What does the SDA technology do to improve the sound?
The patented stereo dimensional array technology derives from an original technology called Inter-aural Crosstalk, which is a fundamental feature for any system with more than one speaker. It is also useful for stereo reproduction. Polk Audio was the first brand to think of the room as its own acoustic space. The SDA technology comes down primarily to driver positioning, which is paired with a cancellation system that allows you to hear the audio image in the same way that it sounded when it was recorded. This technology also allows for a broad, symphonic sound like you would hear in a live performance. After the success of the Polk Cabinet speakers, Polk has expanded the use of its SDA technology into soundbars and other smaller applications, including two channel systems.
