Get in the action

Whether watching the Super Bowl, the latest blockbuster action movie or even playing your favorite video game, the Polk Legend L400 speaker will put you in the action. Don’t underestimate the most important speaker in your home theater system; go big and make every seat the "sweet spot."

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. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot” and while the critically damped rear-chamber helps to defeat any 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.

New 4" turbine cone mid-range driver

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.

Better bass by design!

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; Polk Enhanced Power Port produces less port noise and more powerful clean bass than traditionally ported loudspeakers. Polk L400 center channel features two 6 ½ inch mid-woofers that extend the lower midrange and bass response of your center channel. From dialogue to explosions, the Polk L400 center channel is full-range to ensure that all center channel content is locked to your screen.

Anti-diffraction magnetic grille

Computer modeled for a precision fit and to minimizes sonic interference. The acoustically inert magnetic grille offer a clean aesthetic without sacrificing sound.

Multi-channel music sounds amazing with the L400. Your sound is only as good as your source, and with High-Resolution certification, the Polk Legend L400 delivers clear and detailed high-end response.

Cabinets built for better performance

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.
