These are Monoprice #24456, purchased new by me in September of 2018. Original packaging and paperwork. No operational issues, just a change in audio direction. Sold only as: a pair, for cash, local pickup from ZIP 18661[northeastern Pennsylvania]. $650.00 for the pair. Packaged weight is 73 pounds each! The one photo shows the setup that I had used these in.
Thanks for looking.
