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.
Power and Clarity
As we get older, we learn what better looks like, feels like, tastes like, and even drives like. Inheriting best-in-class technologies from our flagship Legend series of loudspeakers, the Polk Reserve series helps teach you what better sounds like.
Crystal Clear Vocals for 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.
Sit right everywhere
Pinnacle Ring Radiator Tweeter
The Pinnacle Ring Radiator Tweeter’s distinctive pointed shape guides the dispersion of high frequency sounds around a room. This innovation widens the sweet spot and allows you freedom to enjoy your music and movies wherever you choose to sit.
Strength in motion
Turbine Cone Woofer
Our pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a breathtaking level of detail in your music and movies.
Purity of Sound
Polk's proprietary X-Port eliminates unwanted noise created as air moves in and out of the speaker cabinet port at high-speeds. This ensures a rich and detailed listening experience with tight distortion-free bass and a clean midrange.
Form and function
Reserve’s sleek cabinetry hides a world of audio innovation. Cabinets are carefully cross-braced to best eliminate unwanted interior resonances. Rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage.
