Certified Hi-Res Audio Performance

Monitor XT30's Terylene dome tweeter enables 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. Its high-resolution performance is perfect for the enjoyment of sound found in ultra-HD movies, multichannel concert videos, and spatial audio mixed for Apple Music, Dolby Atmos, or DTS:X.

Surprisingly Effortless Bass

Polk has always been known for speakers that produce effortless bass that's surprising for their size. The MXT30 is no exception. Dual 5.25" high-efficiency, dynamically balanced woofers provide a clean, open mid-range and punchy, responsive bass, with low distortion—leaving voices and music clear while filling concerts, movies, and games with impact.

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

Polk Audio Speakers

Consistent Sound Throughout the Series

The Monitor XT Series was designed with quality, timbre-consistent components throughout to enable you to mix and match models to build your dream home theater or music listening setup. Matched components provide a unified sound field with seamless speaker-to-speaker blending for truly immersive listening experiences.
