They were presumably made in West Germany, most likely some time in the 70s. The material is solid wood. The brand is NOT "Pöhler und Schilling" or "P+S" despite looking very similar. There are no other logos, text or stickers on these things.
Any help is greatly appreciated!
Oh no way! That's it! Maybe it's a sub-brand or a very early logo. I could only find ones with the square text badge. Thank you for solving this mystery for me :D
Idk if I did, it just seems that way.
I edited by previous reply a bit, maybe compare the drivers to be sure.
Also, they are old speakers, maybe they had some woodwork done over the decades.
The drivers are in fact different, but the ones in your links are also not matching. Maybe they experimented in the early days of the company or they were customized. I consider this one solved.
