• 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.

• 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.
