You should also try adjusting using the Avia test tones (at 85db), your results may be different. I have also noticed a difference between different setup discs as well. For instance VE always ends up being about 3-4 db higher in volume than with Avia, but with each individual speaker at the same calibration level. Just about every speaker manufacturer suggests calibrating with the meter pointed up, but try it both ways. I doubt there will be little if any difference at all.
