In the past week the bookshelf version with stands (stands are expensive) sold. Advertised $3.5K. Not sure they sold for. They are not efficient so need powerful amp(s) to drive them. Plus factor in the cost of jumper leads if using single amp i.e. not bi or as designed tri amped.
I think you could advertise for $5k so sell fairly quickly or $7k if willing to wait and if don't sell drop the price.
Agree would have loved these as a wedding present!
Hope that helps seller or buyer.
