Designed to provide exceptional sound quality in music, movies, and gaming, the Monitor XT70 2-Way Floorstanding Speaker from Polk Audio is both Hi-Res Audio and Dolby Atmos certified, and compatible with DTS:X, which pair perfectly with the optional MXT90 height modules for a more complete surround experience. Used alone and connected to your A/V system, the XT70 is made to fill your room with crystal clear highs and deep resonating bass, resulting in bombastic movie soundtracks with dialogue you can clearly hear, as well as music with instruments that can be distinctly heard in the mix. All of this is possible with a pair of 6.5″ bilaminate Dynamic Balance woofers supported by dual 8″ passive radiators, and a single 1″ Terylene dome tweeter.
