Congrats, Enjoy
Return option is an excellent option when buying used, and TMR ought to be a safe source, and you already know you like the sound of that maker’s speakers.
I would have a plan to improve the visual condition before parting with $5k, then how much I was daily aware of enclosure damage, they might get ’fixed’ soon or never.
i.e. a scratch or ding on the passenger side of my car will wait until a ding on my side, then they get fixed.
Not these, but if wood veneer, a damaged enclosure, or perfect but ’not special’ i.e. common wood veneer, can help lower the purchase price and make it easy to have a local woodworker clad them in something special.
for someone who knows how amazing these sound when ’right’, this $750. can lead to a wonderful looking renovation, better than the fairly common walnut or oak veneers the factory used.
I'd change them to 1 rear wheel, centered, with anti-tipping blocks in the corners, that's more weight per wheel, and 3 never wobble, so movement, alternate toe-in is easy.
