I have had this speaker in an Altec 612C Cabinet for years as a Sub Woofer. I pulled it out to mount my Altec 604-8K's in. I can't remember where I picked it up. But I think I might have gotten it when I was working Live pro sound. I figured I put it up for sale somewhere. Anyway, there is no marking of who makes it. I think it might be a Live sound Pro Electro Voice speaker. Judging by the size of the Voice coil it looks like a 5 " diameter and measures 15".!!! Also it has a Large back end opening or hole that is open to the inside of the dust cap from the rear. It is Heavy duty. It might have been used for EV's Live concert speakers which handle quite a bit of power. What's your guess????
