I have an old pair of 2405 slots that I just bought and that have been used in pro SR.

Are there plenty of JBL OEM diaphragms for these drivers or are they now getting more scarce?

I assume JBL will no longer make these as a result of their decision to no longer cater to the vintage community; right?

My drivers have OEM frams and they work, but I assume they have been hammered a ton.
