Our take on the Polk Audio MM2154D

Polk and accessories specialist MOMO have joined together to create the high-performance Polk/MOMO subs. These stylish subs deliver powerful, accurate bass that sets you apart from the pack — both sonically and visually.

The Polk/MOMO MM2154D 15" subwoofer features a polypropylene concave "dish" cone, metalized for maximum rigidity. A huge, high-roll butyl rubber surround controls longer cone excursion for high-impact bass with lower distortion. State-of-the-art laser technology centers the voice coil perfectly in the motor structure's magnetic field for optimized performance.

These high-impact subs feature a triple venting system for maximum air flow, power handling, and reliability. Gaskets on the front and the back of the basket insure an airtight installation. This subwoofer is designed for use in a small, sealed enclosure.

Don't limit yourself to only using these subs in your car — they've passed tough environmental testing that certifies them for marine use as well.

Features

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Marine Certified: Polk/MOMO Series speakers are built to withstand exposure to moisture and UV rays, so they work well in boats and cars.

Metalized Polypropylene Woofer Cone: This woofer features an ultra-stiff metalized polypropylene Dynamic Balance cone for massive bass. Its Dish Cone design is mechanically supported by a unique Vented Cone Coupler. This support increases the sub's axial rigidity.

Rubber Surround: The cone uses a durable, airtight rubber surround for a long life of extended linear motion.

Stamped Steel Basket: The acoustically inert stamped steel basket offers lower distortion.

NOMEX Spider: The huge, fire-retardant flat NOMEX spider allows extended linear motion while providing highly reliable mechanical and thermal stability.

Klippel Measurement Technology: 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 bass.

Triple Vented: The 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.

Rubber Magnet Boot: The removable rubber magnet boot provides additional damping and deeper installation flexibility. With the magnet boot removed, the woofer has the following dimensions:

  • Magnet Diameter: 5.551"
  • Depth as top: 7.056"
  • Depth as bottom: 7.617"

Dual Voice Coils: The MM2154DVC features dual 4-ohm voice coils. When wired together in parallel, the subwoofer will present a 2-ohm load. When wired in series, the subwoofer will present an 8-ohm load. The woofer's voice coils can also be driven by separate amplifier channels.

Terminals: The woofer has professional grade nickel-plated push terminals that will accept bare wire (up to 12-gauge), banana plugs, dual banana plugs, and pin connectors.

Enclosure Compatibility

Recommended Sealed Box Volume: Polk recommends using this woofer in a sealed enclosure with an internal volume of 1.5 cu/ft. It can also work in a vented or bandpass enclosure, however, no recommended enclosure size is given.

The type of bass you get from your component subwoofer doesn't depend on the woofer alone. You'll need a strong, tightly constructed enclosure for optimum subwoofer performance.
