Diaphragm for 375 driver

[Dr.db]

Is it correct, that the original JBL replacement diaphragm for the 375 driver is the D16R2440 ?

Did JBL use the D16R2440 diaphragms from factory in the 375? Or is this just the only currently available substitute?


Thanks a lot,
Olaf

It must have been called something else in the 1950s and '60s before the Professional Series and the model designation 2440, but it is and was the original part that was always used in the 375. That is the correct part to maintain the performance of the 375.
