I recently purchased a pair of Polk SDA 1C speakers that seem to be in as new condition. Not a mark on them and in the original boxes.
For those unfamiliar with these behemoths they weigh in at over 40kgs a piece and 1.7 metres tall.
They have one 12" passive radiator, four 6 1/2" mid/woofers and two dome tweeters each. They are built like tanks and need plenty of room.
The SDA stands for Stereo Dimensional Array, they have an interconnecting cable that plays the opposite channel out of phase for two of the four mid/woofers.
How do they sound:
In a word amazing, they fill the room with the biggest sound stage you could imagine, I am literally on the edge of my seat listening to these things.
Voices seem to hang in the air, instruments sound like they are in the room with you. It's hard to grasp that the sound is coming from two boxes 7 feet apart.
I put on Comfortably Numb by Pink Floyd on vinyl and I felt comfortably numb, the detail, clarity and separation is outstanding. Noise floor is lower than I have heard and distortion almost non existent.
My room is nearly 20 feet wide and that is how wide the sound stage is but that's not all it encompasses you, going from front to back as well all from just two speakers at the front.
These speakers are very good even without the interconnecting cable, but with it they are magical.
If you get a chance to listen to these grab it and see what you think, you might be surprised by these vintage speakers.
Here's what they look like:
