The Polk Reserve R400 center channel speaker offers unrivalled power and clarity from a center channel speaker. 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. 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. The Pinnacle Ring Radiator Tweeter’s distinctive pointed shape guides the dispersion of high frequency sounds around the room. This innovation widens the sweet spot and allows you freedom to enjoy your music and movies wherever you choose to sit. The pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution and a breathtaking level of detail. 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. Reserve’s sleek cabinetry is carefully cross-braced to eliminate unwanted interior resonances. Rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage.
