Thanks for clarifying/confirming, Dave.
As it is possible to upgrade the S2EX to the Diamond Tweeter, assuming that it would also be possible with the RAAL Towers, albeit at a substantial cost considering the Tweeter cost - correct?

I recall that the standard done tweeter can’t just have the Raal ribbon tweeter swapped in, unless you have some woodworking skills. If the diamond tweeter is the same for the bookshelf and tower, I don’t think it would fit the tower, if it is replacing the Raal ribbon tweeter.

Diamond tweeter will fit in the Sierra-2EX and in the Tower, regardless if the tower originally had the dome or the RAAL. However, the crossover will need to be changed to properly accommodate the diamond tweeter (for any of our speakers). Changing the crossover in the tower is complicated.
I actually don't recall if we made any additional changes from the original prototype pair of EX woofers to what we ended up with. We had several rounds of samples.
It is certainly possible though, perhaps a change to the DCR of the voice coil (DC Resistance). I don't think we did, but at this point it is hard to remember.
Yes, it can be done with our towers but for this I recommend letting us handle it. The diamond dome is extremely fragile, and while it is protected by its own grille, a misplaced screw could spell disaster and changing the crossover in the tower is difficult and requires soldering.
thanks, Dave. I'm quite happy with the RAALs in the Tower so will likely not do this upgrade, at least anytime soon, since I recently placed an order for a Horizon with RAAL, considering the 2EX upgrade for my S2 and in the processing of buying some land in Brazil (wife's home country).
Would the RAAL 70-20 used in the towers fit the Sierra 2EX? I know the 70-20 has some advantages over the smaller 64-10 variant, like being able to have a lower crossover and lower distortion…if there’s a desire for an “end game” bookshelf that would be more accessible to the masses, maybe that’s a modification that can be made?
