Often overlooked, the center channel speaker is a vitally important part of your home theater setup.  The L400 center channel speaker features newly created technologies like a 4” Turbine Cone, a 1” Pinnacle tweeter oriented vertically to maximize dispersion, two 6 ½’ woofers and enhanced Power Port which will place you in the center of the action.  Feel, hear and understand every word without compromise.

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” 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 Turbine Cone

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 and effortless bass – hear every detail.

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.

Compliments your Home Theater

Can be used for the front stage of any home theater, as well as side and rear surrounds. Legend Height Module (L900) are only compatible with floorstanding models.

Anti-Diffraction Magnetic Grille

Comes with a grille to cover the front baffle and a second grille for the top to cover the optional height module when installed. Computer modeled for a precision fit and to minimize sonic interference. The acoustically inert magnetic grilles offer a clean aesthetic without sacrificing sound.
