Andre,
Thank you for both the warm welcome and the help in deciphering the details of these speakers! I’ll use the link/site you provided to research them further. And I just found the serial number/code on the edge of the enclosure/cabinet “5 6 S 6 2 7” They sure look good, and I’m going to find a replacement Klipsch badge missing on one of the speakers. Plan on enjoying these for a long time!
