The 'fix' it would require a recone, which involves removing the soft parts and replacing them (cone, surround, suspension, etc). Some manufacturers sell recone kits, some only do it themselves, some offer no recone option at all. Im sure ID has a recone option of some sort, but what it is I do not know. Call them Monday (AWESOME people... unbelievable customer service) and ask them yourself.
With that said, I agree with the guys above, fix it yourself. The actual hole is only in the cone (not a moving part like surround or spider) so it can be filled rigid without worry. Apply tape to one side of the hole (for a backing mat'l) and fill the hole from the other side using various glues, epoxies or resins. It wont be as pretty as a recone, but it'll perform just as well and be alot cheaper.
