Tannoy should hopefully be able to supply these diaphragms, but it has been 5 years since the pepperpot SE line was discontinued, and GR diaphragms are not compatible. I have a couple of these in a drawer somewhere. But this is probably not your issue.
Then there is a woofer rattle, which could be caused by a woofer spider coming partially unglued -- which can be fixed by a good speaker tech, without driver replacement.
And then you could have a cabinet rattle, caused either by the "variable porting" rails not being snugly fit/secured (which is almost always a problem on Canterbury), or by some other wire or loose component getting energized in the cabinet and banging against a neighbor surface. The latter can be difficult to track down, but easily fixed if discovered.

Would you describe the tweeter ringing or static as sibilance? I've noticed sibilance on vocals is a bit pronounced with my Cheviots. There is also ringing, but I would say it is recording dependent. I'm starting to think it's just a characteristic of the speaker...just doesn't gloss over the sibilance.
