Polk Precision

Built for Pure Listening

All Monitor XT models are made for the enjoyment of pure sound: Their nickel-plated binding posts guarantee a direct, lossless connection; 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.


Five Decades of Speaker Engineering

Monitor XT series is the culmination of five decades of Polk’s premium loudspeaker engineering and were designed at our original Acoustic Research and Development facility in Owings Mills, Maryland.

Our goal since our founding in 1972 has been to build great loudspeakers that transport you to the scene of the recorded performance. Later with the advent of home theaters, to make you feel that you’re in the center of the action. We’ve achieved this by constant innovation and by leaving nothing to chance. The result of this 50-year engineering heritage is best-in-class loudspeakers backed by numerous awards, patents, and fans like you.

All Polk loudspeakers are built to last. We rely on a patented Dynamic Balance Array process to pinpoint and eliminate electro-acoustic and mechanical issues before they become a part of the finished speaker. We’re so confident of this process, that we back the Monitor XT Series with a limited 5-year warranty to ensure years of listening pleasure.

With Polk Monitor XT loudspeakers, you’ll maximize your enjoyment of movies, music and gaming with high-resolution, room-filling sound with effortless bass. Hi-Res Audio Certified, accessibly priced, and built to exceed our patented, quality-testing process, the Monitor XT series fulfills the Polk promise of great sound for all.
