You should use a meterial that is somewhat flexible. It was suggested to use chamois for the outside edge of the cone. Pliobond is a good adhesive but others will work.

:Hi: I have an AK F4 speaker. The cone itself is in perfect shape and it sounds excellent. The outside edge of the cone has a paper surround that connects the cone to the metal speaker rim. The paper has dried out and is missing in several spots where it is no longer atached to the speaker rim. It looks repairable but I want to check on suggested replacement material for the paper surround and glue or adhesive that can be used along with any tips you might have on removing the old and replacing the new. Great forum! Thanks. Al

:Al,
:Some have suggested KID LEATHER as a surround, but would guess it costs more than a Chamois. I made a cloth roll for an Edison speaker, because small remnants of the original looked like old deteriorated cloth, but found out later it was supposedly KID Leather. In my case, and without any pictures whatsoever, molded it with a roll and flamges each side for cone and frame from a single piece of cloth. The beauty of cloth is, it can be wet, then placed over a mold, dried in a low heat oven, and will retain the roll or curvature when dry, and still be flexible. If you're not concerned with originality, there are several widths/thickness of plastic/rubber foam tapes available, and some with glue on one side.
:I use a waterproof (but water based) fabric glue that dries to a clear flexible consistency, somewhat like silicon rubber in tubes. It squeezes from the bottle like a paste, but can be watered down, and applied like paint with a brush

With my Majestic 180 speaker, where I originally got the idea, I used four pieces of thin suede. The original was rubberized cloth. It was stretched flat, so I did the same with the leather. It works well, though a roll would allow for even more movement. As it is, the radio has surreal bass. It's incredible. For any other speaker that I've repaired using leather, I've used it flat, too, and it works alright, but it limits the travel somewhat for those really loud booming passages. A roll would allow more uniform speaker movement over the majority of its travel.

:Nice idea! I suppose I could mold cloth that way, especially if it has been rubberized.
