Great shape . Works great.

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.

Polk Audio SDA - Restored Vintage Floor Speakers For your consideration is a pair of restored, tested and beautiful sounding Polk Audio SDA speakers from the mid-1980s. Specs: Dimensions: 12 D x 16 W x 43.5 H Weight: 85lbs each Resistance: 5 Ohms Max Wattage: 400W LOCAL PICKUP ONLY! I SPENT SO MUCH TIME AND MONEY ON THESE SPEAKERS THAT i CANT RUN THE RISK OF THESE GETTING DAMAGED FROM SHIPMENT. i USED TO WORK FOR A SHIPPING COMPANY SO I KNOW FIRST HAND HOW PACKAGES, EVEN FRAGILE PACKAGES, ARE HANDLED. ITS NOT PRETTY. NOTE: feel free to message me and Ill provide a link for an video/audio sample link on my YouTube channel. eBay will not allow me to post it here. This restoration project took nearly a year with nearly 200 hours invested, and I feel they look and sound spectacular. Do they look brand new??? NOPE, if youre looking for brand new then go to Best Buy, BUT youd never know these are 40 years old. Plus, these sound better than most store bought speakers that you can get today. A lot of it has to do with the expanded sound stage created by the SDA (Stereo Dimensional Array). The restore/repair work consisted of the following: 1- Stripped, stained and applied 6-9 layers of poly to the front, 2 sides and top. High gloss piano finish. 2- Replaced the torn grill fabric, painted the grill frame and added new top-of-the-line grill fabric. 3- Bench tested all drivers and crossovers - All functioning 100%. 4- Patched, sanded and painted the base black 5- Made a custom interconnect cable.

Tweeters have been tested and are in good working order. Both produce nice clear sound and measure 6.4 & 6.7 ohms. They were pulled from a pair of SDA-1 speakers. Look at the pictures and feel free to ask any questions.
