Err.rrh! Actually two speaker stereo IS a mess in terms of spectrum. Just compare a mono signal panned to CF with it panned to hard left or right. It's one of the things which draws attention to the speakers & spoils the illusion. One reason for the seamless performance of 1st order Ambi is that, even with just 4 rather unevenly spaced speakers, it alleviates this effect and helps make the speakers disappear. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
