Our take on the Polk Audio/MOMO MM6

Polk Audio teams up with MOMO (the accessories specialist) to bring you the incomparable sound and undeniable style of the MM6 6-3/4" component system. Polk's Dynamic Balance technology minimizes speaker resonance and distortion for ultra-accurate performance throughout the frequency spectrum.

Polk Audio teams up with MOMO (the accessories specialist) to bring you the incomparable sound and undeniable style of the MM6 6-3/4" component system. Polk's Dynamic Balance technology minimizes speaker resonance and distortion for ultra-accurate performance throughout the frequency spectrum.

The 1" silk dome tweeter broadcasts clean, detailed high frequencies for "bright without bite." Surface- and flush-mount cups are included for tweeter installation flexibility and pinpoint imaging. The woofer's cast aluminum basket houses a polymer/mica composite cone and butyl rubber surround, delivering strong bass with lifelike extended midrange response.

The crossover features high-grade components, gold-plated terminals, 3-position tweeter level adjustment (0 dB, -3 dB, -6 dB), and a midrange extension switch (for installations where the woofer and tweeter are physically separated). The vented crossover housings allow the crossover components to stay as cool as they look.

Product Research

Additional Dimensions


Dynamic Balance Technology: Laser imaging research allows Polk to observe the resonances of different cone materials. Polk engineers have used laser imaging techniques to find the right combination of materials, geometry and construction needed to tune out response distorting resonances. The result is excellent bass and smooth, clear midrange response.

Cast Aluminum MOMO Arrow Basket: The futuristic-looking woofer basket is designed to mimic MOMO wheel designs. The basket is finished with diamond-polished silver metallic paint.

Woofer Cone Materials: The polymer/mica composite woofer cones produce rock solid mid-bass response and lifelike midrange detail. Each woofer is made with a light, but strong, woven carbon fiber dustcap to improve efficiency. The woofers feature 1.5" voice coils.

Motor Cup: The 14.4 oz. woofer magnet is covered by a metal cup made to match the basket's styling. The outside of the cup is finished with diamond-polished silver metallic paint. A red and black acrylic plate with a yellow MOMO logo and a Polk Audio logo is attached to the bottom of the cup.

Butyl Rubber Woofer Surrounds: The butyl rubber surrounds are airtight and durable for long-term reliability and superior bass response.

Tweeter Materials: The 1" dome tweeters are made with a red silk diaphragm for flat response, great inner detail and low distortion. Each tweeter features a neodymium magnet for ultra-high efficiency.

Tweeter Mounting Options: This system includes mounting parts and hardware for flush tweeter mounting and surface tweeter mounting. In both mounting configurations, the tweeters can be pivoted to "aim" their output for the best high frequency response and soundstaging.

2-way Crossovers: The included crossovers include a 12dB/octave, 3500Hz high-pass filter for the tweeters and a 12dB/octave, 3500Hz low-pass filter for the woofers. Each crossover includes a "mid-range extension" switch that allows you to turn off the low-pass filter and send full-range output to the woofer; this feature can be helpful in achieving a better blend of woofer and tweeter output when the two drivers are located far apart from each other. The high-pass filter is made with Mylar capacitor and air-core inductor components for better transparency.

Selectable Tweeter Output Level: Each crossover has a 3-position switch that allows you to select the tweeter output level according to system requirements and personal preference. The switches may be set to "-6dB", "-3dB" or "0dB".

Crossover Mounting: There are 2 mounting holes in the base of each crossover; screws to mount the crossovers are not supplied. The crossovers are not weather proof, so they should not be mounted in locations, such as door panels, that will expose them to direct contact with water.

Crossover Terminals: The crossover terminals are nickel-plated.
