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 without adding unwanted resonances; and their removable, precision-fit grilles minimize sonic interference.

Polk-Patented Quality and Five-Year Warranty

Designed and engineered by the same team that created Polk Legend and Reserve in our Acoustics Research and Development center outside of Baltimore, MD. Polk uses a patented Dynamic Balance Array process to pinpoint and eliminate electroacoustic 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 five-year limited warranty to ensure years of listening enjoyment.
