  • Acoustic crosstalk cancellation system
    Patent number: 6424719
    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.
