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 tech-
nology 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—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 exten-
ded linear motion, optimized to achieve the longest throw
possible for the cone: “Big cone, big throw!”
• Huge, fire-retardant flat NOMEX
®
Spider allows exten-
ded 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 ampli-
fier, regardless of its wattage, is made to play at higher lis-
tening levels than its power can clearly produce. This is usu
-
ally beyond the “12 or 1 o’clock” position on the volume con
-
trol. 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 dif-
ficulty, 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 and Canada only) or via email polkcs@polkaudio.com.
Outside the US and Canada, 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.

Amplifiers, visit www.polkaudio.com, or consult your friendly
