Priced Per Pair

Note: Polk Audio specifies the nominal impedance of these speakers to be 2.7 ohms. The product box states the impedance to be 4 ohms and the speaker magnet shows 2 ohms, this has been confirmed by Polk Audio to be an incorrect specification. The product manual is correct in stating the nominal impedance of the MM series of speakers to be 2.7 ohms.

Speaker Specifications

Series
This is the manufacturer product line of speakers.
MM / Mobile Monitor (Polk)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
4" x 6"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way Plate
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Silk-Polymer Composite
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Woven Glass Fiber
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Butyl Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
150 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
50 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
90 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
70 - 25000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2.7
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Yes
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
1-3/4"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
2"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5-15/16" x 3-7/8" 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
No

Great sound from a small speaker

November 14, 2013

I have a pair of these in my 1992 Chevy reg cab pickup. I have a Kenwood head unit powering these and a pair of Pyle dash 4 x 6 too. Loud and clear is all I have to say. Great speaker for the money.

Impressive sound range at a good value!

August 7, 2012

I searched through a dozen or more different speakers in this size and couldn't find any that could handle the power that I wanted to put to them. These had the highest power ratings that fit my budget. I didn't like the plastic mounting tabs, and even though I was weary of them breaking; I still managed to break one that I needed. Great sound for the size / value.

Good little speakers

December 6, 2011

I got these to replace the factory rear speakers in my 02 Silverado ext cab truck. They are a lot louder and crisper than the factory speakers. I'll admit though, the factory speakers had a little more bass than these, but you don't buy 4x6's for bass anyway. I'm sure the SQ will only improve as they continue to break in. I'm sure it will be an improvement when I get some more power running through them as well. Like some other reviewers have stated, the speaker mounting frames are made of plastic. If you are not careful you can overtighten the mounting screws and break the mounting tabs. If you just take your time and use common sense (and do it by HAND, not a power drill/driver) you'll be OK. Overall another great sounding set of speakers from Polk Audio! FYI. If you plan on using the included mounting screws, be sure you have a metric allen wrench set handy as they are allen head screws.

Nice clean sound

February 23, 2010

These speakers are great, they have crisp clean hi's and the mid-bass has a little punch to it. I can actually feel it in my front doors, and they are installed in my back doors, so quite a punch from such a small speaker. I'm very pleased with the loudness, and quality, I just cant wait to put them on an amp.

Warm Polk Audio sound and Killer Looks!

October 29, 2009

I purchased these to replace a set of $60 Pioneer speakers on my rear deck. The difference in sound quality is impressive. The MMs have a much warmer, and yet clearer sound than the Pioneers. In my opinion they also blow the Polk Db series out of the water. The separate "tweeter/round mid" design, is far superior to the elliptical design. You get what you pay for! I am using a simple 4*16 Watts RMS Single Din Alpine Head unit to power all my speakers. While an amp would obviously be better, this unit has more than enough power to drive these speakers. I matched the rear MM461p, with a set of MM5251 components in the front. I just wished I could have fit some MM6501s in the front door panels, to get slightly more front mid-bass, since I don't have a Sub! The MM series speakers are in my opinion some of the best mid-priced speakers Polk has ever made. Unlike Infinity or even Mb Quart speakers, all Polk MMs offer a very warm sound (lower frequencies), therefore not having a sub is not the end of the world! I was so happy with these, that I installed MM6501s (Front) and MM651s (Rear) in my other car!

Good for a 4x6

October 20, 2009

I bought this to replace the infinity kappa 4x6's I had in my front doors. These sounded a lot alike until the tweeter. This is by far the better tweeter and is much more smooth but it cant be adjusted like the kappas. The problem I have with these speakers is that they are 4x6's. I am not a big fan of them and if I would do it again I would probably go with a high quality 4" speaker.

Good sound and excellent product for my needs

May 14, 2013

I purchased this to replace the rear deck speakers in my 2000 Porsche Boxster S. Porsche originally used two 3" paper cone speakers on each side which were poor from the beginning, but since nobody made anything to fit I put up with it! But after this much time, the paper cones and thin foam surrounds would crumble if you touched them, so it was time to find a solution. The first problem was that I needed to create an entirely new mounting plate that fit into the Porsche rear deck assembly but had greater space for a new speaker system. After looking at many alternatives, I created a new mounting surface from Lexan that was designed around the Polk MM461p speakers. While there are undoubtedly better speakers in the 4x6 or 4x6 plate category, the 461p not only fit the bill from a cost / performance standpoint, but it's unique oval plate allowed me to fit it into the tight space allowed by Porsche's rear deck. Even with the 461p having the smaller footprint than any other 4x6 plate, I needed to trim some of it away in order to squeeze it in, but far less trim work with my Dremel tool was needed than would have been required with any other plate speaker. After creating a dense foam spacer to use between the Lexan and speaker plate surface, everything was mounted using nylon screws / nuts and then mounted. Thankfully, everything fit and worked perfectly the first time! And the reason for the speakers is of course to improve the sound, and these made me realize just how poor the original speakers were! Even with the stock HU and amp, the difference in performance was obvious and worth all of the effort.
