Dynamic Balance Woofer - Take Entertainment To New Depths

A 10” long-throw, high-excursion woofer produces the deep, effortless bass that Polk is famous for, all the way down to 24Hz. You won’t just hear it—you’ll feel it in your bones.


Add More Impact We Make Loud And Low Seem Effortless

Polk has always been known for speakers that produce deep, powerful, effortless bass, and the XT10 is no exception. The compact but powerful 10” Dynamically Balanced woofer is housed in a ported cabinet and powered by a robust, 100-watt peak, Class D amplifier,  delivering consistently pristine sound, whether you’re dialling things down or turning it up to 11.


Heavy-Duty Housing Built To Withstand The Rumble

When you want bass this loud and this low, your subwoofer needs more than a great woofer and powerful amplifier to make it seem effortless. Monitor XT10 is housed in a critically braced cabinet with a down-firing port that minimizes resonances and sonic interference, for defined, room-filling low end.


Add Massive Bass, Seamlessly To Your Home Theatre

Monitor X10 features a consistently variable crossover, low-pass filter, polarity and volume control to let you fine-tune bass response in your system, whether you prefer subtle low-end enhancement or room-shaking rumble. Plug in and power up in seconds with versatile line-level/LFE inputs that are compatible with most audio receivers.


Iconic Sound For Modern Entertainment

Maximize your enjoyment of today’s high-resolution and immersive film, TV, music, and game platforms. A subwoofer doesn’t just enhance bass—it works in tandem with full-range speakers to improve overall system performance and unveil a new dimension in music. The soundstage opens up, imaging is more accurate, and dynamics are deeper than ever. You’ll hear your favourite songs in a whole new way.

Combine the MXT10 with full-range Monitor XT speakers to experience truly multidimensional Dolby Atmos, DTS:X, and Auro 3D sound. MXT10 is timbre-matched to the Monitor XT Series, so you’ll get a seamless, blended sound-field from low to high.

Monitor XT10 is perfect for the modern trend of integrating two or more subwoofers into your home theatre. You’ll get even more bass, while smoothing out the low frequencies throughout the room.

Solid Polk Sound 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 theatre or music-listening set-up. Matched components provide a unified sound field with seamless speaker-to-speaker blending for truly immersive listening experiences.


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.
