Designed to Impress

Designed from the ground up to be ultimate high performance center channel loudspeaker, Polk's Legend L400, with its flagship audio technologies, 3-way design, and beautiful cabinetry, has earned its place as the centerpiece of your home theater. Great sound without compromise.

4" turbine cone

Polk developed the 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.

Enhanced Power Port

With dual Power Ports, the L400, provides full range impact, matched with immaculate nuanced detail—front and center. Our patented Power Port technology smoothly transitions air flow from the speaker into your listening area resulting in louder, cleaner bass and more defined midrange without the turbulence, distortion, and port noise typically found in traditional ported speaker designs.

Pinnacle Ring Radiator Tweeter

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 for the Legend Series, it delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot” while the critically damped rear-chamber helps to defeat any unwanted resonances.

Crisp and Clear

Hi-Res Audio-Certified Performance

Your sound is only as good as your source. With High-Resolution certification, the Polk Legend L400 delivers clear and detailed high-end response. Female vocals are smooth and detailed without coloration. Plus, a minimum support of 40kHz perfectly reproduces the latest high resolution audio files with improved audio extension.
