Jarek, those are good photos, but I still can't be sure. Are you sure the surrounds are paper, or might they be [partly] thin cloth? Whatever, there's a good chance that any solvent that will soften the dope that's on the surrounds will also soften adhesive that bonds the cone to the surround, or, if there are two pieces involved in the surround, those are likely glued together, also. It is typical of all speaker mfgs that they change things like surrounds almost willy-nilly, without so much as changing part numbers, and, as you likely know, there are several iterations of Tannoy Reds floating around, not to mention plenty that have been repaired. Perhaps there's something worth seeing from the back side? In any case, start small, and take it easy. Do a little work and let it dry, let any softened glue re-set (if it will...) before starting up again. If any glued-up parts come apart, I recommend you glue them back before continuing, unless you have a good plan for keeping or restoring the cone/voice coil where it is, relative to the gap. Obviously, if any part of the surround is foam, solvent may well melt it, and you probably can't scrape it without destroying it. I have seen plenty of the black dope used for repairing cracked and/or torn surrounds, which are revealed if/as the dope is scraped off.
Best regards,
Paul S
