Does anybody have a schematic for the 4425 Network?
I think its the 65934-00.
Thanks

Thanks Giskard!
You are the fastest
But are you shure? I meant the 4425 with the 2416 Driver and th 2342 Horn.
Damned!
Youre right. As always and I was blind
Thanks!
Now some details:
L1 seems to be a inductance (coil) with fixed resistance. Where can I get this?
What is the resistance of the L-Pads? R201 and 202
Thanks for help!
"L1 seems to be a inductance (coil) with fixed resistance. Where can I get this?"
I don't think JBL has any of these anymore. They are little 1.0mH air core inductors wound on plastic square bobbins and they have a DCR of 7.5 ohms. You should be able to get them custom wound or wind them yourself.
"What is the resistance of the L-Pads? R201 and 202"
I'm not sure. Call Dave at Pro Parts? Or send their support an email. They need to post a readable tech sheet for that system anyway...

I am pretty sure they are 8 ohms Attached is a clean copy of the techsheet with the part numbers for the pots.
I downloaded this unreadable techsheet to
But thanks to Rob I now have a readable
I bought one of these coils of the same value 1.0 and 7.5 dcr from jbl pro just two weeks ago for a L46 that I am building. It cost $13.00. If you need the part number I can look it up on Friday when I get home.

Cool!
I've posted this inductor several times before in previous forums, I don't see it anywhere on this particular version of the forum so here it is again:
57129 - 1.0 mH 7.5 ohm - $11.31 from Pro Parts
Here's the other important coil that I've posted at least a dozen times, alas, all on previous versions of the forum:
56138 - 3.5 mH 7.5 ohm - $15.63 from Pro Parts
Ok, call me stupid but:
Why can’t I take one 1 mH coil in series with a 7,5 Ohm resistor?
How about a 1.0 mH coil having a 0.5 ohm DCR in series with a 7.0 ohm resistor?

Here, this will work -

Again Thanks!
Now I can start to rebuild.
Here is an link to an excellent site for X-over and speaker components.
It's switchable to english and the ship overseas.

Ok, call me stupid but:
I don't see where to switch it to English
I don't think you're stupid - I don't see it either, and gave-up, just shy of Registering!
