Elberoth2,
Interesting to hear that the tweeter settled. I'm pretty sure the pair I demoed had more than 400 hours as the dealer has had them for a few months. The dealer has ordered some resisters to try attenuating the low frequencies. I'll ask about the high frequencies as well.
My room is treated, but more relevant to my issue, it is soundproofed. Between a concrete floor and soundproofed walls/ceiling, the bass doesn't have anywhere to go. I have some RealTrap traps in some of the corners (not all corners mind you).
The difference in low frequency extension between the Sophia and the Sasha is huge though.
I've just ordered RealTraps latest product - 'MegaTrap'

I ordered 10 of these, and it's going to take some re-working of my room to get these into the corners. If that doesn't do the trick, probably nothing will, well apart from the resistors perhaps.
Elberoth2, what is the performance of your room like with regard to bass leakage etc?
