I was a bit suspicious about the glue I'd used for the woofer EPDM (synthetic rubber) couplers. The glue (Evostick "Sticks Like ...") just didn't seem to be setting where it was in contact with the EPDM, and some investigation today proved that it was useless. A quick Google on EPDM revels that only cyanoacrylate (superglue) really sticks to EPDM, because it's slightly oily, being made out of, well, oil. The next best stuff is acrylic glue - and at that point I recall that the Magic521 kit includes some acrylic glue...
A quick scan of the Magic521 instructions reveals they are supplying Soudal Fix All, or at least, that's what I worked out after some judicious Googling. And Screwfix has various types. Hurray.
An hour's worth of pulling apart and careful scraping cleans up the couplers and the mounting rings. At least, I hope it does. It's hard to know. And I do have to be careful because the speakers are of course still glued into the mounting plates, and are easily damaged with a scraper or screwdriver blade. I have managed not to damage them, unusually.
So tonight I've reglued the couplers and mounting plates, using Soudal Fix All High Tack, which is incredibly thick and hard to use. It is, however, clear, which is handy, and smells a lot more pleasant than the Sticks Like, being solvent-free. Let's see how these look tomorrow.
UPDATE: The new glue appears to stick really well! Success. Phew.
