Overview

Our take on the Polk Audio MM6501

Polk Audio continues its tradition of making brilliant-sounding speakers in stylishly designed packages — their Mobile Monitor (MM) Series speakers look great and sound even better. Each speaker utilizes an extra-strong, extra-small neodymium magnet that saves space and weight, allowing these speakers to fit into more places in more vehicles while still delivering a full sound with lots of kick. Their lightweight carbon composite frames provide strong, flex-free support for the speakers' motor assemblies.

Their lightweight carbon composite frames provide strong, flex-free support for the speakers' motor assemblies.

The Polk MM6501 6-3/4" component system features 6-3/4" woofers with honeycomb-textured woven glass fiber composite cones that respond very quickly for a clean, crisp, and powerful sound. Large voice coils — over an inch in diameter — give the speaker high power handling capability and extended reliability.

Separate 1" silk dome tweeters add a sweet high end that blends perfectly with the low notes, and swivel mounts let you aim the tweeters to produce a superior sound stage in your car. The external crossovers direct the signal flow so all your music stays in perfect harmonic balance, from the electric bass all the way up to the cymbals. A tweeter attenuation setting allows you to tweak the high-frequency level to your taste.

Important Note: These Polk speakers use a low-impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with virtually all factory and aftermarket stereos.

Note: Polk describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Great sound quality, crisp and clear.

Woofers

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.

Woofer Cones: Woven glass composite cones feature tremendous stiffness-to-mass ratio. Lower mass means faster transients and finer detail.

Butyl Rubber Surrounds: For a smoother response and improved durability, the woofers use butyl rubber surrounds. The airtight rubber surrounds stand up to moisture, sunlight and extreme temperatures while allowing long excursion linear motion and years of reliable use.

Neodymium Magnets: The woofer's neodymium magnets offer exceptional strength to performance ratio and is extremely lightweight.

Large Diameter Voice Coils: Large diameter, 30mm voice coils increase the woofer's reliability and power handling capacity.

Carbon Composite Basket: The woofer's carbon composite basket is lightweight and will not flex during music audio peaks.

Mounting: The woofer itself has 4 mounting holes for a standard 6-3/4" application. The supplied mounting ring has multiple mounting holes for 6-1/2" and non-standard 6-3/4" applications, allowing the speaker to fit more vehicles.

Grilles: Strong ABS plastic grilles are included. These computer optimized grilles feature a spoke-wheel design.

Marine Certified Woofer: Polk MM Series speakers are built to withstand exposure to moisture and UV rays, so they work well in boats and cars. They also include stainless mounting hardware for corrosion and rust resistance.

Tweeters

Silk/Polymer Composite Tweeters: The 1" liquid-cooled, silk/polymer composite tweeters provide clear, detailed highs.

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

Mounting: The supplied mounting cups allow you to surface- or flush-mount the tweeters. The tweeters swivel in both housings, allowing you to adjust them for optimum imaging.

Tweeter Mounting Dimensions:

  Surface Mount Flush Mount
Mounting Height 1.015" 0.405"
Depth 0.75" (screw depth) 0.875"
Frame Diameter 2.0" 2.295"
Cutout Diameter   N/A 1.945"

Crossovers

2-Way Crossovers: Each outboard crossover features a 12dB/octave high-pass network for the tweeter and a 12dB/octave low-pass network for the woofer.

Tweeter Attenuation Switch: You can adjust the output of the tweeter to match a level appropriate to your vehicle or your system. On the end of crossover (opposite the terminals), the tweeter attenuation switch can be set to 0dB or -3dB.

Electronic Tweeter Protection Circuits: Each crossover has a built-in protection circuit that guards the tweeter against accidental damage from high power.

Crossover Connections: The crossover inputs and outputs are screw terminals. The crossover housing is vented, giving you a choice of hidden wire channels for easier, more professional-looking installs.

Mounting: There are two mounting holes in the base of each crossover.

Crossover Dimensions: Width = 4.265", Depth = 3.635", Height = 1.175"

Why did you buy this?

It fit and meets my minimum specs [ kevin  Oct 16, 2016 ]
Weatherproof and great sounding speakers for my jeep [ jason  Oct 04, 2016 ]
Lee in tech support recommended these after listening to my needs and answering my idiot questions. He discussed 4 different options, but kept coming back to these. [ scott  Oct 02, 2016 ]
Needed marine rated components for my Jeep, throughout. The's had best mix of price and performance. [ Michael  Jul 13, 2016 ]
They sound awesome! Great clarity and separation, my son even chose these for his system. My amp shorted out and puked killing one of mine, along with fresh amps I ordered the same speakers to keep the great sound I've enjoyed. Everyone who rides in my car says they are one of the best they've heard; great match for my JL Audio 10W6v3-D4 sub. Besides ... They have my "initials" already marked in them :). MM [ Michael  May 22, 2016 ]
Polk Audio quality and longevity in the business. Great products that deliver on sound/ [ DAVID  May 07, 2016 ]
I don't know much about Polk audio, but most reviews I've seen have been very positive, and Polk seems to have really good customer support as long as the item was bought through one of their authorized dealers. [ John  Apr 23, 2016 ]
