Thanks for response, and tip on calling Crutchfield (who weren't that helpful/knowledgable).

I've contacted Brent @ Axiom, and the good folks at Axiom don't have any miracle ideas either, and directed me to Omnimount and Racksandstands. I asked about this Sanus wall mount but they're recommending against given the height/weight of the M22ti.

So... once again asking if anyone's gone with any other mounts that don't require speaker drilling? Anyone have a particularly good shelf solution or design?

Thanks,
Rich
