I have a vintage, what appears to be Eminence 12" speaker that came in my Ampeg Gemini I. It's not the original speaker. It rattled like crazy when you approached the low "A" note on any guitar. It had an aluminum dust cap like a JBL, silver (raw) frame with 4 holes and a small horseshoe magnet that I assume to be alnico. 8 ohm... It had a stick on the magnet that said "Sunn Guitar Transducer", but when I pulled it off I saw the 87xxxx stamped into the magnet. Either way, it was rattling around in the back of my van and the dog decided stand on it during the ride. She pretty much ripped the cone right out of it. I assumed it was a goner anyway, so no loss... But does anyone have experience with them? Is it worth reconing? I have a shop nearby that recones. It looks just like the ones in the attached pic.
