Polk Audio SDA 2 Tower Speakers Stereo Dimensional Array Loudspeakers •Mid 1980s These are excellent sounding high end performing vintage speakers. I am the second owner of these, but it is time to downsize and pass them on to the next audio enthusiast. Aesthetically they are in amazing condition. Grills are free of snag, rips, and tears. The cabinets are pristine with no scratches, chips or dents. Please review all photos prior to purchase. I will also be more than happy to demo them. The videoclip does not do this justice. The SDA-2A was directly designed by Matthew Polk during the era when Polk was making true performance loudspeakers. The SDA technology involves combining two speaker systems in each cabinet of a mirror-image stereo pair. The inner one (nearest to the center of the room), called the stereo array, is a normal stereo speaker. The second system, known as the dimensional array, is located a few inches to the outside of the stereo array. Each dimensional array is driven by the stereo signal from the opposite speaker in the pair, and the frequency, phase, and amplitude characteristics of its output are modified so that when its sound reaches the ear of the listener, it cancels the sound arriving at that ear from the opposite speaker. The result, in the ideal case, is that each ear hears only the sound from its corresponding speaker, without the interaural crosstalk, and consequent spatial distortion, that would otherwise exist.The speakers have a unique sound characteristic and lets them present a huge soundstage. One reviewer stated the SDA 2As measured the flattest overall response of any speaker they ever tested.They are exceptionally well cared for and play loud and clear. The SDA cable is included.
