Polk Audio Legend Series Flagship Loudspeakers (2019)

The Best Speakers Polk Has To Offer

Polk Audio just started shipping a new line of flagship loudspeakers called the Legend Series. There are six speakers in total including two bookshelf speakers (L100 or L200), two floor standers (L600 or L800), the L400 center speaker and the L900 height speaker for Dolby Atmos. Pricing starts at $1,200 to $6,000 per pair to own the most sophisticated and intensively engineered loudspeakers Polk Audio has ever introduced.

“The Legend Series is the culmination of decades’ worth of acoustic engineering and loudspeaker development. Whether placed in a traditional two-channel orientation or home theater system, the new flagship series offers incredible imaging, perfectly balanced mids and deep lows,” said Michael Greco, senior director of global brand management at Polk Audio.

L800 Tower

The behemoth of the Legend Series is the L800 “True Stereo” floorstanding speaker featuring next generation Stereo Dimensional Array (SDA-PRO) technology. It is the first SDA speaker introduced in over 20 years and the only speakers in the world to maintain full stereo separation from the source to the listener’s ears. Polk claims the result is the most lifelike imaging, smooth spectral response and deep, tight bass normally found in speakers several times the cost.

Polk Audio Legend Series L800 SDA Tower Speaker — L800

The Polk Legend series’ L800 tower speaker employs the latest generation of Polk Audio’s celebrated SDA technology, which Matthew Polk invented and debuted in the early 1980’s. The technology is a fundamental shift in loudspeaker design and solidified Polk Audio’s place in audio history. The SDA design minimizes an audio phenomenon known as interaural crosstalk (IAC), which is found in all conventional speakers. Interaural crosstalk is natural distortion found in passive stereo loudspeakers resulting from speakers’ channels crossing before they reach the listener’s ears. SDA technology acoustically isolates the two stereo channels and cancels out IAC to deliver a true stereo listening experience, creating a deep, three-dimensional soundstage that faithfully reproduces the recording.

Reinventing Speaker Design

The new Legend L800 loudspeaker offers a freshly patented SDA-PRO technology, which is the latest evolution of Polk Audio’s SDA design. The new design employs a special “Head Shadow” filter in the dimensional array, which is built to more exactly match—and therefore cancel out—IAC. An additional patent was granted for the L800’s uniquely designed 15-degree angled baffles. This design angles the transducers more precisely toward the listener, which removes any loss of high frequency extension and the need to “toe-in” the loudspeakers.

“From the beginning we wanted to make loudspeakers that virtually transform the listening space into the performance space, creating an intimate, immersive and welcoming experience between the listener and the performer,” said Stu Lumsden, Vice President, Engineering and Quality, Sound United. “When we originally developed SDA in 1982, our goal was the most lifelike imaging you ever heard. We called it True Stereo because we were the first speaker manufacturer to maintain stereo separation all the way from the source to the ears, and that is still true today. After more than forty years developing speakers at Polk Audio, I’m confident the Legend Series are truly exceptional for listeners of all levels. Everyone from discerning audiophiles to casual enthusiasts will immediately hear the difference.”

L600 Tower Speaker

The L600 floor standing speakers ($4000/pr) feature the newly designed high resolution 1” Pinnacle tweeter, 5.25” Turbine Cone mid-range, dual 7” woofers and Enhanced Power Port.

L100 or L200 Bookshelf Speaker

Polk Audio Legend Series L100 Bookshelf Speaker — L100

The L100 bookshelf speaker has a 1” tweeter and a 5.25” woofer. The L200 is slightly larger with a 6.5″ woofer. Both include custom designed parts including a Pinnacle ring radiator tweeter, Turbine cone and enhanced Power Port.

L900 Height Speaker

Polk Audio Legend Series L900 Dolby Atmos Height Elevation Speaker — L900 Height / Elevation Speakers

The Legend L900 Height Speaker Module is designed to deliver the 3D audio found in Dolby Atmos, Dolby Atmos height Virtualization, DTS, DTS:X, DTS Virtual:X, and IMAX enhanced soundtracks. It seamlessly integrates into the L600 and L800 floorstanding loudspeakers via flush mounting system instead of a topper. That configurations offers a cleaner look and reduces diffraction effects from the baffle for a smoother frequency and time response to the listener.

L400 Center Speaker

The L400 is a full range center channel speaker featuring the newly designed 1” Pinnacle tweeter, 4” Turbine Cone mid and dual 6 ½” woofers with Enhanced Power Port.

Legend Series Features

Pinnacle Ring Radiator Tweeters: Decades of tweeter innovation, design and prototyping led to the development of the new 1-inch high definition Pinnacle ring radiator tweeter. Developed by Polk Audio, it delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide, which dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot,” while the critically damped rear-chamber helps defeat unwanted resonances. Hi-Res certified, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multi-channel 3D audio found in music, movies, sports, and video games soundtracks.
Turbine Cones: Polk developed the new Turbine cone specifically for the Legend series to ensure the natural reproduction of the mid-range—the frequency range human ears are most sensitive towards. 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.
Enhanced Power Port Design: Extending the low-end, the upgraded Power Port technology produces less port noise and more bass than traditionally ported loudspeakers. Polk Audio improved the traditional Power Port design by smoothing out the port flare, which offers a smoother transition into the listening area and adds multiple dBs of bass response.
Advanced Cabinet Construction: The intensively engineered cabinet designs add rigid bracing and structure to control vibration and eliminate unwanted audible distortion.
