Such difficult speakers to pin. It seems like they are one offs. They sound great. Such incredible sound. Im too nervous to remove the speakers to get a proper look. Ive had someone look through Dallmeyers archives but these weren't found. And Cinaudagraph don't really have much of an archive. I know rudy bozak worked for Cinaudagraph for a while, but i cant find his archives. Thanks for the help everyone, i cant wait to finally find out what they are and who built them
