## Description

The Polk Monitor XT12 powered subwoofer is outfitted with a 12” Dynamic Balanced Woofer and 100 W peak Class A/B amplification; delivering loud, low, effortless bass. Audiophiles, homeowners, or anyone who is a gamer can enjoy movies, music, and gaming; with more impact, amazing speed, and control even at 24 Hz.

The home audio subwoofers have a rigid, low-resonance cabinet that keeps each note clean; while the driver moves ample air for truly deep bass. Easily integrated into any home theater or music listening environment. Featuring new woofer, amplifier, and cabinet designs—the MXT12 12 inch subwoofers fulfill the Polk promise of great sound for all. Add another, same-model subwoofer to your setup to improve realism, smooth peaks and dips; deliver even bass for every movie and song.

Review: Value - A great Subwoofer, regardless of cost! This is a very good subwoofer, solidly build at a very reasonable price, ESPECIALLY IF YOU CAN GET ON SALE. It has all the inputs you need, including speaker level inputs. Arguably this is the best way to hook up your sub, because it gets the same input as the main speakers and then low pass filters it. I have tried this sub with a 35 W rms/ch amplifier and relatively small hi-fi speakers and a 100 W rms/ch amplifier with large floor standing hi-fi speakers. In both cases it really boosts the low frequencies making the sound full, deep and well separated. For starters, set the volume level to just under half and the low pass filter to 80 Hz, listen to a variety of music genres and adjust to your liking. The sound output is deep, musically pleasing and you can feel the low bass notes in your gut!
