I think there is one in Michigan somewhere, and one in Oregon. The one in Oregon that I am thinking of does a lot of car radio speakers too, which are oval shaped, and they were reasonably priced compared to some of the others. When you look at what the cones and spiders actually cost, if you can find them, it makes many of the rates charged by some shops look like a ripoff. But you really have to go by reputation, some shops won't even touch a vintage speaker, claiming that can't get parts, which is partially true, but the real reason is that they would rather recone someone's JBLs for $150-175 a pop with off the shelf parts at a tremendous markup. I say partially true since a generic cone can be made to fit an old basket with minimal effort, it's only the voice coil and spider that could be a problem and require them to make something, which many either don't know how or don't care to do.
I myself would recone speakers if I could find the parts, I think that the 116X uses a 10'' so at least you can find those easily enough, mind you all bets are off if the voice coil is wrecked. At least these use a center mounted spider of the 45 RPM adapter style, you can make those yourself if you can't salvage the original.
