Customer Rating:
The MM6501UM is a dedicated component system for your watercraft needs. By using advanced materials, we have the best of both worlds: reliability and great sound quality. Designed and styled specifically for use in the marine environment, this isn't just a car system labeled for use on a boat. Use it in overhead speaker-cans or installed on your boat, it works great for both!
- Stainless Steel Heavy Duty Input Terminals and mounting hardware will not corrode or tarnish.
- Sealed Crossover Assembly is built Into Back of Magnet means there's no need to find room to hide an extra box.
- Passes The Most Rigorous 600 Hours of Salt Fog and UV Testing (ASTM International B117-03 Standard Practice for Operating Salt Spray (Fog) Apparatus and D4329-99 Standard
- Dynamic Balance® Driver Technology for pure, distortion free sound.
- Neodymium is a rare earth material we use in all MM driver magnets, excluding 461p, that are about 1/10 the weight of a comparable ceramic magnet and much more powerful.
- Carbon Composite Basket based on the spokes of a wheel is lightweight and will not flex.
- Woven Glass Composite Cones feature tremendous stiffness-to mass ratio and are weather resistant. Lower mass means faster transients and finer detail.
- Klippel Optimized Components 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 Audio speakers in their award-winning Nautiques ski and wakeboarding boats.
- Large-Diameter Voice Coil (30mm) in drivers increases reliability and power handling capacity.
MM Series Features
Unlike stamped steel designs found at the same price, Polk's MM Series carbon composite baskets are dramatically more rigid and robust, which results in lower distortion and countless years of reliability.
Carbon Composite Basket
Based on the spokes of a wheel, the MM Series basket is lightweight, will not flex during peaks and looks great! Don’t be afraid to show off the back of your speaker.
Proven high-performance features. And we can prove it.
Less Power, More Output
High Efficiency Design means less amplifier power is needed for more audio output. While a separate amp is recommended on full range models for the ultimate in performance, MM Loudspeakers will sound wonderful when driven by aftermarket head units or factory installed electronics.
Slim & Light Weight
When you first pick up a MM series speaker, you may wonder why it's so light or why the magnet is so small. The answer: advanced technology. First the MM Series uses a Neodymium Magnet Structure This premium material allows us to replace the traditional bulky ceramic magnet with one more compact and much lighter. The benefit is a physically slimmer speaker, which means it can fit into more applications. In addition, we can increase the venting of the speaker to keep it cool when playing at high volumes.
Legendary Polk sound. Legendary Polk reliability.
Polymer woofer cones and Butyl rubber surrounds provide superb reliability in the harsh confines of automotive environments for year after year of great Polk performance. All models feature oversized voice coils and Polyimide/fiberglass formers for reliability and greater power handling: 30mm for the 61/2" and 5x7 speakers; 38mm for the 6x9 and 25mm for the 5 1/4" drivers. In addition to being extremely rigid, our carbon composite basket designs enabled us to increase speaker venting to keep things cool, even when you crank it way up.
Klippel Optimized Components
In order for a driver to reproduce complex sounds accurately, the voice coil and cone must move exactly the same distance and manner in both directions of travel. The Klippel Distortion Analyzer--a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, enables us to optimize the motor structure, voice coil alignment and suspension to yield the best possible performance.
