    Anybody know of an online resource that shows you how to to do simple speaker repairs with rubber cement, etc? I have two speakers that need fixing.

    On one, the paper dustcap is starting to pull up, and it buzzes at volume. The other speaker needs to be examined more closely, but it's obviously been patched before, around the dustcap (the speakers are from the 80s). It also buzzes, so I'm guessing that it has the same problem, but the previous fixes may complicate things (or not?)

    I don't want to make a hash of this - I know I can fix them, but I'd like to do it using 'best practices'.

    If there isn't a guide online, well I think there should be...

    Bump... I've seen several threads about this, with recommendations to use cigarette paper, dryer sheets, toilet paper, silicon adhesive, rubber cement, Elmer's glue.

    Is there an authoritative guide for this, online?

    i don't know of an actual 'guide' but as far as glues for the dust caps, i use the black stuff from orange county speaker. and for tears in the cones, i use their white adhesive since it remains somewhat flexible (and it dires clear).

    I'm curious what kind of overlap I would make (how big) if I used a patch, and whether a patch is even necessary, whether to skimp on the glue or not (I will probably use rubber cement unless I'm told otherwise) and that sort of thing. In other words, some details.

    Thanks for the reply, I will check out Orange County speaker,

    YIKES!!! speakers from the 80's? there must be a point where they are just too worn out ??

    Many repairs will only give short term satisfaction, not so bad around the dust cap though.
    Check the speaker cone travels in and out without 'any' friction or scraping, if it is rubbing, they are stuffed, only a matter of time before the voice coil shorts out and takes your amp too.
    Hopefully only the lose dust cap is causing the noise, and it can be glued with expoxy resin, just don't use rigid glue on the folded outer rims.
