LEGEND L400 // Center Channel Speaker

The 'Heart' of any home theater, the Polk Legend L400 center speaker was designed to go big and put you right in the middle of the action. Whether watching the Super Bowl, the latest blockbuster, or even playing your favorite video game, the L400 center speaker will put you in the middle of the action. Don’t underestimate the most important speaker in your home theater system— feel, hear, and understand every word.

Over 40 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. This ensures a broad “sweet spot” while the critically damped rear-chamber helps to defeat any unwanted resonances.

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 to dramatically increases stiffness and damping without adding mass. The result is a smooth, detailed mid-range and effortless bass.

Traditional bass ports make noise (chuff) and mask the low frequency bass notes you want to hear. The new enhanced Power Port® design smoothly transitions air flow from the speaker into your listening area for louder, cleaner bass while minimizing turbulence, distortion, and port noise. Polk refined their current Power Port technology specifically for the Legend series by fine-tuning the geometry of the port flare. Hear and feel the difference with less port noise and more powerful bass than traditionally ported loudspeakers.
