I stumbled across 4 of these in my neck of the woods for $5. From the pics, they look rather nice. All I could find on them is this: Google Translate Does anybody know anything about these? What type of cabinet would be ideal? They appear to be coaxial, with a range of 50 to 14KHz. Interesting looking speakers for sure. The current owner used them as ceiling speakers in his basement for the last 40 years, and has since refinished it. Do they look like good candidates for OB use?
