SDA-PRO Technology with 15-Degree Baffle Offers "True Stereo": Polk Audio Legend L800 Tower Loudspeakers Deliver Source-to-Ears Separation, Lifelike Imaging, Pinpoint Accuracy
Polk Audio's iconic Stereo Dimensional Array (SDA) tower loudspeakers return for the first time in nearly 25 years in the form of Legend L800. Able to provide among the most pointillist-detailed, lifelike imaging and source-to-ears separation any audio component has ever managed, L800 disappears as your music takes center stage. Featuring SDA-Pro, L800 delivers "true stereo" – defined by acoustic isolation of the right and left channels, leading to pinpoint accuracy, unblemished clarity, and three-dimensional soundstages that hit on height, width, and depth. You've literally never heard another speaker like L800 because none with its engineering and approach exists.
L800's wish-list features begin with patented SDA-PRO technology, replete with a 15-degree baffle that angles both the stereo and dimensional arrays. By angling the baffle, Polk Audio greatly enhanced the quality of the stereo arrays by aiming them more precisely towards the listener – just like you would when toeing-in speakers. The configuration also allows for a narrower speaker while maintaining the correct width and positioning of the dimensional array. To augment interaural crosstalk (IAC) cancellation, L800 improves the bandwidth of the dimensional array to more completely match the relevant frequencies of IAC via paired tweeters and paired midwoofers. In addition, L800 employs special "Head Shadow" filters to match (and hence, cancel) IAC.
As for the active mechanisms, let's start with the dual, one-inch, high-definition Pinnacle ring radiator tweeters. Developed in-house by Polk Audio, they convey ultra-clear, crisp highs without unwanted coloration or distortion. A finely tuned waveguide dramatically improves the dispersion of high-frequency energy, ensuring a broad sweet spot all the while a critically damped rear chamber helps to defeat unwanted resonances.
Created specifically for the Legend Series, dual 5.25-inch turbine cones ensure irresistibly natural midrange responsiveness. By merging Polk's proprietary foam core and molded turbine geometry – architecture that increases stiffness and damping without adding mass – the combination plays with a smoothness that extends to its effortless low-end reproduction. Speaking of the latter, dual 10-inch, high-excursion, long-throw woofers further deliver deep, tight, bass for music and movies. And an enhanced Power Port transitions air flow from the speaker into your listening area for louder, cleaner playback while minimizing turbulence, distortion, and port noise.
Of course, even the finest internal build would suffer if a speaker lacked proper enclosures. To wit, Legend Series employs real wood cabinets complete with braces and enclosures that drastically lessen internal standing waves. Adjustable feet, large five-way binding posts, anti-diffraction magnetic grilles, and an interconnect cable to connect the speakers also come standard.
Free of DSP or processing, and Hi-Res certified for high-resolution DSD and streaming, L800 arrives prepared not only for high-end audio pursuits but immersive home-theater formats such as Dolby Atmos, DTS:X, and IMAX Enhanced. A five-year limited warranty with a five-year extension with product registration – and our 100% Satisfaction Guarantee – practically does everything but unbox L800 when it lands on your doorstep for a risk-free in-home audition.
"In many cases I was enthralled by what I heard, and I can say with confidence that anyone else who experiences the L800s will have a great time listening to their collection with fresh ears and a fresh sense of purpose. Polk Audio clearly packed a lot of history, effort, and love into its new statement speaker, and that high level of enthusiasm is reflected in the sound."
