Thanks Paula A, I have looked into re centering, the main problem is getting the dust cap off, the speaker is only an 8" but it's 70 years old, the cone is very "dry" the cap is cloth/felt, I will try and cut the cap out, leaving a rim just befor the glue line, then it's out with the fag papers, then glue the diaphram back down, once done i can cut a new slightly larger diameter cap out of some suitable material and glue that on.
i did a smaller speaker last week that was rubbing, it was very fragile so I broke all the rules and un did the screws holding the pole piece asembly, withdrew the pole piece and took a few microns off it with some fine emery... It works fine now.
I will sort it all out one way or another.
