Designed to Perform
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.
- Space age materials reduce weight of components while offering rock solid reliability, advanced looks and ultra-high performance.
- Neodymium magnets a rare earth metal offering exceptional strength to performance ratio, found only in the most exotic speakers, saves tremendous weight. Don't let the sound system weigh your vehicle down. Since the magnet is smaller, the speaker can fit into more applications.
- Carbon composite basket based on the spokes of a wheel is lightweight, will not flex during peaks and looks great! Don't be afraid to show off the back of your speaker.
- Woven glass composite cones feature tremendous stiffness-to mass ratio. Lower mass means faster transients and finer detail.
- Klippel optimized components using a state-of-the-art Klippel distortion analyzer, Polk engineers were able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance, even at extreme listening levels.
- Marine Certified Polk MM Series speakers are built tough to withstand the toughest environments so they are perfect for use in boats of all types. That's why Correct Craft offers Polk speakers in their award-winning Nautiques ski and wakeboarding boats.
- Large-diameter voice coils (30mm) in drivers increase reliability and power handling capacity.
- Swivel mount tweeters allow precise aiming of sound.
- Stylish grille is included.
