What to do with my dad's old Revel Performa F50's?

Hi friends, so I recently picked up my dad’s old Revel Perfforma F50’s that were taken from his home theater setup (along with a C30).

I’ve had a few interested parties come by to take a look and think about buying them, but ultimately they decided to pass as some of the rubber has cracks in them. Now I’m wondering what the best course of action would be. Trying to balance not throwing them away vs spending too much to ship them off to get repaired/restored for sale. I’m moving soon so probably want to try to get rid of as much as possible before the big move and just wondering what you all would do in this scenario?

Here’s a link to the selling post so you can check out all the pictures. What should I do here?
