Or even send it to a place like a Speaker Shop - they can re-cone it.
Did a very good job for me.

Why spend $40 reconing a speaker when $.40 worth of glue will do the job? There is a sticky thread on here about repairing speaker cones by a guy named Syl, he uses dollar store glue pens, I've tried that and it works well, I've also tried general purpose contact cement and it works well. However the glue used in glue pens is water based so if you need to coat a large are it is advised to shim between the voice coil and the pole piece to keep the cone from warping out of allignment. Whatever you do don't use sillycone no matter how many times you read it, silicone is for sealing bathtubs and around windows not fixing speakers.
