At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Enclosure Compatibility
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.
