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.
