I am selling these from my personal collection. I have owned and used these regularly for approximately 7 years. They are still being used, but I have too much equipment and something needs to go. These are in extremely nice condition and sound excellent. Enclosures and grills are near perfect. These are the 2nd generation with the single tweeter, which are known to be the better sounding generation. These have the original interconnect cable and boxes. I am listing as local pickup in Southern, NH, approximately 1 hour from Boston. I will consider shipping as well. Please keep in mind that these are boxed separately, so shipping will be double.

Great shape . Maybe signs of minor dust on them .

Incredible sounding vintage Polk SDA Reference Compact Speakers. Selling from my personal collection and truly hate too. Just have too much equipment and need to downsize. Look and sound great! These are 2nd generation with the single tweeter for better sound. They come with the original interconnect cable and boxes. Listing for local pickup in Amherst, NH, approximately 1 hour from Boston. I am willing to ship, but please remember there will be 2 boxes and thus double the shipping cost.

You can install carpet spikes as well. They show some nicks and such from age. Pick up only as these are almost 100 pounds a piece.

Tweeters have been tested and are in good working order. Both produce nice clear sound and measure 6.4 & 7.0 ohms. They were pulled from a pair of SDA-1 speakers. Look at the pictures and feel free to ask any questions.
