Polk Audio

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Our take on the Polk Audio db571

by Leigh Schoettinger

Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk's db571 speakers feature 5"x7"/6"x8" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 3/4" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.

 Whether you've got a factory radio or an aftermarket stereo, these efficient speakers will spice up your daily drive.

    Features

    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.

    5x7/6x8 Speaker: This speaker can be used in both 5x7 and 6x8 applications. The supplied mounting adapter ring allows the speaker to adapt to a 5x7 cutout when top mounted, and should be used to achieve a good seal when bottom mounted in both 5x7 and 6x8 applications.

    Woofer Cones: Each speaker features a Dynamic Balance polymer/mica composite mineral-filled cone. The cones are stiff and lightweight for big sound and low distortion.

    Butyl Rubber Surrounds: For a smoother response and improved durability, the woofers use butyl rubber surrounds.

    Kapton Voice Coil Former: The low-mass, 2-layer Kapton Voice Coil former is lightweight for high sound output. Kapton's high melting temperature (725°F) ensures high power handling and longer reliability.

    Silk/Polymer Composite Tweeters: The 3/4" liquid-cooled, silk/polymer composite tweeters provide clear, detailed highs. The tweeters use neodymium magnets.

    2-way Crossover Network: The built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging.

    Crutchfield Customer Review (What's this?)
     
    These speakers went well in my car and were a huge improvement over the factory ones. On has had its tweeter blown or otherwise developed a rattle in the speaker itself in the past couple months but for the price I paid for them, it's hard to be too upset over that

    I replaced factory speakers in my 02 Ford supercrew. Nice upgrade in sound and they seem to be well built. The instructions that were included made it easy to install. I had all 4 replaced in a little over an hour.
    Pros:
    good sound and easy to install

    Polk Audio speakers

    Written By David C, Hiddenite NC on Monday, March 11, 2013
    Crutchfield Customer Review (What's this?)
     
    I wasn't happy with the factory speakers in my 2011 F150, so a friend recommended Crutchfield. I went to their website and found many after market brands to choose from. I called and spoke to a salesperson who helped me narrow down what I was looking for and offered suggestions. The Polk Audio db571 speakers easily installed and sound great, especially for the price. I am very pleased with the quick delivery and overall experience with Crutchfield! I have already recommended Crutchfield to my friends and family.
    Pros:
    Easily installed without needing adaptors to mount.
    Cons:
    None

    put these in a 2008 Mazdaspeed3 GT front and back doors, these sound 100x better then stock. They dont really have that much bass but thats ok because Crutchfield sells them and Polk Audio makes them. Easy install fit like a champ, no mods needed.

    Excellent Value

    Written By Pat, White Plains, NY on Sunday, February 10, 2013
    Installed in a 1991 Ford Mustang
    Crutchfield Customer Review (What's this?)
     
    Excellent clarity to these speakers. They have great punch and performance while playing everything from Classical to Heavy Metal. High frequencies are awesome, and very crisp. The mid levels are very specific, and the speakers don't muddy a track in any of the songs I threw at them - you can hear the music as if each bandmember had his own speaker within the speaker. The low frequency tones are clear and do not hum, but rather thump, bump and kick effectively. I have a $150 price range Kenwood Receiver powering these Speakers, and play off a USB.
    Pros:
    Crisp well executed sound - resolution is EXCELLENT. Remnd me of themon Kardons in my 2013 ML.
    Cons:
    Mounting Brackets required modification to fit application. No big deal...

    Crutchfield Customer Review (What's this?)
     
    Needed to buy speakers because 1 of the factory spaekers in my '06 F-150 was dying. Was only going to buy 1 pair of Alpines but it happened that Crutchfield had a buy one get one half off sale on the Polks so I got 2 pairs of them.. Was told by the customer service guy that there would be a big difference in sound even though I'm using the factory head unit. There wasn't. There was a very slight improvement in bottom end but the highs are harsh and strident and there is a large hole in the mid range. Either these are not very good or the factory speakers aren't that bad. I'm disappointed in their sound especially considering that I have a full set of large Polks for my home theater system and couldn't be happier with those. Maybe everything would improve with a new head unit or an amp.
    Pros:
    Decent low end for this type of speaker
    Cons:
    No mid range, harsh highs

    Not enough bass, need a separate sub. But sounds really good w/ the addition of a decent sub & fine tuning.

