Utah speaers

I picked up and sold prematurely these Utah speakers. By the time I listened to them, a buyer was already at the door. I would like to find another pair and put them into my rotation for a more thorough listening since I was blown away/surprised how they sounded. 

What is the MODEL so I can start looking for them?
