Kracken, you certainly can fit the M60s in that room. As i mentioned, mine is very similar in size. However be prepared to tweak and tweak and tweak.
You may fuss to no end.
I recently brought my Axioms over to a friend's place last week over New Year's. The difference in placement and room acoustics in his basement compared to mine was stunning. He had a slightly larger room and obviously some different interior design.
The next time we select a room for the M60s, it is my preference to have one larger and with a better build than a horrible drop ceiling.
