KEF 107.2 with KUBE?

I've read that the design of the KUBEs is specific to models of speakers. The installation instructions for the KEF 107.2 warns that a 107.2 KUBE should be used with 107.2 speakers, but does not mention that KUBEs are adjusted for individual speakers. If that were true, a KUBE would need to be readjusted any time a driver is replaced, reconed, or received new surrounds. The 107.2s I'm buying are said to have had the cones and surrounds replaced recently -- before the seller became enamored with ultra-low wattage amps that require even more efficient speakers.

J24,

Recalibrating KUBEs when a driver is altered would be necessary only if KUBEs were calibrated for individual speakers, something neither of us thinks is likely.

I reread Olsher's review of the 107 in Stereophile. I think I discounted that aspect of it because I suspect hyperbole. Is it logical that contemporaneously built speakers would have such variations, yet the factory could build a given speaker with such precision to match exactly a previously built speaker? If that were so, why then would there be the supposed variation? And lest we forget, those KUBEs have HF and LF gain controls aimed at tailoring the sound to particular placements and room acoustics.

But if I read the review literally, I should be able to send KEF the serial numbers of my 107.2s and get a KUBE made for them. Unfortunately. my 107.2s, like so many others, were reconed with new surrounds in the US. Woe is me!

I understand there were some 107/2 KUBEs with balance XLR connections.  I'd pay $1K for one of those.
