No typo. I'll try to move them out a little.

As for the room, I used a tape this time and got:

13' from speaker front to ears
8.6' between speakers

The room itself is 16' x 22' *BUT* has 22' ceilings, 25' of open catwalks over it, and 16' of door openings on the ground floor. I figure it to be ~7000 cubic feet. Does this make more sense as to the choice of the M80s? Thanks a ton guys!
