Vintage Speaker repair?
Wondering if anyone here has attempted to fix 1930s-1950s speakers with dried out glue. What sort of solvent will soften the old stuff, and what sort of glue do you prefer to use? Am thinking about using solvent to detach cone and spider, and then re-glue to cure buzz problem.

Get the glue used for speaker re coning
In the music shop that I worked and recently have gone back to part time Pa and high end home speakers are being re coned or having the surrounds replaced. JBL, Cerwin vega, Bose and other suppliers used a sticky glue that dries semi hard. A very important note! the shops master re cone technician never used silicone glue and would refuse to take in speakers that were re glued with silicone.

So the sticky glue which fries semi hard.. Does acetone cut it? I had mixed results on an oaktron 12", acetone softened the glue holding the dust cap but didn't touch the glue holding the cone in place. I've read that toluene, and MEK are both capable solvents, and also isopropyl alcohol. I want to get my hands on some toluene and check it out... My intention is to non destructively remove the cone for later reuse.
That sticky glue that dries semi hard sounds like PVA, which is what a lot of people seem to recommend.
