POLK/MOMO: CHAMPIONSHIP PERFORMANCE
Polk/MOMO MM Subwoofers
• Four Single Voice Coil (SVC) Subs:
8" (MM2084), 10" (MM2104), 12" (MM2124) & 15" (MM2154).
• Four Dual Voice Coil (DVC) Component Subs: 8" (MM2084DVC),
10" (MM2104DVC), 12" (MM2124DVC) & 15" (MM2154DVC).
• Ultra-stiff Metallized ABS Dynamic Balance Cone for massive bass.
• Dish Cone design is supported by a Vented Cone Coupler, increasing axial rigidity.
• 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 spinewrenching bass.
• Optimized for high performance in small sealed enclosures but versatile enough to
pound hard even in bandpass and vented enclosures—Flat, deep bass with great
extension as only Polk/MOMO can do it.
• Built tough and backed by the best warranty in the car audio world: Three years
parts and labor.
• 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 stability.
• Acoustically inert Stamped Steel Basket with massive, rock-solid non-flexing
magnet and motor assembly, Anti-Resonance Trim
Gasket and removable Rubber Magnet Boot for more
damping and deeper install flexibility.
• Triple vented for maximum airflow, high heat
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.
• Professional Grade Nickel Plated Locking Push
Terminals for secure connections; big holes accept nice fat wire, big as 12 gauge!
Dual connections on DVC models.
• Optional MOMO Design “Quasar II” rim-style Grille available
separately at your authorized Polk Audio AutoSound dealer, or
at www.shop.polkaudio.com.
Getting Started
Please inspect your loudspeaker(s) carefully. Notify your Polk Audio dealer if you notice any
damage or missing items. Keep the carton and packing material; this will do the best job of
protecting your speaker(s) if they must be transported.

Safe Limits Of Operation
Your Polk Audio Loudspeakers are constructed of the highest quality materials for years of
trouble-free performance. However, damage to loudspeakers can occur when an amplifier,
regardless of its wattage, is made to play at higher listening levels than its power can clearly
produce. This is usually beyond the “12 or 1 o’clock” position on the volume control.
Operation at this level can result in very high levels of audible distortion originating in
the amplifier, which can add a harsh, gritty sound to your listening material. If you hear
distortion—turn it down! Contrary to popular belief, a speaker is more likely to be
damaged by trying to get too much volume from a low-powered amplifier or receiver
than from a high-powered one.
Technical Assistance or Service
If, after following the hookup directions, you experience difficulty, please double-check all
wire connections. Should you isolate the problem to the speaker, contact the authorized
Polk Audio dealer where you made your purchase, or contact Polk Audio Customer Service
at 800-377-7655 (M-F, 9-6 EST, US only) or via email polkcs@polkaudio.com. Outside the
US, call 410-358-3600.
Amplifier Power Requirements For Polk/MOMO Subwoofers
Using one subwoofer, we recommend an amplifier with a power rating of at least 200 watts
into 4 Ohms (x1 in bridged mode). If you have a noisy car or intend to play your system at
loud listening levels (or, you really wanna pound), more power will be necessary to achieve
the best performance. More power is always good.
Polk/MOMO’s Carbon Series of High Power Amplifiers make great companions for these
subwoofers. The Carbon Series is competition quality; three super powerful compact amps
built to deliver more watts per dollar no matter what your amplification needs. There’s a
bridgeable 4-channel model, a bridgeable Stereo model, and a Mono amp for dedicated
subwoofer amplification. Each model features the exclusive Polk/MOMO Pre-EQ Switch,
which optimizes the crossovers for use with Polk/MOMO Ultra High Performance Speakers
and Subwoofers. Match up your components and your speakers, and you can’t get better
optimized performance.

amplifier recommendations.
