Polk Audio MM455 Car Audio System

A small package of beautiful styling and tremendous power, the MM455 5.25" driver is housed in its exclusive cast aluminum, diamond-polished MOMO Arrow basket for extreme durability.

It's heavy metal, built for speed and sound, and it fits right in your car.

* Polk/MOMO is built tough and backed by a three year Parts and Labor warranty, the best warranty in the car speaker world.
* The super strong polymer/mica composite cones, airtight Elastomer rubber surrounds and flat, bulletproof Aramid Fiber spiders deliver rock solid mid-bass response and lifelike midrange detail.
* The "billet-style" grille minimizes obstructions for an even more "open" sound; a sound you won't find in any other little speaker, especially one that looks this cool.
* The component system features the MM400 Dome Tweeter, and the beautiful new Polk Audio/MOMO Crossover.

You can plainly see (and hear) the benefits of the new MM System Crossover: Mylar capacitor/air core inductor tweeter components for better transparency. Polypropylene capacitor/laminated steel midrange components handle high current without saturation for more dynamic impact. 12dB/octave slope with midrange bypass, 3-position tweeter attenuation for the ultimate in flexibility. Gold signal traces and gold-plated terminals for exact connections.

Polk Audio/MOMO High Performance Car Audio Speakers are built by Polk Audio with ultra high-tech materials for competition-level performance and durability. They're styled exclusively by MOMO, the world's preeminent designer of racing accessories, to look as good as they sound. And for motor sports enthusiasts the world over, a MOMO product is a charismatic symbol of the finest quality.

When you consider your car an extension of your personality, Polk Audio/MOMO High Performance Car Audio is the perfect synthesis of technology and design.
