Add More Impact

We Make Loud and Low SeemEffortless

Polk has always been known for speakers that produce deep, powerful effortless bass, and the MXT12 is no exception. A big, 12” Dynamically Balanced woofer in a ported cabinet, powered by a clean and ultra-efficient 100W Class A/B amplifier delivers bass as low as 24Hz, adding more punch and impact to your favorite music, movies and video games.

Heavy Duty Housing

Built ToWithstand TheRumble

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 XT12 is housed in a critically braced MDF cabinet with a removable, precision-fit grille to isolate the sound of the woofer while minimizing unwanted resonances and sonic interference.
