American Power, Italian Finesse
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.
