Hello all,

I am new on this forum. I am found of JBL audio system since 25 years!

My system is an active 3 ways with 18" 2268H in vented box, a CMCD-81H 8" for the midrange (350 - 2kHz crossover points), and a 1.5" 2452H for the upper range.
At first, the HF driver was a 2431H Neodynium, but its frequency response was not good above 10kHz. And despite an efficient EQ with the the DP226 FAN, it doesn't sound very good.
So I replace it by a 2452H and it was a lot better.

By now; I would like to improve my 2431H, and I think about the Beryllium diaphragm of the 2435H. I would like to be sure both diaphragms are compatible (2431 vs 2435), and that a 2431 with a 2435 diaphragm is really equivalent to a 2435.

Many thanks in advance,

Regards

Bruno
