Last time I switched speakers in my Fender DRRI I let one of the sharp screws puncture the speaker. Well, it didn't cause any trouble for the next few gigs, but recently it's started to buzz. Do I need to re-cone the whole deal or can I do some kind of patch job here?
Superglue is very brittle. There are special industrial formulations that are used for voice coil attachment and such, but still wouldn't work very well in a flexing environment like the middle of a cone.
The old school (or "ghetto" as my kids call it) way was with tissue/toilet paper and white glue. Usually on the face of the cone but sometimes on both sides.
Actually, I know a young, starving bass player who kept his 2-10 SWR going for a couple of years by reworking the speaker surrounds this way every few months.
Yep...direct from Ted Weber...Elmers glue and tissue paper...saturate the tisse paper with the glue...smooth out all wrinkles and let dry...do 5 layers...if the tear happens in the doping material...first remove the doping material with acetone and then do the above proceedure...
