Arthur, room correction in the bass frequencies is a primary Audyssey(the MultEQ versions, not 2EQ)objective, so yes, it should "help", but to what extent is uncertain until it's tried. It's a bit unusual that a new room would be giving you so much trouble. Can you describe the difference in dimensions or any other difference that you think might be relevant? If possible we'd like to make some suggestions short of buying new equipment. For example, although it's a relatively crude adjustment, have you tried turning the bass tone control on your 3480 down a bit?
