Maximize Your Enjoyment

More Bass for Your Home Theater and Music

Monitor XT12 provides Polk’s loud, low, effortless bass so you can enjoy movies, music and gaming with more impact and excitement. 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.

High resolution sound, effortless bass

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 100W Class A/B amplifier delivers bass as low as 24Hz, adding more punch and impact to your favorite 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, seamlessly to your home theater

Monitor X12 features a consistently variable crossover, polarity and volume control to blend the massive bass it provides, seamlessly with your system. In addition, MXT12 offers line level, LFE, and nickel plated binding post inputs, ensuring compatibility with your receiver. Plus, the MXT12 is perfect for the modern trend of integrating two subs into your home theater, for 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 theater or music listening set up. Matched components provide a unified sound field with seamless speaker-to-speaker blending for truly immersive listening experiences.

Rated 5 out of 5 by from Makes all the difference Had all the 5, but not the 1 - tried a friend’s 10” but wasn’t enough, the XT12 hits perfectly and integrated smoothly with amplifier.

I Have a Yamaha AV Receiver RX-V771 (7.2), with pair of Tsi200 bookshelf speakers. Will this sub pair with this equipment/Speakers?

Asked by: TonyRead
Yes, the Polk Audio XT12 powered subwoofer will pair nicely with your system. When connecting the XT12 to your receiver, use an RCA connection from the receiver's Subwoofer 1 output to the XT12 subwoofers L/LFE input.

I have just unboxed my polk monitor xt12 and have a subwoofer cable. what do I need to do to connect to my denon ave s970-h ? the instructions talk about a y adapter and I am confused

Asked by: shawnhome123
Hello, and thank you for your purchase. The Y adapter is an optional accessory and unnecessary when connecting to the Denon AVR-S970H. Using an RCA subwoofer cable, connect one end to the Denon Subwoofer 1 output and connect the other end to the Line in L/LFE input on the Polk Audio XT12 subwoofer. Set the phase to 0, Low Pass to Max, and Volume to 12 o'clock (50% volume). I recommend using the Auto calibration setup within the receiver called Audyssey. If further assistance is required, please get in touch with our support team by visiting https://www.polkaudio.com/en-us/contact-us.html

To connect an old school receiver without sub out is it better to route speaker wires first to xt12 then out of sub to main passive speakers or utilize combined speaker A and B option on receiver by running speaker wire to mains on "A" and sub on "B"?

Asked by: MOJOWORKIN
Hello, Both configurations will work well, but I suggest favoring Speaker A feeding the front left and right speakers, and Speaker B feeding the XT12 sub-woofer for the best performance.
