Polk/MOMO Championship Performance car audio speakers are engineered 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.

The ultra-stiff Dynamic Balance Cone Polk/MOMO Subwoofers womps out massive bass. Its Dish Cone design is mechanically supported by a unique Vented Cone Coupler. This support increases the sub´s axial rigidity. (It´s like "Viagra for your subwoofer"!) Even with huge max power ratings, these subs are optimized for small enclosures, so they fit where you want your bass.

MM2104 Technologies and Features:

• Marine Certified Polk/MOMO 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/MOMO speakers in their award-winning Nautiques ski and wakeboarding boats. Professional wakeboarder Brian Francis choose Polk/MOMO speakers woofers and amps for his MasterCraft boat and Chevy Avalanche truck for maximum entertainment and excitement on the road and wave.
• Ultra-stiff Metalized Polypropylene Dynamic Balance Cone for massive bass.
• Dish Cone design is supported by a Vented Cone Coupler, increasing axial rigidity "like Viagra for your subwoofer!"
• State-of-the-art laser-based Klippel measurement technology perfectly centers the subwoofer´s voice coil in the magnetic field, improving X-max and BL linearity, and the sub´s micro and macro dynamics, for deep, precise, stomach-shaking and spine-wrenching bass.
• Optimized for high performance in small sealed enclosures but versatile enough to pound hard even in bandpass and vented enclosures ¾ Flat, deep bass with great extension as only Polk/MOMO can do it.
• Built tough and backed by one of the best warranty in the car audio world: Three years parts and labor.
• Triple vented for maximum airflow, high dissipation and high power handling: Vented Coil/Cone Coupler, Vented Spider Platform and Vented Pole Piece all allow cooling air to freely flow over the heat-generating components and better harness all the watts your amp can dish out.
• Durable, airtight Rubber Surround for a long life of extended linear motion, optimized to achieve the longest throw possible for the cone: "Big cone, big throw!"
• Huge, fire-retardant flat NOMEX® Spider allows extended linear motion while providing highly reliable mechanical and thermal stability.
• Acoustically inert Stamped Steel Basket with massive, rock-solid non-flexing magnet and motor assembly with removable Rubber Magnet Boot for more damping and deeper install flexibility (reduces product depth by 1/4-inch).
• Anti-Resonance Trim Gasket for tight fit with G Series Grilles, removable for over 1/4² of installation flexibility.
• Heat shrink rubber coated tinsel leads with strain relief terminal connections to take the punishment of long excursion bass.
• Professional Grade Nickel Plated Locking Push Terminals for secure connections; big holes accept nice fat wire, big as 12 gauge!
• Optional MOMO Design "Quasar II" rim-style Grille available separately at your authorized Polk Audio AutoSound dealer.

NOTE: The MM2104 does not replace the MM104. The MM104 offers a cast aluminum basket for "rear-end-out" installations and higher power handling than the MM2104, at a higher cost.
