Companies that repair/refinish speaker cabinets?

@OP,
I have shipped and bought many speakers shipped from around the country, and, I have never had an issue with damage (thankfully).
Though all the speakers were shipped in their original boxes.
Sorry to hear of your situation, but, in my opinion, it is an exception.
And, if they were shipped in the original boxes, I would contact Acoustic Zen and let them know of your issues. Perhaps they need to add some additional padding? 
At least it might help future owners.

I would at least call Salk Sound. He may or may not be willing/able to do the refinish work but I bet he could at least point you in a proper direction.

Mission accomplished!

@bryhifi  Your suggestion for Shoenbauer worked out, easy to deal with and, after emailing and calling at least 18 different companies, they actually responded quickly and professionally.  

@ruraltom ,
Glad to hear that they worked for you and mission accomplished. 
Hope the proposal meets your loss evaluation and makes situation fiscally tolerable. Damage to finely finished speakers is always painful to live with.
