Well, to compare them to the Polk R50's that I have on loan :-) from Circuit City, the M60's are a little less efficient(about 3dB difference), but more clear and smooth. The R50's seem to emphasize any echo in a song, and also put Blues Traveler in a box. In general the M60's get the sound out of and away from the speakers, where the R50's sound more boxy. (And unlike Volvo, boxy here is not good.) The M60's have cleaner slightly deeper bass than the R50's, and it's more balanced. In a sweep test the R50's hurt my ears, where the M60's don't. The M60's also have better - wider, higher and deeper imaging. (My better half also says that the R50's sharpen the upper range in pitch from what it should be. She also says that vocals (both male and female) sound much more natural on the M60's.)
Oh, and the Boston Cherry finish looks much nicer than the Polk black, even if it is real wood veneer on the Polks.
The R50's normal price is about $560(I got them on sale for $400), while the M60's are $800(I paid $680 for them from the FO). So, I would hope for $280 more they would be better. :-)
(When reading this please don't confuse the Polk R50's I am talking about with the Axiom M50's that I have never heard. :-)
Some more bad news, while the outer and inner boxes of the VP150 where OK, one of the woofers has a defect. Really weird.. Here are a couple links to pictures of it:

I'm hoping that Axiom can send me a new one of it with the other parts, but they haven't had a chance to respond to me yet as they are closed.
