These are in nice working condition. These were partially rebuilt — Tweeters are new, and were replaced with reproduction tweeters of the same technology and specs as the originals (which were both toast). I also replaced the linen on the grill as the original was dirty looking. Finally, I de-oxidized the audio crossover components, replaced the wiring, and re-soldered everything inside. The original insulation was in good shape so was re-used. Midrange speakers are also original and sound great. Some wear on the cabinets — please see pictures. These are from the 1960s so are not cosmetically perfect, but they sound great. You can also pick them up in person for free near Boulder, CO.
