New Western Electric Project

To the baffle size comments above, I think I would extend the baffle to the ceiling, once I decided where I wanted it. With the lower ceiling of a basement, it's certainly fairly easy. You could simply cut a hole big enough for the 26a to pass through. This would likely lower that response a good bit.

It would also give you a spot to hang cool rock posters..... :D
 
I still need to build the side and upper baffle extensions so complete the setup. The soun is good but there is some distortion in the lower end of the mid driver. I traced it to the crossover I was using. The crossover was from a total different build and was not optimized for the drivers even though it had the right crossover points. I'm in the process of winding my own inductors for the new crossover which is a 12db Butterworth just like WE speced for the system.

I used the available drawings of the 7396 that are on the internet. If you scale the pictures you will get all the info you need to build them. If you overlay a WE blueprint drawing over a picture of there products they match perfectly. I also used many saved pictures of the baffle that I found on the web for reference.
 
Some more updates. I built a new crossover. Its a 2nd order Butterworth. The original WE is a 2nd order Butterworth. I wound my own 4.5mh air core chokes using 18ga magnet wire and used PIO PCB oil caps. 35uf in total (10,10,15uf). Crossover is 400hz.

A fellow Forum Member has helped me with a new throat. The 22a adapters I have are for WE 594a's and the bolt pattern is smaller. So I wasn't able to use a modern 2" driver. But now I can use modern 2" drivers tanks to Tsingtao_1903.

I've been planning on winding my own coils for my horn system as well, but haven't figured out a good way to count the turns as I go. Short of buying one of those manual turning machines with counter built in.

Mind if I ask how you did it?

Excellent progress, how's it sounding so far?
 
I used one of those cheap Chinese manual winders on eBay and a air core calculator on that diyaudiovideo site for the exact amount of turns. Which that calculator was off a few turns. I created the bobbin out of 1/2"ply and a 1-3/8" wood dowel from Lowes.

The sound has gotten a lot better with this New Crossover as the old crossover was something I had laying around that kinda of fit. I still need to install a attenuator transformer for the mids and a L-pad for the tweeter.

That was my basic plan as well, now to stock up on magnet wire!

The Atlas Sound AT-100* in wall attenuators work surprisingly well, not nearly as refined as my mast_mutter autoformer, but great for prototyping and using until one saves the cash for an autoformer, or one of Dave's speakerformers. They can be had on ebay nice and cheap too!
