The R400 delivers unparalleled power and clarity from a center speaker. The addition of two 6.5-inch turbine cone woofers and Polk's unique X-Port technology means it delivers huge but balanced sound, ideal for the ultimate home theater system.
Power and clarity
As we get older, we learn what it looks, feels, tastes and even behaves like. Inheriting best-in-class technologies from our flagship Legend speaker series, the Polk Reserve series helps you learn what the best sound is like.
Crystal-clear voices for the home theater
The center channel is the most important speaker in any home theater setup. The Reserve R400 uses Polk's latest flagship driver array to deliver clear, crisp, intelligible dialogue wherever you sit.
Pinnacle ring radiator tweeter
The distinctive pointed shape of the Pinnacle Ring Radiator Tweeter guides the dispersion of high-frequency sound throughout a room. This innovation expands the sweet spot and gives you the freedom to enjoy your music and movies wherever you choose to sit.
Turbine cone woofer
Our pioneering turbine design offers a significant increase in cone stiffness without increasing mass. This innovation means the woofer can move with greater precision and speed to deliver improved sound resolution, allowing you to enjoy a breathtaking level of detail in your music and movies.
X-Port
Polk's exclusive X-Port eliminates unwanted noise created when air moves in and out of the speaker port at high speeds. This ensures a rich, detailed listening experience with tight, undistorted bass and clean mids.
