12" Duplex "The Engine" possible project

[Audio_by_Goodwill]

I may be getting a pair of 12" Duplex's. Unfortunately, they are bare drivers, no cabinet, and no horn. I can build cabinets of some sort.... probably something basic. However, I need a horn. I assume the originals were similar to the horns in my single 9864-8a that attach to the cabinet. I see GPA builds a 212 Duplex with a much smaller horn on the HF section. In their FAQ, they state they won't sell part, However.

Any ideas what I could do for a HF horn?

Use a small Mantaray 931 (1500 Hz XO) or MR 94 (1200 Hz) if you can find any or go vintage with the 811 (800 Hz).

You may want to contact this guy on eBay I think he makes horns from scratch... I don't know him I just found on eBay so do your due diligence... Maybe worth a look. Here is another set a little cheaper at $100 bucks.

I found those too. I was hoping he had one that would bolt directly. That market is probably too small.
Unfortunately I didn't get the speakers. It was a local-ish auction, and I thought I might be alone in my pursuit, but apparently several other people knew what they were looking at, too. I'll simply wait until I find whole units again.

I saw those, too. The price seemed crazy to me, but I also haven't been audio "shopping" for quite some time, so I wasn't sure.

Bill @ GPA was selling those MR931-12's for 25 bucks ea.

Of course, that might have been 10 years ago at this point.

Yes but now Great Plains no longer sells parts of any kind other than diaphragms...

I doubt if the small Mantaray or the 604 horn will fit. The Engine uses a large format driver.

Yes, But what I was suggesting is that I think he makes them from scratch maybe 3D printer. And maybe he would be able to make something for him. I figured you won't know until you ask. His store is Stein Horns.. I thought maybe worth an email.. Dunno.
