Quick ID please. The BA 150 picture is a what? Late Series I or a Series II? The alignment of the drivers as a way to tell is not clear to me. The round SEAS tweet, it doesnt have. So? Any guesses. Thanks folks.
Series II, I think (square tweeter, but still has the paper woofer cone). Those look just like mine when I got them, gave them a refoam and they sound great.
