Thanks for the help guys, I've got them dialed in perfect now and they sound even better than my initial review. I just moved the whole system over and forward about a foot. That allowed the 80's some more side and rear clearence, and balance everything better in relation to my listening position. The 80's do seem to need a little more space (side and rear) than the 60's did for optimum sound.

A computer once beat me at chess, but it was no match for me at kick boxing.