    Crutchfield Customer Review (What's this?)
     
    These speakers immediately gave a noticible improvement over my factory speakers, which is what I was trying to accomplish since buying my 2010 truck.
    Pros:
    Very easy installation, exact instructions for my truck, sound is what I was looking for.
    Cons:
    After installation, needed to remove door panel again to turn one speaker around because a speaker wire was pulled out when the power window was rolled down.

    surprised

    Written By Pat A., Bloomington,Il on Saturday, July 28, 2012
    Crutchfield Customer Review (What's this?)
     
    I just purchased a new ( to me ) truck. A 1999 F 150 super-cab. It had already installed an aftermarket receiver. It's a Alpine CDE-102, sounded really good. My Dad thought it was the best system he has herd in a auto before. I thought it was lacking just a bit, it was good I just thought it could be a little better. I thought the speakers were factory and thought aftermarkets would make it sound like I wanted. Didn't know exactly what I wanted but I knew a good place to look. (Crutchfield ) after surfing the site looking at all the what fits in my truck I still wasn't sure I was looking at punch from a e-mail ad , so I called the adviser hot line. the Adviser ask several questions my music and how I liked to listen and recommended these speakers. I received them in 2 days. I removed the door cards and found kenwood tri-axles. "Oh crap" not factory speakers!. Well I bought these might as well try them. Thanks Curtchfield adviser I could not be happier. these are clear and crisp. the highs and the mid-range is right there. can't wait to get my sub in now thanks again.
    Pros:
    good crisp highs and mids. very clear

    Great speakers for price and brand. Got buy one second 50% off. Boston makes clean sound without distortion. Not going to blow out windows but clean and crisp. Running off factory deck till satalite radio contract done. Going to power with aftermarket deck soon. These speakers need power to show full potential(like most aftermarket) but make a difference with crappy factory unclean power. Not as dynamic as infinity but alot less expensive.
    Pros:
    Cleans up factory "buzz" great bargin.
    Cons:
    Need clean power to show full potential

    A clear upgrade from the Factory speakers in my 2001 F-250 Crew Cab. Perfect fit to the stock locations, and with the included wire harness adapter from crutchfield, I had 4 speakers installed in 45 min. Not a lot louder with the factory deck, but much clearer.
    Pros:
    Great mids and highs with no distortion
    Cons:
    I dont have enough wattage yet to reallyget all these speakers have to offer.

    Cheap, easy upgrade for crap 2011 F150 stock speakers.

    Written By Mike S., North Ridgeville, Ohio on Wednesday, May 02, 2012
    Installed in a 2011 Ford F-150 XLT
    Crutchfield Customer Review (What's this?)
     
    Vast improvement over stock. Not what I would consider audiophile quality, but considering I am using the stock factory head unit, and no amps, subs, ect. I am satisfied with the sound - for now. Install was fairly simple, thanks to the instructions Cruthfield supplied with the speakers. If Crutchfield can stand a little constructive criticism, one of the first steps in the install instructions is to remove the cover behind the inside door handle, to access the bolt, but all the sheet shows is the cover already removed. It does not give a clue HOW to remove it! I found you need to get behind this cover on the lower left corner, while holding the handle away from the door, as if you were opening it, with some sort of hook type device, and pull sharply. I have an old window moulding clip removal tool that worked perfect for this. once I figured this out, the rest was fairly simple. I would recommend connecting the power window switch, and make sure everything is out of the way from anything that moves BEFORE you reinstall the door panel. I used cable ties to secure the adapter cables to a factory harness inside the door. Interesting observation, I think I may have figured out why the stock speakers sound so bad. On the speaker magnet of the FORD speaker, it reads, plain as day "MADE IN CHINA". Sure am glad I bought American! These must have cost Ford all of 80 cents each!
    Pros:
    Price, if you get the buy one - get one half price deal. Seem to be made from quality materials. Installation instructions included - for your vehicle.
    Cons:
    Not a "perfect" fit. Had to use some creative screw angles to use the factory holes, or you can redrill two of them.
