ok, I've been playing around with my setup. (FYI mounted the speakers just over 6ft up on the wall. I was having some receiver issues and not getting any sound to come out of the speakers (or hardly any at all). Had to do a complete reset, then manually had to bump the surrounds up +10db (fronts are at 0db, center -1.5db). Also set the sub to +10db. Does this make sense that I needed to bump the surrounds up by so much. They do sound good right now. (Going to have to take up WhatFurrer on his offer to come over with his SPL meter and Avia disk.)
