separating the M60s about 12 feet

That's pretty close to the separation I had in mind. Something like 10' or so just by eyeball. I'll know more when I have them set-up and running and get the sound of them in my ears.

have you considered moving?

Hey! I just moved in here last summer! And when we saw this room, we immediately thought "Home Theater". It's just an evolving process to make that into a reality.

G'Night!
