Patented X-Port

Traditional ported speaker designs increase low- frequency performance, but often mask midrange details due to port resonances. Polk's proprietary X-Port uses specially tuned eigentone filters to cancel out unwanted resonances. With X-Port you get the best of both worlds: tight, distortion-free bass and a superbly detailed midrange.

Form and Function

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.

Hi-Res Audio Certified

Your sound is only as good as your source. With Hi-Res Audio certification, the Polk Reserve R100 delivers clear and detailed high-frequency response. Female vocals are particularly smooth, with exceptional clarity and without coloration. Plus, a minimum support of 40kHz perfectly reproduces the latest Hi-Res Audio files with improved audio extension.
