Hey David... and welcome!
I have that same exact setup... the 60's, 150 and EP350 ALSO in a 13' square room and I absolutely love it. I was prepared to spend many thousands more for my "dream" speakers; thank God I stumbled across the Axiom name and got my dream speakers for an awful lot less!

Hurry up and order them, leave your receiver on "8 Ohms" and post pics afterwards!
