Help Identify if JBL 375 Diaphragm is Original?

[claymonkey]

I was very lucky this past weekend to obtain a JBL 375 driver. Since the seals were gone, I opened it up to see if the diaphragms had been changed.

Can anyone tell if these are original or new?

Or tell me how to figure it out?

Thanks!

It's real, :blah:

Is it the first one in there,who knows, does it work? If so replace the foam and forget about the seals and have fun:D

I'm not an expert on older diaphragms, but I would have thought if it is a JBL OEM frame that there should be a star pattern at the edge of the diaphragm. Obviously, this one does not have the star pattern.

Your thinking of the 376-2441 diamond edge

This is a 375-2440 smooth roll edge
