I have to agree with Ray3 here. Of all the not-top-of-the-line Axiom speaker owners on this board, the people who own the M60s are somehow immune from ungrade-itis. This is a very important fact as it indicates complete satisfaction.

Unless your room is cavernous, you won't be missing anything by purchasing M60s. They're cheaper, they're easier to position, they don't require as much current, and they sound damn near identical to M80s. If you do like strong low bass, even an M80 owner would recommend augmenting your system with a quality subwoofer.
