Sorry, I did not run any impedance measurement on them, and I returned the pair to the seller (after having tried to replace just one, but the replacement I received also had "issues").
My conclusion is that those drivers are too fragile to be bought used, the faston terminals especially: gently pushing a terminal during measurement could change distortion figures by up to 20dB...
(lower traces are 3rd distortion)
Knowing that one cannot buy replacement diaphragms...
No thanks, not for me, not even new and enclosed in a speaker...
