Ok fellas, I'm back to report I got both my 2245H reconed and my 2420H horns repaired with new Radian Diaphragms by Ken @ Upland. Ken did a great job on both and now I can get back to my JBL 4345...

I have all the test equipment to do it but I will talk with Ken about these when I pick up my 2245Hs he is doing.

I will talk with Ken when I pick up my 2245H that he is doing.

thanks

Seems like I will just need some masking tape to clean out the gap where the voice coil goes in and a Oscillator for a curtain frequency to make sure there is no buzzing? correct? If there is buzzing...

Wow, I didn't know that! Thank You for the info! Glad I asked here!

I did find an older thread about felt for the back cap, there was a link to McMaster-Carr for that item. I ordered it just a few...

I'm planning on replacing the diaphragms in my JBL 2420s this weekend and wanted to know what is the proper procedure for doing this. I have never done this before on a CD and don't want to make a...

Here are my Kenrick Lenses.

Today my JBL 2405H super tweeters came in. They do show some signs of wear and are missing the JBL model decals but are in good condition.

Thank You for the info on the foam. I just need to find some new foam and then remove the old foam. Just one more thing to do but I was already ready for this. LOL!

Yes, I had already purchased the Radian 1225-16's a while back when I had purchased the 2420's just incase. Glad I did.

really? I thought the diamond shaped suuround of the diaphrams was the original one and the broken was after market. If you look closely the foam that was covering the damaged diaphram says it all....

Today I opened up the 2420 CD's to check them out. I found that they had different driaphrams as you will see in the pics, but that wasn't all I found. The one diaphram that looks after market was...

Thanks, for the help and info. I wasn't really stressing, just wanted to make sure I didn't have to do anything else if the driver impedance wasn't correct. So now I think I have a better...

Ok, so lets see if I got it.

2420 with 8 Ohm diaphrams (measure 6.0-7 Ohms) remove the 20 Ohm resistor from the network?
2420 with 16 Ohm Diaphrams (measure 12 Ohms) leave the 20 Ohm resistor in?...

Hello, I had this info on my laptop but it died on me a year ago. I can't locate any info for the original JBL 4345 raw driver impedances. I just want to make sure that the 2420 and 2405 are what...

Here are some pics of mine JBL 2420 with 2307 horns. They are in really good condition except for the circle type scratches on one of them. If it wasn't for those scratches these would have been in...

No Problema! :)

I went there but nothing. I did find an old thread that had some that looked like the originals over on the EHC website.

I need to call them tomorrow and...

Today I bought some speaker mounting kits for the 2245H's. So now I just need to find a source for the knobs for the L-pads. The one's I'm finding are expensive, the cheapest are $69 for 4.

Ian, Thank You. I placed the order today for the 2405H's. once I receive these, I will have all the JBL drivers to start the build. I also picked up some foilcals for the my project. I just need the...

I went to the website but it looks like its no longer a working website. I will call the number tomorrow that came up in a search.

Hello all, here's and update to what I have done. I know it's been a while but I was laid off again and had to wait for awhile to get the funds for these drivers, horns and lenses. Today I was able...

Why is that? due to the color?

Here are the 2245H's I was talking about that need repair. The one that is showing the back seem ok. The other has a crushed dust cap and is rubbing when you gently push down on it, so this is the...

dino, Thank You for the advice/info. I will look it up.
