well.. it all depends on
1 - what sub is it...??
2 - In what manner is it damaged...??
3 - Is it covered under warranty...??
4 - Is it a feasible project to repair it...??
5 - Does it need replacement parts if yes then are they available in the market or from the manufacturer..??
6 - Is the manufacturer ready to repair it for you charging a certain amount..??
7 - After going through all this, is the sub actually going to perform well for the price you spend in repairs..??
Please consider all the above questions, try contacting the manufacturer and give us more details.
Help us help you...!

Right on target as usual Vic... repairing subs are doable if we have patience, the right tools and the proper parts as needed.
A good recone job can be very expensive. If the subs mentioned are not worth $80/ea to repair, better to take them apart, figure out what failed and then learn not to abuse them to the point of failure when replaced.
Fixing them depends a lot on available parts and the skill/knowledge to repair them well. It's a delicate operation in some ways, but doable if we can get the right parts.

What kind of amp are you powering these puppies with? Judging by the "locked up" status of the subs, and the power these monsters (especially the Dub-7) require, I sreoiusly doubt thewy were powered properly, and probably burnt up the coils from excessive clipping, and caused the voice coil to jam. There is no fix for this that I know of, but you may be able to contact the manufacturers to get a recone. This is an expensive repair, and may not be worth the money required, but the JL is one expensive sub, and may be worth the recone.
Let us know the model # of what amp you are using, so we know how much power these subs are getting.
FYI....A sub does not just "lock up". Their is a cause for this, and generelly it is a melted or burnt voice coil that is stuck in the magnetic gap. We are not talking about a safe here.....but it will cause the cone to become all but impossible to move along the gap......

It is best left up to the manufacturer for repairs of that nature & expense especially on high cost gear. Usually the consumers mostly tackle minor jobs like foam/ rubber surrounds, dustcaps, resoldering tinsel leads and such. Even some of those can be tricky as coil alignment is very important.
There a few speakers that actually are designed for field repair if necessary because these unit's cost are so high, the manufacturer knows that they will be reused rather than junked. Cone/surround/coil assemblies are sold in kits along with special attachment techniques that make repairs quick and precise.
