High performance. Anywhere you want it.

The M3 combines superior sound in a small package of exceptional design. One of this speaker's advantages is the installation option allowing for convenient placement anywhere in your home. The tradition of open, clear, and boxless sound that has made Polk Audio loudspeakers popular all over the world is evident from the first listening of your new M3.

Particular attention has been paid to 10 high efficiency for use with a variety of amplifier sources, 2) excellent transient response, 3) precise imaging for an exciting musical experience, and 4) smooth, accurate frequency response to insure that you hear all the music.

The M3 can be used in a multitude of applications due to its stand/mounting bracket. This integration allows the M3 to be used not only as a traditional bookshelf speaker, either horizontally or vertically, but also as a wall-mounted speaker in various configurations. As you read further you will see that the M3 is ideal as an auxiliary pair of loudspeakers in many rooms of a multi-room sound system. It also performs as a surround sound speaker in a sophisticated audio/video system.
