NEW HIGH RESOLUTION 

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 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” 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

ENHANCED POWERPORT

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” 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

LARGE DUAL 5-WAY BINDING POSTS

Perfect for easy setup, dual binding posts ensure the most direct, efficient, and loss-less connection possible while supporting both bi-wire and bi-amping.

HIGH-RESOLUTION CERTIFIED

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.

REAL WOOD CABINETS

From the first hand-made cabinets built in 1972 to today’s new flagship speaker series, Polk has been designing wooden cabinets with real wood for over 45 years. Inspired by our heritage, Legend carries forward that tradition of classic design of a high-performance loudspeaker. Available in two real wood veneer finishes: brown Walnut and black Ash.
