Polk has always had a reputation for speakers that produce deep, powerful, and effortless bass, and the MXT12 is no exception. A large, 12” Dynamic Balance driver in a ported enclosure, powered by a clean and hyper-efficient 100W Class A/B amplifier, delivers bass as low as 24Hz, adding more impact and power to your favorite music, movies, and video games.

Engineered to withstand the demand for bass. When you want bass that is both loud and low, your subwoofer needs more than just an excellent driver and powerful amplifier to seem effortless. The Monitor XT12 is housed in a critically reinforced MDF enclosure with a removable, precisely fitted grille to isolate the speaker's sound while minimizing unwanted reflections and acoustic interference.

Add mammoth bass seamlessly to your home theater. The Monitor X12 features continuously variable crossover, polarity, and volume control to blend the mammoth bass it provides seamlessly with your system. Additionally, the MXT12 offers line-level, LFE, and nickel-plated input terminals, ensuring compatibility with your receiver. The MXT12 is also ideal for the modern trend of integrating dual subwoofers in your home theater for even more bass while smoothing out low frequencies throughout the room.
