Abstract
The speaker system of the invention comprises a pair of inner and outer rightward loudspeakers and a pair of inner and outer leftward loudspeakers all of which are arranged such that their points of sound transmission are aligned on an equal vertical straight plane in front of a listener and the inner speaker of each pair is horizontally inwardly spaced from the outer speaker of the same pair a distance which is equal to the distance between the respective ears of the human head to thereby form a parallel crosstalk cancellation planes extending perpendicular to the frontal plane on which the speakers are arranged. A first crosstalk cancellation network is connected between the input circuits of the outer rightward speaker and the inner leftward speaker and a second crosstalk cancellation network is connected between the inner rightward speaker and the outer leftward speaker. Right- and left-channel binaural signals are applied to the inner right and leftward speakers, respectively.
