These were a Craigslist find from the Detroit area. I'm now a Saba "junkie", which is bad as Sabas were never imported to the United States. I couldn't find much information on the Internet regarding these particular speakers. If you know the model number or date of production, please e-mail me.
The "story" that goes along with these is they belonged to the seller's friend, who was stationed in the US Military base in Germany. He brought them back with him. The seller believes they date from approximately 1959. I crossed my fingers when powering them up that a voice coil hadn't been damaged. My fears were alleviated when they began singing like angels. Amazing sonics.
