$150 OBO

I am not an expert on Rola speakers but I think this is a 1966 or 1959 Rola Alnico 12" speaker
Please look at the codes and do your research
8 ohms I think -  it's the original cone and works really nice
I've read these might a version similar to a Jensen P12N
Heavy magnet so should be able to handle a few watts, maybe 25-30 watts - probably not suited for more than that
