My room is 12.5' x 25', but I'm sitting about 8 or 9 feet away from the M22s. I was listening to Jamie Cullum's Twentysomething while I was poking around the house and waiting for little monsters to show up at my door. The sound was full, rich, loud and not strained in the least. Pair them with a nice sub and you shouldn't be disappointed at all. But if you can make yourself budget and wait a little longer, it sounds like you're a good candidate for the 60's.
