Default Refoam of f113

I recently acquired a used f113 that must have been really abused by the previous owner.
I'm considering replacing the surround foam the driver myself, because of a large rip in it.
I was curious if any of you have tackled this task, and would like to hear your thoughts / story.
Looking at the way the driver is installed, it appears to me that complete disassembly would be required...
Any thoughts?

I’ve reformed several drivers. Not difficult, more tedious that anything. The hardest part is finding the appropriate surround. If you can get one from JL you’ll be miles ahead. Then it’s removing the old surround without damaging the cone. That’s the tedious part.

Now I use a local company that rebuilds drivers, mostly musical instrument ones.

If you are not concerned about appearance, you can use a flexible silicone adhesive to repair the tear in the surround.

I have the confidence in myself to perform the refoam,
I guess my real question is how to remove the driver from the cabinet, besides exploratory surgery...

There are a few you tube videos on how to do this. It doesn't appear to be to difficult.

I've watched all of the videos that I could find, and have reformed speakers in the past. So I have accepted the challenge of repairing the driver.
I'm assuming I'll have to remove the amplifier off the rear, to get to the fasteners....

Have you looked thru Dan's thread on working on the F113? May be some useful info on the amp removal, etc.

I always thought of a subwoofer cone like your best friends girlfriend; you don’t touch it! All kidding aside, after watching the re-foaming video I had no idea how robust the components of the subwoofer appear to be. He wasn’t too bashful about handling any of it. It was interesting to watch and see how you take everything apart, and put it back together. Thanks for posting....
