The serial numbers are very close, 03353 & 03355, and currently do not work properly (toasted pots and possible bad crossover caps). When tested, only the woofers play when connected to the terminals on the back. I removed the grills to test the mids and tweets, they do produce sound with a 1 kHz (on midrange) and 10 kHz (on tweeter) test tones applied to the solder posts on the leads going to the mids and tweets. The cabinets are solid but do have some scratches and marks, no split seems, and all the drivers work, the grills with badges will be included. This may be a great restoration project or may be used as parts for other projects. The woofers have the cloth surrounds with the damping rings in the center of the woofers, see pics, and the midrange have the phase dampers attached on the center of the grills, also see pics. No drivers have been removed to see and driver dates or serial numbers. The speakers no not have a musty “basement” or “storage” smell and have not been sitting in a wet place, dry in the closet storage only. The speakers pictured are the ones you will recieve.
