Polk L400 Premium Center Channel Speaker

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.

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.

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.
