Axiom is very responsive to special orders. I think it is one of the things that really sets them apart.

I have M60's and have heard M80's on several occasions.

To my ear, the M80's are "better" and the only reasons not to get them would be price and form factor. They are a couple inches deeper, and while that may not sound like much, some board members over the years have had trouble positioning them.

OTOH, you could also seriously consider getting M22's and a good subwoofer. This solution would provide you with the placement flexibility and imaging you're looking for without all the cabinetry.

Good luck and have fun.
