Canman, in case you have not already seen some of these reviews, here are some links to forum readers who placed their thoughts on their recent Axiom selections, several of which have compared Axiom speaker models:
the original fhw multiple model review
the dual model Randyman review
my original m60 review
m22 and qs8 review but as surrounds
sonicfox m60 review
sorry if i forgot anyone, i'm starting to lose track of the links
Hope this helps!
PS i have a large dog who is a clutz and i was also worried about getting the smaller m22s for speakers
As long as the stands are well weighted i don't think you will have a problem and as far as the m60s go, you WON'T have a problem (unless of course you have a little future linebacker on your hands)
