The most important speaker in your Home Theater
The center channel is the most important speaker in a home theater setup, and the R400 speaker delivers clear, easy-to-understand dialogue for all your favorite movies and TV shows. With dual 6.5" Turbine drivers and a 1" Pinnacle tweeter, the R400 packs a punch for home entertainment.

High-resolution Pinnacle Ring Radiator Tweeter
Over 40 years of tweeter innovation, design and prototyping have led to the development of the new Pinnacle 1" High Definition Ring Radiator Tweeter. Developed by Polk Audio, it delivers ultra-bright, clear high frequencies without unwanted coloration or distortion. The Pinnacle Tweeter features a finely tuned waveguide, which dramatically improves the dispersion of high-frequency energy for a wide sweet spot, while the carefully damped rear chamber helps eliminate unwanted resonances. Hi-Res Audio certified, the Pinnacle Tweeter is designed for today's two-channel music and the 3D multi-channel audio found in movies, sports and video game soundtracks.

6.5" Turbine Cone
Polk developed the Turbine cone specifically for our flagship products to ensure natural reproduction of the midrange to which the human ear is particularly sensitive. These Turbine cones combine Polk's proprietary foam construction and molded Turbine geometry that dramatically increase stiffness and damping, without adding mass. You'll hear every detail and experience a smooth, detailed midrange and natural, pleasing low frequencies.

New Polk X-Port Patent (ETF)
Polk’s new patented X-Port features an Eigentone Filter (ETF) that delivers smooth, distortion-free bass. Consisting of a set of closed-tube absorbers that are specifically tuned to capture and eliminate distortion from traditional speaker cabinets, X-Port ensures that the upper bass and midrange are free from port and cabinet resonances, resulting in smooth, detailed audio.

Cabinets built to improve performance
Polk believes that cabinets should look good and add nothing to the reproduction. Polk Reserve cabinets, bracing, and internals are precision engineered to minimize unwanted internal standing waves and eliminate unwanted resonances. The result is a cabinet that rigidly holds the transducer array while faithfully reproducing recordings.
