New H/F Diaphram for Urie JBL 813B

[David Ketley]

Hi Ive blown the diaphragm on the High Frequency Horn, anyone got a supplier who has one in stock? Fixing an UPS to the system to prevent any more mains spikes.
Any help appreciated very difficult to get sorted here in the UK

hey, you have to open it up and post here a picture, so guys can identify if its a 2425j or 2425h (16 or 8 ohm) , then new JBL dia is about 130 usd, aftermarket 40 usd/pc. There is also aquaplas anti resonance coated version but that has to be done by you or one of forum members. Rich indicated once that Guido has aquaplased dia's.

Readswift question is how do you gain access to the diaphragm? Thought my luck was in the lamp had blown but no it had taken the Hi frequency unit as well.
Thanks

Remove the coax driver from the enclosure. It lives on the back of the woofer.

Just trying to get some pictures up lets see if this works?

The driver is the 2425H

Check the bulbs first...;o)

Yes one bulb was blown but it didn't get me the H/F back so I presume Ive blown the diaphragm?
Can you help me to get the right one and give me a supplier.
They want to charge me $300 if they can get one here in the UK!
Thanks everyone.

Found one its 8 ohms is that correct? YES IT IS THE H designation denotes the impedance.

Just ordered one off ebay half price should be OK?

Does this unit just unbolt from the back?

Thanks
