I forgot about the 3dB adjustment - and I just read in Wikipedia that the W channel is adjusted by 3dB - so to correct my guess above, I should calibrate each speaker at 71.5 + 3 = 74.5dB _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
