Hello,

I have a pair of JBL 2440's with JBL 2395 horns as part as an actively crossed over system (800-8000Hz 18db/oct).

I have noticed a distinct decrease in HF output from one driver recently.

I tried swapping over the amp outputs, the speaker cables and also the protection capacitors (22uf bi-polar electrolytics)

But the HF decrease remains only on one side - so I have narrowed it down to the compression driver/diaphragm - but which is it!?


the driver is not going to suddenly demagnetise itself is it?! It would have to be dropped for this right?

So I have ordered two JBL Diaphragm D16R2441 - for 2441, 2441J to try fix the problem

anyone got any suggestions at all?!

Thanks
Tom
