These horns came from the JBL Custom Shop. I assume they were one-offs, since they don't have any numbers on them
The motors are 2450, but the horn has an integral housing that fits over the...
Your design looks very similar to this pair I have, but with the newer horn. These were built by the JBL Custom shop and originally installed at the Experience Music Project in Seattle.
The custom...
I kept the original 4628 crossover frequency for the 2118/2404. From what I read at the time, it was best to treat the 2119 the same as a 2118.
It seems like a fairly good range. You gain the...
Anyone have any information about this 2450 horn?
The horn is thick fiberglass and mounts over the top of a 2450 with the snout removed.
It is 12 inches and is from a pair of JBL Custom Shop...
Hi,
I still listen to these, they are one of my favorites.
Here is the crossover, and a few rough plots of the response. The measurement was taken with the speakers pointing out the back of the...
No, I'm not sure where you can get this trim.
Are the surrounds cracked, on the edges. From the pictures it is hard to tell. If they are just hard and stiff, you may try loosening them up a...
Yes, this is definitely a painted LE8.
The dust cap is aluminum. You will probably have a hard time finding a good replacement, so I would try and leave it on if you can.
Do you still have the...
Those cabinets certainly have seen better days.
Do a search on-line for a program called WinISD. It is fairly easy to use and has built in parameters for the LE14A. You can quickly experiment with...
There should be a rubber "O" ring around the outside of the wire mesh, in a groove, on the top side of the tweeter.
Carefully remove the rubber ring with something sharp and pointed. It may be...
Not sure exactly what crossover you mean, but I replaced the rc1436 opamp on my 5234 crossover with the conversion unit from these guys: http://browndog-adapters.com/ It made a big difference.
This add has been up for a long time on Craigslist in Seattle:

I've contacted the seller in the past about his horns, but don't recall the...
Here is another link that has a pdf of the original crossover schematic: http://www.audioheritage.org/vbulletin/showthread.php?24116-Altec-Crossovers
Hi Michael,
Welcome!
Do you have any pictures of your crossovers? I did a quick search and it looks like the AS101 may be a clone of the Altec Valencia, with an N-809 8A crossover.
If so, it has...
I have a Mac-Mini with several 1st gen Apple TVs (the ones with internal hard drives) in the shop and around the house. The Apple TVs sync up automatically with the main server and I can listen to...
Yes, one connection from the minus side of your power supply to ground.
You need a separate resistor at each point, otherwise you will be linking all of your caps together at the junction. Signal will flow where you don't want it.
You might try visiting the plumbing dept of your local box store to see if your threads match a standard pipe size. They may have a flange or something that could be re-purposed easier than starting...
I had my daughters do some artwork and printed up a few samples.
The gold color did not work, the ink is translucent and the gold didn't show up on the wood at all. I think there are other printers...
It is just an 8.5 x 11 sheet, you need trim around the area you want to apply.
I bought a few sheets of print-it-yourself water slide decal paper to recreate some lettering on a tube amp. Like this:

It worked great.
I have extra,...
I don't have these around any longer to take a picture of.
The grills were pretty simple, though. Just a simple frame, the minumum depth needed to clear the thickness of the woofers.
It's a healthy addiction :)
Thanks,
The veneer is 10 mil paper back, cherry and was applied using contact cement.
After removing the finish and sanding, the previous veneer made a good base for the second layer.
So, I ordered some rift sawn cherry veneer from Oakwood veneer and set about re-veneering the boxes.
To prep the boxes, I cut a thin groove about 1/16 by 1/16 onthe front to act as a transition...
