies in the L-channel signal and the R-channel signal are filtered out above the high frequency cut-off, and wherein the high frequency cut-off is dependent upon the size of the center speaker, right speaker and left speaker and proximity of the center speaker, right speaker and left speaker to a common point of origin; and an enclosure equipped with the left speaker, the right speaker, and the center speaker.
