Polk Audio - Stereo Dimension Array- interesting technology. Bad timing. Came out in the early 80’s I believe. Eliminated intermodulation crosstalk to create true stereo imaging so the left ear hears the left speaker first and so on.... The speakers were huge and retailers were reluctant to devote the space as the industry was moving towards smaller footprint speakers. Plus, they needed near front wall placement but lots of space to the sides for the SDA technology to work.
Tech That Flopped!
Every few months someone releases technology that seems to be revolutionary, but goes nowhere a couple of years later. Some tech gets acceptance and even imitation. Some goes wildly successful.
