Abstract

A system for acoustic crosstalk cancellation which uses a loudspeaker arrangement including three loudspeakers, with the center loudspeaker set forward of the two outside loudspeakers. This arrangement increases the bandwidth in which effective cancellation is provided. The system provides a significant gain in performance over conventional crosstalk cancellation systems, which are very sensitive to the position of the listener's head.
