Talking with Alan and Adam about it later, we decided that it probably had to do with the fact that the M3 tweeters were higher up than the M80s.
Which is what his problem is, the M3s are higher up by a foot. I wonder if he put the M80s up on some make shift stands, phone books or criss-crossed pieces of wood, if it would help.
Now at Mojo's when we did our big comparison, we had the M3s up on top of the M80s and the M22s on top of the M60s which would put the tweeters close to that 12" mark above the floorstanders for the M3 and the M22s 16-18" above and the only speakers we found to be different from my own testing at my house were my M22s, with that thin sound we have mentioned.
