Infinity RS-4.5's need some help

I’m a new member here...
   Following the death of a family member who was something of an audiophile, I’ve ended up with the bulk of his gear including a pair of these monsters. Visually, they look great - the cabinets are in very good shape, front grilles are good, but the foam under the grills on the face of the cabinets is indented in a few places. I have not powered these up (I have the amps he used) for any sort of testing, mainly because the foam surrounds on all four woofers is shot, and I don’t want to cause any more damage. I’ve replaced foam on an old pair of Cerwin Vegas but I’ve done enough research into these speakers to know that these Watkins woofers were pretty special - not something I’d be comfortable taking on.
   We really don’t have the room to use these speakers (6 feet tall, 3 feet wide, 300 lbs. apiece) - or the funds required to re-foam professionally, so we’re leaning towards selling them. I guess my question is should I sell as-is or make the investment to have them re-foamed first - maybe by Watkins himself? I’m also a little concerned about the Quatre amps he used - I’m sure they will also require a thorough going over - more expense.
   He was the original buyer and I know he loved and babied them but as he got more and more sick, they fell into disuse and just sat in his living room. I’m sure he’d prefer to see them go to someone who would enjoy them as much as he did, and I’m afraid that may not be us.
I’d appreciate any thoughts...
