The fascination of vintage hi-fi: A Look Back

Thank you for the nice comments my friends. I posted it on here in Virtual Systems. It's listed as doyle3433's horn system or something like that. I posted it Nov 3, 2021. A couple before shots and then finished shot of it in the house. it has a an altec crossover that i don't think is in the pics. I have it hooked up to a little 30w integrated. 

I'll never forget cleaning it up and ran a garden hose down the horn throat, the crud that came spilling out.. yuck.. (of course driver was removed, which feels like it weighs 60lbs)

Wow, that thing is a beast. Thanks for posting the images. I know zero about the manufacturer. Did you research it at some point?

I am a big fan of 1930-60 horn-compression midrange systems.  IPC compression drivers can be VERY good.  I particularly like Western Electric drivers and horns and some later Japanese copies, and designs inspired by, Western Electric. 
 

In my own system I run Western Electric 713b drivers and 12025 horns.  I have modern woofers, but they are old-school—twin 12” paper cone drivers with pleated surrounds and alnico magnets in an Onken cabinet.  The tweeters are modern (Fostex bullet tweeter).

There’s not much information I’ve been able to dig up. It seems the drivers themselves were made by Jensen, for sure the woofer was. I’ve been able to locate a few industry catalogs. They mostly show projectors etc.. but do show the drivers also. When I refinished the cab I left the stencil marking in the back, International Projector Co. NY. 
when I wrestled the horn and cab out of the theater it was mounted in a very substantial 2/4 and plywood mini wall behind the screen. I was covered head to toe in sweat and soot. 
it seems to me that per the catalog, the installation crew were left to their own creativity.

I’m now on the look out for more. My wive is thrilled.
 

Interesting, @doyle3433. In my very perfunctory research the name of the company came up on the Altec Heritage site indicating that Altec made woofers for some of these- but perhaps not the only supplier. 

What a great find! Enjoy it.
