The Centrepiece Of Your System Clear, Focused Hi-Res Sound

Monitor XT30 maximises your enjoyment of movies, TV and gaming with crystal clear, focused dialogue, effortless bass, and dynamic, high-resolution sound. Hi-Res Audio Certified, Dolby Atmos and DTS:X compatible, and in a modern, affordable design, the XT30 fulfils the Polk promise of great sound for all.

Purity Of Sound 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, multi-channel concert videos, and spatial audio mixed for Apple Music, Dolby Atmos, or DTS:X.

Making An Impact Surprisingly Effortless Bass

Polk has always been known for speakers that produce effortless bass that’s surprising for their size. The XT30 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.

No Special Gear Required Dolby Atmos Certified & 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 specialised equipment to deliver great sound.

Designed Better 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 minimise sonic interference.


Introducing The Monitor XT Series

When the original Polk Monitor Series debuted in the 1970's, it set a new standard for loudspeaker performance and value—with clear, accurate response, powerful bass, and lifelike imaging at a price that made great sound available to everyone.

Monitor XT Series continues this tradition, leveraging Polk’s 50 years of acoustic innovation. Refined transducers work with precisely tuned crossovers to reproduce your audio in exquisite detail. And they’re housed in rigid, strategically braced cabinets for purer, more authentic reproduction.

When you experience Monitor XT’s power, warmth, and clarity, you’ll get lost in the action of your favourite movies and games, and you’ll fall in love with your favourite music all over again, whether you’re spinning vinyl or streaming playlists. Hi-Res Audio and Dolby Atmos certified, accessibly priced, and built to last, the Monitor XT Series truly fulfils the Polk promise of Great Sound for All.
