Default What Would YOU Do With This Cabinet?

Howdy, first post. I've been learning a lot just reading.

I got this cabinet on Craigslist for 50 bucks. The seller found it abandoned in a warehouse 30 years ago, and had always meant to do something with it but...

I'm putting together a tube based mono system. The amp right now is a Heathkit A7 putting out 7 watts. Source will be the music server. I've got ideas for this cab, but you guys have the experience. What would you do with this thing? And although I'm posting in Multi-Way, I'm open to Fullrange solutions too, but I don't have the bucks to compete with our Korean friends for a Stephens True-Sonic.

This looks to be a home-made cab, but it's really well constructed. 36" W, 32" H, 20" deep.

The baffle is for a 15" driver.

The seller said it's a dual folded horn. Is that correct?

Thanks for any suggestions, and have a happy 4th of July!

Almost certainly designed to use a structural corner as an extension of the internal horn path, ie, should be placed in a solid room corner

Flaesh's link isn't English but gives some nice pics of how to brace it. If it were me I'd throw a PA driver in there along with a small plate amp and build two satellites to complement it running from your Heathkit. Voila, instant system with enough gusto to impress your friends.

Fascinating! Thank you all! And thanks to Flaesch, I know it's a Jensen cabinet design, and I found the original plans, should I ever decide to expand this into a stereo system:

Funny thing is that I understood the Russian link more than I did the Econowave one--I don't speak at that high of a technical level, I'm just a piano player...

Lots of possibilities. A vintage co-axial, and it's an instant two or three way. Or, some good used JBL components with a separate horn and driver on top. I like the looks of that monster one on the Russian site.

And yes, it can be used in a corner to good effect, but the original Jensen doc says it isn't necessary.

Keep the ideas coming, I'm psyched that I scored this thing. But damn, it isn't my idea of compact, it's three feet across!

I nabbed a JBL 2220A 15" last night for a good price on eBay. So instead of the vintage coaxial route, I'll be adding a horn and crossover to this guy. I'm anxious to hear it just with the woofer. It doesn't have the cross braces like the original plans show, or the photos in Flaesh's link, but I can add those if I get some wonky vibrations or resonances. Those shelves aren't for structural support, this thing is solid as a rock.
