Please read the first article I posted again. On page 3 it is written.I must come back around and mention that I now realize Milab/Pearl is simply using aluminum on Mylar… I knew that! What was I thinking? Doh!
I also realize I already knew how thick the NU-100K aluminum is. Martin had already confirmed with me that it’s a 6-micron pure aluminum diaphragm in a 30mm capsule.
Anyhow, I truly would like to find out for sure how thick the aluminum on the kk53 was. I truly would love to be absolutely wrong!
