The Polk Audio R200 is a large bookshelf speaker designed for high-performance audio, featuring a 6.5-inch Turbine Cone Woofer for powerful bass and a 1-inch Pinnacle Ring Radiator Tweeter for clear, detailed highs. It is Hi-Res Audio certified, compatible with Dolby Atmos and IMAX Enhanced, and includes Polk's X-Port technology to ensure tight, distortion-free bass. The cabinet is cross-braced and has rounded edges to minimize unwanted resonance and diffraction for a wider, more open soundstage.
