    Default Identify these vintage 8" Alnico drivers.

    Two vintage 8" Alnico magnet bass/mid drivers from a pair of speakers I built over forty years ago and I can't remember what they are. If you know, tell me. My initial thoughts are maybe Isophon, they have that German look about them and look to be high quality.

    They're not white, the alloy is matt finished like a sand casting.

    Yeah, could be Russian. They've made some good speakers. Actually, I seem to recall these may have been used in Decca's own speakers, they used a variety of makes including their own..
