The general consensus of those on the board who have heard the B&W 600 series is that the Axiom M60s are noticeably better -- not to mention cheaper. It's also been said that you need to move up to the B&W 700 series to start getting on par with Axiom performance.

With the M60s, you get the tight controlled bass, crystal clear highs, and smooth accurate midrange without a boxy effect.

If you're looking for big slam, you'd do well to consider adding a subwoofer if you don't already have one.
