You don't want to be running the M80's set to large at reference levels EVER with these highly dynamic blu-ray disks which most are mixed "hot" in the midbass and bass department. You do not want to try to repeat this issue because you can be at risk doing permanent damage to the speaker.
your correct, i didn't realize that he didn't have a sub when running them, i thought it said 3.1 so i was surprised at the settings. most receivers will set the fronts to full if no sub is there and your correct, it's not a good idea when trying to run blu's at such an incredibly high volume level. i was in the middle of editing my post when i saw that and tried to simply delete it and start over but it wouldn't let me delete it.
