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.

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.

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.

X-Port
Reserve R400 features two X-Ports, featuring a set of closed-pipe resonators, called Eigentone filters that are tuned to absorb unwanted port and cabinet resonances, providing you pure, unadulterated, crystal clear sound and more bass output.

Exceptional Cabinetry
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.
