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.

Legendary Polk SDA II speakers with interconnect cable. Polk’s line of Stereo Dimension Array (SDA) speakers, which were designed to create a more natural stereo sound stage than is possible with conventional forward-facing speaker systems. The SDA technology involves combining two speaker systems in each cabinet of a mirror-image stereo pair. The inner one (nearest to the center of the room), called the “stereo array,” is a normal stereo speaker. The second system, known as the “dimensional array,” is located a few inches to the outside of the stereo array. Each dimensional array is driven by the stereo signal from the opposite speaker in the pair, and the frequency, phase, and amplitude characteristics of its output are modified so that when its sound reaches the ear of the listener, it cancels the sound arriving at that ear from the opposite speaker. The result, in the ideal case, is that each ear hears only the sound from its corresponding speaker, without the “interaural crosstalk,” and consequent spatial distortion, that would otherwise exist. Eliminating interaural crosstalk effectively removes the physical speakers as apparent sound sources. SDA-2 is a superb speaker regardless of its spatial characteristics. Im moving and cannot take them with me because of the size and weight.
