Speaker Specifications

Series
This is the manufacturer product line of speakers.
db (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.
5" x 7" (also mounts in most 6" x 8" locations)
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
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.
Polymer/Mica Composite
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.
180 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.
60 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".
93 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).
52 - 22000 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.
4 ohms
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.
2-3/16"
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.
2-1/3"
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

Installed in girlfriend's 2009 Ford Focus. HUGE improvement over stock speakers! I was very impressed by the sound quality and range for a coax at this price point. Can't go wrong with Polk. Do yourself a favor and by the Metra speaker wire adapters...very convenient and saves a lot of time.

This is my first experience with polk audio, and I have no regrets on this product, great quality sound (like infinity), you don´t need much power to get them high.

I am going buy two pairs for a ford supercrew as the adveserting said can be fitted on 5x7 and 6x8.

August 18, 2012

I replaced the four factory speakers in my 2011 Ford F-150 with these db571 speakers a few weeks ago. I also installed an amp and sub which are only powered when the engine is on. I noticed that even without the sub and amp, the sound quality is much much nicer than what I had with the factory speakers. Would recommend these to anyone.

Awesome Speakers!!!

June 5, 2012

I have a 2006 Ford F350 with a factory head unit and no amp. I am by no means an audio expert but here's my opinion: Immediate difference from stock speakers. I can run these speakers at full volume with no distortion. Plenty of bass, but also controlled and tight. The sound quality doesn't change at any volume. I recommend these speakers for anyone with a 5x7 speaker. The only reason i rated durability a 3 is because I just got these and don't have any reference on durability, but they feel and look well built.

Easily the best bang for your buck. I put 4 of these into my 09 F150 and have enjoyed them ever since. Crystal clear highs and acceptable lows. The bass won't shatter windows but it's tight and crisp which is all I wanted. If you're looking to wake up the neighborhood with your bass get a sub.

Needs to be amped

March 1, 2012

I put these in my wife's Mazda 5 being powered by a Pioneer GM-D9500F. They sounded very good and provided enough bass I decided not to sacrifice the little cargo space I had for subs.

Currently they are installed in my Ford Freestyle with no amp. They sound better than the factory speakers but are nothing compared to how they were amped. Bass is non-existent at best but the highs and mids are good. Because they are marine certified they are a little thicker and heavier. This slows down response so some songs sound a little muddled. As long as they are amped it's not noticeable.

Bottom line is I loved these speakers they provided all the sound I wanted and were a great price. Unfortunately for my tastes I have to factor in an amp to go with them.

Excellent 5x7 by Polk

November 14, 2011

I have driven Ford vehicles for many years and I always replace their crappy stock speakers within a week or so of buying a vehicle. At first I tried to install my older Punch 6x8s (P1683) that I had pulled out of my Expedition prior to trading, in the doors of the F-150, but they were just a bit too large and I didn't want to carve up the doors of my beautiful new truck. I have always used Rockford Fosgate or Kicker for car audio but have been using Polk Audio for my home theater, so I decided that since my home theater Polk speakers sounded so great that I would try some in my F-150. I just put these in over the weekend and right out of the box they sounded BETTER than any Fosgate or Kicker 5X7 I have ever heard, excellent sound. I am running them off of a Fosgate Punch 400.4 which is rated at 50 watts rms x 4 (actually puts out about 70x4) and the 5x7 sound amazing. Nice tight midbass and very clear highs. I can now say that I have converted from Fosgate to Polk on door speakers, still stickin with Fosgate for my subs and amps, though I am curious to hear some Polk car audio subs.

Good speaker for the money

October 19, 2011

Installed these in replace of stock mids on a 2012 Ford Mustang. Good speakers but because they handle more watts than the stock speakers the factory cross over made the mids too high and offered less bass. Not the fault of the speakers though.

April 20, 2011

I was surprised at the sound of these speakers. I run them straight from my 25 watt Pioneer stereo unit wich might only be 12.5 watts at 4 ohms, anyway in the back and 2 custom 12 in. subs I created from Sonic Electronix sales that are run with an amp that puts out 200 watts at 4 ohms. x 2 channels and they balance out perfectly. I also have 2 5x7 Rockford Fosgates in the front door I got at Sonic Electronix

Excellent Polk Car Speakers

March 29, 2011

I installed 2 sets of db571 speakers in my 2004 Mercury Mountaineer 6 mos ago. My concern was that I would not have sufficient bass response w/o a sub, however, these speakers produce ample bass and great sound (after I set the sound dynamics on the new Eclipse H/U which I also purchased from Sonic). Overall, very satisfied.

Did the research and read the reviews for this particular model, which were all positive. Items match the specs I was looking for, which were consistent for the application I have in mind. The best reason, however, was the fantastic price I got them for! Beats the other well-known vendor hands-down!
