R400 Center Channel Speaker

The R400 offers unrivalled power and clarity from a center channel speaker. The addition of two 6.5” turbine cone woofers and Polk’s unique X-Port technology means it delivers enormous yet balanced sound, ideal for the ultimate home theater system.

 Crisp dialogue and dynamic sound right in your living room

The Polk Reserve R400 center channel speaker features dual 6.5” Turbine cones and a 1” Pinnacle tweeter. This flagship transducer array delivers the clearest, most intelligible vocals for your favorite movies, shows, games and more. The newly patented X-Port eliminates cabinet resonance for distraction-free enjoyment.

 Cabinets Built for Better Performance

Polk believes cabinets should be beautiful and add nothing to the playback. Polk Reserve 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 transducer array while it faithfully reproduces recordings.

 Polk’s Newly Patented X Port (ETF Port)

Polk’s newly patented X-Port incorporates an Eigentone Filter (ETF) offering distortion-free, effortless bass. Consisting of a set of closed-pipe absorbers that are specifically tuned to catch and eliminate traditional speaker distortions. X-Port ensures that the upper bass and mid-range are free of port and cabinet resonances for smooth, detailed audio.

 High Definition Pinnacle Ring Radiator Tweeter

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 by Polk Audio, it delivers ultraclear, 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 rearchamber helps 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 movies, sports, and video game soundtracks.

 Crystal Clear Vocals For Your Home Theater

The center channel is the most important speaker in any home theater setup. The Reserve R400 uses Polk’s latest flagship transducer array to deliver clear, crisp, intelligible dialogue no matter where you sit.

 6.5” Turbine Cone

Polk developed the Turbine cone specifically for our flagship products to ensure the natural reproduction of the mid-range, to which human ears are particularly sensitive. The Turbine cone combines Polk’s proprietary foam core and molded Turbine geometry which dramatically increases stiffness and damping, without adding mass. You will hear every detail and experience a smooth, detailed mid-range and effortless bass.
