True Performance

Powerful, High-Resolution Sound

The highest performing loudspeaker in the Monitor XT line, the MXT70 maximizes your enjoyment of music, movies, TV and gaming through powerful, high-resolution sound with crystal clear highs and deep, effortless bass. Hi-Res certified, Dolby Atmos and DTS:X compatible, and in a modern, accessibly priced design, Monitor XT70 fulfills the Polk promise of great sound for all.


Certified Hi-Res Audio Performance

Monitor XT70’s Terylene dome tweeters enable playback beyond the range of human hearing—up to 40kHz—ensuring an airy, clear, high-end energy and spaciousness that you’ll not only hear but feel. MXT70 is perfect for enjoying high resolution movies, gaming or the latest hi-res streaming services like Apple Music, Tidal, Amazon Music HD, Qobuz and Spotify HiFi.

Surprisingly Effortless Bass

Polk has always been known for speakers that produce effortless bass, the MXT70 is no exception. Two beefy 6.5” high-efficiency, Dynamically Balanced woofers enhanced by dual 8” passive radiators provide a clean, open mid-range and punchy, responsive bass, with low distortion—making voices and instruments clearly heard and movie soundtracks and music filled with impact.

Built for Pure Listening

Monitor XT70 was made for the enjoyment of pure sound: Dual nickel-plated binding posts guarantee a direct, lossless connection and provide the ability to bi-amp the speakers; low-resonance, critically braced MDF cabinets isolate the sound of the woofer and tweeter without adding unwanted resonances; and their removable, precision-fit grilles minimize sonic interference.

Dolby Atmos & DTS:X Compatible

Compatible with the latest Dolby Atmos and DTS:X surround sound enabled AV receivers and 4- & 8-ohm amplifiers, Monitor XT does not require specialized equipment to deliver great sound. Combine the MXT90 height module with the MXT70 to experience new dimensions of 3D sound.
