JL Audio's only infinite baffle subwoofer has a butyl rubber surround. And rubber is tougher to glue than foam. I would call JL Audio directly and see if they can recommend a glue that you can apply yourself in the field. Clean up and prep would be important. Clamping would be important (which seems difficult on the cone side rather than the basket side).
That's a domestic built sub so perhaps JL can repair it for you. Also, Parts Express sells re-coning and speaker repair kits. Maybe they can sell you the right glue for rubber to a polymer cone and provide some instruction. There are speaker repair facilities all over the country. Freeman Tuell (or something close to that) here in Dallas, Texas. If a 4" span has failed then I do not trust the remaining circumference long term. You might have a pro do it.
