As happy as I am with the VP180, I would still like to try a WT/MW unit from Axiom one day. I don't actually expect it to be better than the VP180 in terms of sonically matching the M80, but it would be nice to see if the horizontal off axis performance is significantly better, and to see how much (if any) of the vertical off axis performance is affected by the vertical T/M alignment.

If a single small mid driver (required to keep cabinet size down) is a concern then perhaps they could try a WMT/MMW layout that uses a small mid driver under the tweeter, flanked by larger mid drivers and then woofers on the outside.
