This link to a Loctite brochure on (trade) adhesives for speaker driver manufacturers, which I just saw posted at AK, is certainly interesting... so I thought I'd provide the link here, too.

    Nice info. Loctite's table shows that to attach surrounds to woofer cones/speaker frames, cyanoacrylate (super glue) is the adhesive of choice.

    I'll have to file this for future reference in case I my screwdriver has another close encounter with a butyl rubber surround :cheesygrin:

    Super glue (cyanoacrylate) really is not good at the flexing part of the butyl rubber...I also read this and was quit amazed at the amount for lack of a better word "superglue" in their listing. I'm betting it not the superglue we buy at the store in the little container......but then again who knows.:mrgreen:

    Actually (cyanoacrylate) is what Super Glue or Krazy Glue is made of. And yes they mean the little tube one.

    There are multiple flavors of cyanoacrylate adhesives... but indeed AFAIK most set up pretty rigid, even brittle.
    Had some experience with the better CA adhesives during a brief father-and-son foray into RC aircraft some years back :-)

    The stuff I used to repair the hole in the surround of my now backup 6510 is by Loctite and it's called something like Ultimate Super Glue. The bottle says it remains flexible and is ideal for repairing stuff made of rubber. Haven't actually tested it yet. Bought it at Lowes.

    Loctite, and probably other companies, have different formulations of the stuff for different applications.
