Found them very helfull also on all matters before.
If they pre date their drawing records, then if the can gauge what type of wood cabinet they are they can give a good guestimate as to the right kind of bonding glue for them, or another double jointing method of glue and glue tape.
I rang Mike Creek @ Epos, he suggested it was a very difficult job, due to the dual suspension. But I'm going to try putting a "tube" of xray film down the inside of the voice coil, around the pahse plug (for protection).
Then, a small amount of super glue with activator around the base of the cone.
Interestingly he mentioned a new pair of Epos Encore 20's which might be a suitable replacement for my 14's, which will be on display at silverstone ent of Sep '10.
You do know that the phase plug unscrews, don't you? I used superglue to reattach the mid/bass cone of one ES14 speaker many years ago (more than 10, I think). Still works fine - and I can not tell which one it was.
