Polk Audio

Our take on the Polk Audio db501

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 db501 speakers are engineered to fit 5" openings, featuring 4" polymer/mica woofers with 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.

Highlights:

  • 5" 2-way car speakers (pair)
  • 4" Dynamic Balance polymer/mica composite woofer with butyl rubber surround
  • 3/4" liquid-cooled silk/polymer composite dome tweeter

    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.

    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 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.

    2004 Nissan Frontier CC install...

    Written By CrazyCarl, Northern VA on Thursday, April 26, 2012
    Crutchfield Customer Review (What's this?)
     
    Well made speakers that install easily on 2004 Frontier. Edge of screw holes need to be clipped but metal is soft enough standard nippers work great. Included wiring harness for t-shape connector makes rest of install easy.

    Speakers are still breaking in but you know anything will be better than the stock foam surround with paper cones.
    Pros:
    Easy to install and sounds good.
    Cons:
    Little bit of customizing needed but nothing anyone with simple tools can't handle.

    Good Choice

    Written By CJ, Angola, NY on Thursday, March 29, 2012
    Installed in a 2003 Nissan Frontier
    Crutchfield Customer Review (What's this?)
     
    Installed these in the back doors of my 03 Nissan Frontier and the sound was awesome! I am not using an amp to power them at all. I just have a double-din Pioneer stereo that I also installed myself. Chatted on the online chat with Jenny and she recommended this set plus the 6 1/2" for my front doors. Those sound great too! She also found that it was saving me $$ because when I bought this set the other ones came half off! So it fit my budget and truck just right!!
    Pros:
    Everything good and installation was easy!
    Cons:
    none

    Polk does it again!

    Written By Roadnuts, CT on Wednesday, January 18, 2012
    Installed in a 1993 Volvo 240 Series
    Crutchfield Customer Review (What's this?)
     
    I bought the Polk DB series speakers for my 93 Volvo 240 sedan. Unfortunately the stock size speakers are only 4" front and 5" rear. I did not expect much sound or volume from such a small package. After doing some light customizing to get them fitting properly, I fired them up powering them only with my new Kenwood X695 radio. Wow! I can't believe how much sound comes from these tiny speakers! I added an MTX powered sub while I was re-doing my stereo for some thump in the trunk. These speakers keep their clarity even at high volumes, and reallyperform wonderfully even with just the Kenwood receiver powering them.
    Pros:
    Great sound even with the small size. (I used 4" and 5" coax) Speakers have an excellent fit and finish. I even used the included grills for my front speakers.
    Cons:
    None!

    Good looks, good fit

    Written By Jon M, Big Lake, MN on Monday, May 02, 2011
    Installed in a 1992 Honda Accord EX
    Crutchfield Customer Review (What's this?)
     
    Good, clear sound from these little guys. Installation was easy and with
    Crutchfield's instructions, took no time at all. As these are pretty much the only 5"
    model speaker, they are sometimes the only choice. Luckily, they are a great
    speaker.

    Polk 5" door speakers-Great Improvement!

    Written By Elle, Whitley city, KY on Wednesday, April 13, 2011
    Installed in a 1996 Toyota Avalon
    Crutchfield Customer Review (What's this?)
     
    I am very pleased with my recent speaker purchase. After wonderful customer
    service over the phone, I took Tyler's recommendation and selected these.
    They were as easy to install as he had said-with great instructions- and sound
    sooo much better than my previous ones. I didn't replace the back ones only
    because of the age and mileage of my car.
    I'll definitely keep purchasing from Crutchfield for their expertise and value
    pricing.

    92 Toyota 4Runner - Yes, it does fit!

    Written By BrianC, Dallas, TX on Wednesday, March 23, 2011
     
    The "outfit my car" guide says the back panels in my old 4Runner require 5 1/4"
    speakers, but when I tried to install them, they were too big and I found the
    previous replacements were 4". I measured them and found the hole to be 5
    inches!!! NOTE: This is when putting them in the original ported, amped, boxes
    that are still in place. These work perfectly! I hope they correct the guide
    for all those old 4Runners that are still on the road.

    As far as the sound, they are limited on bass, but what do you expect from 5"
    speakers. I have matching 4" up front and the sound is clean and accurate; just
    as I'd hoped. I can always at a subwoofer later.

    Great Little Speakers

    Written By Rob, Tampa, FL. on Monday, March 07, 2011
    Crutchfield Customer Review (What's this?)
     
    Great sound from these speakers. Even using a 45 watt amp they hold their own. They
    are what they are so don't look for tremendous bass - that's what subs are for. Beautiful
    sound. Get these and you won't be disappointed.

    Perfect for a motorcycle!!!

    Written By Jeff, North Central Illinois on Wednesday, April 21, 2010
    Crutchfield Customer Review (What's this?)
     
    Installed these in the fairing of my '03 Goldwing in less than 1/2 hour, very
    close fit with minimal alterations. The basket on the 501's is a little smaller
    than the Honda speakers, so the ends of the holes needed to be clipped out. The
    sound is great...much better than the paper-coned junk that Honda
    installed from the factory. Now to buy another set for my passenger...

    These speakers sound great! They were a perfect fit in the front doors of my 95 Toyota Paseo! I purchased them from the Crutchfield Outlet. Saved twenty dollars on them just because the box was open. Speakers were still in perfect condition. Would recomend these speakers!

    Polk Audio db501

    Written By Anonymous, Madison, IN on Tuesday, October 13, 2009
    Installed in a 2004 Nissan Frontier
    Crutchfield Customer Review (What's this?)
     
    Pros: Great value. Very easy to install in rear doors of 2004 Nissan Frontier. It took maybe 45 mins. for both sides. I used the Nissan grilles. These speakers sound great paired with the Polk db 651's up front. They are hooked up to a Clarion head unit. No amplification. These speakers sound as good as any aftermarket speakers I've owned (I've bought way too many - anyone remember Cricket?). You can't beat these for the price. I also highly recommend Crutchfield's Outlet. I saved 10 or fifteen bucks just because the speakers had been opened.

    Cons: None - do your homework - and you won't be disappointed (Crutchfield's comparison feature is incredibly useful).

    May be great, but I'll never know

    Written By James, Near Greenville, SC on Tuesday, March 03, 2009
     
    These may be great speakers, buy I'll never know. Contrary to what the Crutchfield site says, they do not fit in the front doors of a 1991 Audi 200 with a factory Bose system.

    That car has an amplified speaker enclosure in each front door, with a recess for a 4" speaker with three mounting holes in a triangular arrangement. The Polks have four mounting holes in a square arrangement. There is no way to make a square speaker fit down into the triangular recess.

    Removing the entire speaker enclosure is not an option as that would leave no place to mount the speaker.

    Great Sounding Speakers

    Written By Vincent, Central California on Friday, March 28, 2008
     
    Finally got around to changing the front speakers in my wife's car. She is using a Sony Head Unit CDX-GT320 which puts out 17w RMS per speaker. These 5in speakers replaced the 4in paper stock speakers. A BIG IMPROVEMENT!!! Also, easy to install. The hardest part was I had to drill 4 holes. The total time was less than 2 hours. ( I am Slow)
