Vintage KEF B139 / 6171 Oval Woofer Driver Made in England - I have no history on these speakers, or what speaker they were taken from, as they were part of a larger parts purchase.
DALAUDIO tested resistance measured 7/18/24- 6.45 Ohms / 6.59 Ohms coil DCR - Left and Right matched pair. This pair have the second generation, coil install on white paper and the magnet has 3 screws, (late 1960s) type cast frames. They both "work" and have been tested with actual audio signals. Surrounds are intact. Front skins have typical minor scuffs per photo.
