Legendary Technology Returns

True Stereo

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. The Legend L800 speakers are the most revealing and best sounding SDA speakers Polk has ever made.


Polk SDA speakers were the first true stereo speakers because they were able to maintain stereo separation all the way from the source to your ears. By acoustically isolating the two stereo channels, each ear hears only the correct stereo channel. The left ear hears left channel, and the right ear hears right channel. Recordings literally come alive in your listening room. Musical images are reproduced with clarity and pinpoint accuracy. You are immersed in an awe-inspiring three-dimensional sound stage that extends from wall-to-wall (width), floor to ceiling (height) and extends both in-front and behind the speakers (depth).

Pinnacle ring radiator tweeter

New high resolution

40 plus years of tweeter innovation, design and prototyping has led to the development of the new 1” high definition Pinnacle ring radiator tweeter. Developed by Polk Audio, it delivers ultra-clear, crisp highs without unwanted coloration or distortions.


Polk developed the new Turbine Cone specifically for the Legend series to ensure the natural reproduction of the mid-range, the frequencies our ears are so sensitive to. The Turbine cone combines Polk’s proprietary foam core and the molded Turbine geometry which dramatically increases stiffness and damping, without adding mass, resulting in a smooth, detailed mid-range and effortless bass – hear every detail.


For the ultimate listening experience, the L800 can be used for the front stage of any home theater or as side and rear surrounds. Elevate your sound of your home theater set up with our optional Legend L900 height module (sold separately). This works with today’s new home theater technologies including:  Dolby Atmos, DTS, DTS:X, DTS:X Virtual, IMAX Enhanced and Auro-3D.

True stereo

The only way to understand is to hear it for yourself

Drawing from more than 45 years’ experience in developing loudspeakers, the Legend Series defines the next generation of Polk



Polk believes cabinets should be beautiful but add nothing to the playback. Polk Legend cabinets, braces, and internal enclosures are carefully engineered to minimize unwanted internal standing waves and eliminate unwanted resonances. The result is a cabinet that rigidly holds the transducers while faithfully reproducing recordings.


Your sound is only as good as your source. For your investment in DSD, FLAC or a high-resolution streaming service, the Polk Legend L800 is Hi-Res certified so you can be confident that the speaker will faithfully reproduce your favorite songs. Trust Polk Legend series to bring out all the detail of every track.

Anti-Diffraction Magnetic Grille

Comes with a grille to cover the front baffle and a second grille for the top to cover the optional height module when installed. Computer modeled for a precision fit and to minimize sonic interference. The acoustically inert magnetic grilles offer a clean aesthetic without sacrificing sound.

Large Dual 5-Way Binding Posts

Perfect for easy setup, they ensure the most direct, efficient, and loss-less connection possible. Dual binding posts support both bi-wire and bi-amping.
