According to Rythmik, "With HX800XLR3 amplifier, one can drive two drivers with one single amp. It has two Hypex 400WRMS power amplifier modules in one heat sink so that each module independently drives one driver with servo control."

This would seem to circumvent the "no 8-ohm Al-cone 12" issue.

(PS--Sorry for lack of links... as a newbie, board software won't yet allow me to include 'em.)
Excellent! I had forgotten about that new Rythmik amp, made for exactly your desire of a dual woofer per enclosure sub. That will make a great sub!

I'm leaning towards putting two 12-inch Rythmik drivers in my old Velodyne ULD-15 enclosure, in a sealed push-push configuration.

Given that the ~ 2.5 cubic foot enclosure is about the right volume for a single 12-inch driver, I reckon that it is also about right (to first approximation) for 2 drivers in a push-push configuration. Each driver would "see" an enclosed volume of ~ 2.5 cubic feet, more-or-less independent of the other driver.

In other words, the Velo box should work as well with two 12-inch drivers, as with one.

Am I correct in this line of thinking?

As long as the 2.5 volume is the required volume for the Rythmik, any 2.5 cubic foot enclosure would work...

The Rythmik aluminum-cone woofer is spec'd as needing a 2.0 cu.ft. box, so the OP will have a half a cu.ft. for added bracing, a very good idea. As for two woofers needing the same volume as one, that I don't know. But two opposing drivers can't be a bad thing (as Mark Seaton will tell you. Bill Fitzmaurice, on the other hand, disputes the claim of force-cancellation resulting from the dual-opposed woofer design).
