Easily integrated into any home theater or music listening environment, and featuring new woofer, amplifier, and cabinet designs—the affordably priced MXT12 fulfills the Polk promise of great sound for all.

We Make Loud and Low Seem Effortless

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 Class A/B amplifier delivers bass as low as 24Hz, adding more punch and impact to your favourite music, movies and video games.

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 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.

Add massive bass to your home theater

Monitor X12 features a consistently variable crossover, polarity and volume control to blend the massive bass it provides with your system. Line level, LFE, and nickel plated binding post inputs, ensure compatibility with your receiver. Plus, MXT12 is perfect for integrating two subs into your home theater, for even more bass, while smoothing out the low frequencies throughout the room.
