A possible solution is the layout proposed by Bo-Erik Sandholm: https://mail.music.vt.edu/mailman/private/sursound/2011-May/040968.html "It uses 10 channels, it is a hexagon in the horizontal plane with a speakers at front back. The Z is handled by for speakers, placed where the 4 hexagon side speakers will end up if the Hexagon is rotated 90 degrees around a axis through the front and back hexagon speakers." -- Marc _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
