This Speaker was from a Zenith 12U159 cabinet. VINTAGE 1936 ZENITH RADIO 12" SPEAKER WITH TRANSFORMER 49-150AB The speaker is 8 ohms and the transformer / field coil was tested with my Fluke Multimeter as shown in the pictures. There are no rips or holes in the cone, the frame has surface rust, dirt, wire is original and has some cracking but still good. It will be packaged well.
