If you go to page 8 of the song speakers/m80's thread you see Bob has the M80's corner loaded with about 5-6 feet of separation in what looks like a very reflective room. That type of placement is a big problem which I bet is causing the majority of the issues he is having with the M80's. You put the song speakers in there and they won't sound ideal either.
