Polk MM651

The MM651 is a 6 1/2-inch coax speaker designed to fit in a variety of applications. As a result of 3 years of Polk research and development, the new MM series have been designed to offer unparalleled sound quality with exceptional fit to meet virtually any application. Borrowing technology from our flagship SR Series, the MM Series offers exceptional value for the price. Through the use of high-tech composite baskets, powerful neodymium motor structures using oversized voice coils, and state-of-the-art woven glass composite cones, we offer high-end audio performance normally found only in the most expensive loudspeaker systems.
