Thanks Prof, really appreciated. I checked with Rob today and he has sold a lot of his inventory and all his 3.7 were reserved. He could not account for my measurements but indicated that he could rebuild all the drivers, XO and they would be good to go for about 1K each.
I have not heard any evidence of any drivers malfunctioning so I'll first double check my measurements and let him to do troubleshooting.
Unsound, did you notice a notable difference after the rebuilding?
Well, will take it one step at the time.
