Ultra Marine Speakers
Kick some serious asphalt.
For you it's all about clutch popping, snap-your-head back performance, obsessive Q-tip detailing and fifteen coats of clear. But in the end, bhp, torque curves and low-profile tires can take you only so far. So your maniacal quest turns to smaller, lighter, stronger, all without sacrificing one foot-pound of performance. That's exactly how we approached our new Mobile Monitor Series: as an all-out run on performance, style and finish that, when it comes to beefing up any car's audio performance, makes the new MM the perfect fit.
The advantages of being lightweight and shallow.
First, we optimized every performance parameter so every MM speaker would work with the latest thinking in automobile design. All models in the MM Series--coaxial, systems and subwoofers--use newly developed carbon composite basket structures. As you might suspect, carbon composite baskets are significantly more rigid and robust than stamped steel baskets therefore way less likely to be a source of distortion; carbon composites also measure their reliability in years.
Instead of the bulky conventional ceramic-ferrite structures normally used, all full-range MM models (except the MM461p) employ incredibly strong and efficient Neodymium magnets. In fact, Neodymium magnets are about a tenth the weight of a comparable ceramic structure. A basket requiring less material and a more compact magnet mean every MM speaker has a smaller overall "envelope" (determined by its widest and deepest points). Another benefit of this smaller envelope is the shallow mounting depth. These "leaner," "meaner" profiles enable MM to fit into virtually any installation, take up less space, and do it with half the weight of most other speakers and those are kind of benefits that pay dividends on your performance bottom line.
Wild and Wet. At home on land or sea.
Marine Certification makes all models suitable for use on watercraft and land vehicles. MM Series speakers are
subjected to a series of grueling real world and accelerated weathering lab tests to see if they could
stand up to harsh marine and automotive environments. We exposed them to hundreds of hours of salt fog,
intense ultraviolet light and extreme temperatures from -40° to 185° F (-40° to 85° C), then gave them
a listen. All MM Series speakers and subwoofers have passed test after test with flying colors, so
you're assured of one consistent performance after another, whether it's on the road or on the water.
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.
