Oh yes, I have Visaton FRS5X somewhere and also a pair of 2" Sica fullrangers. Might be worth trying out with a 3D printed adapter.
I printed a some flanges, two more are printing. The drivers under test will be:
Visaton FRS 5 X
Sica 2 H 0,8 SL
ScanSpeak R2604/833000
Selenium D250-X
TEBM35C BMR speaker
All reduced by a short conical section to 36 mm (the 1" driver is of course expanding).
