Hello Alan
Well, you've been sworn to secrecy, but permit some speculation based on the following observations:
1. The largest driver which any of the current center speaker cabinets accommodate is 5.25";
2. The Merak MC6H cabinet (also anti-standing wave trapezoid) can accommodate 2 x 6.5" drivers and a great big honking 7" x 3" horn driver.
3. A center channel speaker with 6.5" drivers may be a better match for the M60 and M80 towers.
Speculation:
1. Axiom will use the Merak cabinet for a center channel speaker with 2 x upgraded 6.5" drivers, a 7"x3" horn tweeter;
2. Axiom will make a new cabinet for center channel speaker with 2 x 6.5" drivers, a 7"x3" horn tweeter AND 2 outboard Titanium tweeters. (I'd consider one of these!)
Just guessing.
