Polk Reserve R400 – Center Channel Speaker

Pinnacle Ring Radiator Tweeter
Developed by Polk Audio, the new high definition Pinnacle Ring Radiator™ Tweeter delivers ultra-clear, crisp highs, without unwanted distortions. 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
Polk's Reserve series integrates X-Port, 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.
