HISTORY OF STEREO DIMENSIONAL ARRAY (SDA)

The original SDA technology targets a phenomenon known as Inter-aural Crosstalk. It’s a fundamental problem not only for stereo reproduction, but also for any system with more than one speaker. Polk Audio was the first to think of dealing with the problem acoustically in the listening space. By positioning additional drivers to deliver a precisely derived cancellation signal to your ears, SDA enables you to hear the sonic image just as the recording captured it. Individual instruments appear across a wide stage, as if the performance were in front of you at that very moment.

SDA TODAY

We’ve ushered our patented SDA technology into a new era, fitting it into a smaller form factor found in the MagniFi Mini and MagniFi Max sound bars. Instead of using the passive crossovers in our towers-originally designed for a two channel audio signal-we use digital signal processors (DSPs) in the sound bar to drive the SDA experience in your home. In addition to processing two channel audio, it also provides the listener with 5.1 surround sound and is compatible with our modern decoding technologies, Dolby® and DTS®.
