Hi all,
I recently purchased a pair of Fostex T825 super tweeters, probably about 40 years old (originally from Fostex Laboratory series LS/3 monitors).
After a quick sweep the measurements lead me to believe one is faulty.
Does the lower trace show signs of a bad diaphragm? Or diaphragm not aligned/seated properly?
One sweep is with 4.7uF cap and another with 1.0uF cap.
Both measure 6.7ohms
Thankfully, the seller is willing to refund if I'm not satisfied.
Looking for some opinions before I bring them back.
Serial numbers are almost consecutive (11156, 11158).
