For the first time in nearly 25 years, Polk is introducing a new SDA speaker the Polk Legend L800. The Legend L800 floorstanding speaker features new patents that build on the original SDA mission of maintaining full stereo separation all the way from the source to your ears. As a result, L800 renders the most lifelike detailed, stereo imaging you have ever heard from Polk. The speakers seem to disappear as the sonic images fill your listening room with startling realism. It does this by minimizing the inherent distortion found in all stereo speakers known as interaural crosstalk (IAC) by utilizing a second column of transducers called a dimensional array. Conventional speakers restrict what you hear due to their failure to maintain complete stereo separation from the source to the speaker to your ears. The new dual 1 Pinnacle Tweeters add incredibly clear highs whereas two new Turbine Cones mid-range drivers deliver a detailed, smooth mid-range in the critical listening area. Dual 10 woofers, and the addition of the newly revamped Enhanced Power Port, delivers unmatched clarity, balance, depth and detail. The Legend L800 speakers are the most revealing and best sounding SDA speakers Polk has ever made.
