Description

The center channel is the most important speaker in a home theatre set up and the R400 delivers crisp and easy to understand dialogue for all your favourite movies and shows. With dual 6.5” Turbine cones and 1” Pinnacle tweeter, the R400 offers serious home entertainment impact.

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 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 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.

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.

Polk Newly Patented X-Port (ETF)
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.
