Yes one wired out of phase with respect to the other, so that the cones both move in the same direction.
Yes you would expect cancellation in theory, but that's not what you get. I've never heard bass like it from a domestic loudspeaker.

a push/pull arrangement i'd guess
Yep
I was thinking ordinarily it would be push push in a bellows type arrangement (like some Kef Reference models) but it's complicated by the open baffle situation. Why would this not work whereas a push pull would?
There is no baffle though.
So if a cabinet were used, the arrangement would be called 'isobaric' (i.e. constant pressure between the two drivers).
Yes same idea, just without the baffle.
Completely understand, Ali.
Still trying to get my head around how these work without a fair bit of EQ, though. I imagine there is some reinforcement from the floor perhaps....but still, has me puzzled.
With a V-shaped baffle, which does reduce vibration considerably and 20db of lift my LX521s will get to 96dB @30Hz (about 26mm excursion) so nowhere near what these seem to be capable of.
