Yes, they had numbers. They're so rare that it may not help a lot to know them. Here's some data.

A bite of reality. I was walking through the house ten days ago or so, trying to decide what to take out of the house and stow in the RV, in case we needed to evacuate and leave the house to the...
This is an older thread, and I'm not sure that the tech support is still needed. So OK to go way off topic?
The younger generations have a new saying, "OK Boomer"
It has a double meaning for me,...
The little JBLs are fun, as for the L15s in particular, I thought they were the best in their class at the time. Times do change. Give a listen to these LSR705Is if you get a chance. The low level...
I think that Rogers sound labs built a company based on the idea of making speakers that sort of look like JBLs.
I've been greatly enjoying listening to the Blind Barbers.

I would assume so as well.
I think I saw the rig for sale once. Some metal plates cut to match the profile needed from the side, and a bow with a hot wire for cutting.
There is a small response anomaly caused by the diffraction or reflection from sound traveling across the front of the baffle and meeting the edge. The frequency of this anomaly depends on the...
I went to Polaris electronics training in the Navy, (Dam Neck VA) but there were no L15s there. I did visit with a guy once back then who had L15s sitting on the floor. I thought that they were too...
It looks like you already have air core inductors.
These midranges tend to fail where the voice coil wire attaches to the terminal post. Flexing breaks the wire. I have also seen a couple that were bad due to the solder mixing with the glue at the...
I haven't listened to either but I found this JBL tech note to be a good read.

I think I'd start by looking up the original fan by its maker and part number.
Then start looking in fan spec tables for something similar but quieter. Try this:

We can trust that it doesn't matter.
I've always wanted to drive west on Sunset to the sea. For some reason. Gonna have a rental car this time?

I think I see the old aluminum dust cap still there. Or at least the outer edge of it. The way some people remove the dust cap is to cut the center out. It avoids tearing the paper of the cone. So...
I think that your foam is much thinner than it was when new. It's supposed to press up against the back of the dome and conform to it's shape. it should feel springy, not gooey.
When the genuine parts are so reasonable, why bother with aftermarket?

You may be able to see the back of the woofer through the port hole. If so, you can push it forward from there.
You need to be able to add the crossover between the pre-amp and power amp. An integrated may not work as you need the pre-output and power amp input jacks, and they aren't always provided. Sometimes...
2450 is 2 inch throat, larger then the M2 horn with it's 1.5 inch inlet.
I really like the finishing details on these. They remind me of high end Tannoys.
Did you see this older thread?

I'd try to find something nicer than pine. And thicker.
