Yamaha HF-Driver by JBL

[reellamer]

Hello!

Because this is my first thread I first want to thank you for this great forum!:applaud:

First of all please be patient if I make some mistakes in grammar and so on, i'm not a native speaker!

So lets start.
Some time ago I was able to get some really big mid-high horns labeled as yamaha H6115. In 4 of the 8 cabinets there are mounted some compression-drivers. All diaphragms are destroyed, either voice coil or surrounding (beard?).

Because they look like JBL 2482 I'v bought a pair of new diaphragms but the originals are much smaller. So I have 2x Radian 1282 and no driver. (If you can sell me a pair of drivers with destroyed dia fitting with Radian 1282 please feel free to offer it to me ;))

So I'm searching for some diaphragms which fits in my Yamaha JA6601 driver, hope you can help!

I hope you can help me, I'm looking forward for some answers!

Might have a look at diaphragms for JA-6603 (phenolic?)
and JA-6681, which is purportedly similar. Possibly check with
Meyer Sound...

I was in contact with yamaha customer service some time ago and they said there are no spare parts for ja6601 driver or h6115 cabinet available.

The driver above the woofer is a JA6603 - it seems to be a completely different one compared to my 6601. But I can mistake also:

But the 6681 looks like mine, when i see the plot I could cry - 8 horns, 4 drivers, no diaphragms :banghead:
