These speakers are in good cosmetic and working condition. They are huge!! Theyre around 5 feet tall and super heavy. It will be local pick up only because of the sizes. They will come with speaker wire for each cabinet and the connector cable. On one of the speakers the side is coming off, I think that happened in transit. Easy repair with some wood glue. Please see photos for more description. Everything in the pictures will be included. Please feel free to ask any questions and throw me an offer.

Up are a pair of Vintage Polk Audio SDA SRS speakers, both right and left channel. These were part of my father’s hifi system and were originally purchased in the late 80s or early 90s. These preceded the SDA SRS 1.2 and SDA SRS 1.2TL. The system was taken apart in April 2023 and were working at that point. The speakers have been in a cool, climate controlled storage space since and I currently have no way to test so this is an “as-is” sale. Photos are of the speakers up for sale. Per Speaker Tweeters: 4x SL2000 Stereo Driver: 4x MW6503 SDA Driver: 4x MW6503 Bass Radiator: SW150 Crossover: BE2000-A Comes with the ~20ft blade/blade interconnecting cable. Visually, these are still in great shape, with only some minor blemishes. These were rarely moved at all once installed. Absolutely local pick up only from the Rockville, Maryland area. If you are looking at these, you probably have an idea of how big and heavy these are 5 ft 4 in tall each and 150+ lbs per speaker.
