Hi Alan,

My room dimension is approx. 13 X 20. There is a vaulted ceiling, but I don't know the exact height (possibly 15ft. at it's highest point). I was also incorrect about saying that one of the walls was *entirely* open. The wall I'm talking about runs the length and has about 6ft of wall with the remainder 12ft open. The width perpendicular to this side is where the TV is and the main speakers are(which are about 15 inches from the wall, but again are only about 5 1/2 ft. apart). The listening position is about 13ft. away.

By reading the encouraging comments by chesseroo (thank you for your thorough response, BTW!), I'm really hoping that the M60's will blend nicely being so close together.
In case it matters, I've got the Denon 3802 receiver and my current Infinity's are like the Axiom M40's (one woofer, one tweeter)design. The Infinity's are working well in this position.

Thanks again. I appreciate all your help!
Mary
