Our take on the Polk db570

When it comes to sound in your car, you like it powerful, yet smooth. Polk built the db570 speaker for high efficiency, to deliver the big sound you're looking for, but with the refinement of speakers usually costing much more. This 5"x7" speaker combines a polymer/mica composite woofer with a rubber surround to keep the bass crisp and clean. You'll enjoy the lush high-frequency tones of the liquid-cooled, silk/polymer composite 3/4" dome tweeter.

Instead of the simple high-pass filter found in most car speakers, a built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging. Grilles are not included — factory grilles are appropriate for most installations.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.

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.

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

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.

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

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

Great Speakers

Written By Derek, Arlington, TX on Sunday, March 30, 2008
 
I bought these speakers to replace the stock 6"x8" in my '01 F-150. They
sound great!! The highs are much clearer at high volumes than the stocks
were. The reason the speakers get a 4 of 5 stars is because i could only
secure two screws, due to the fact that two of the holes don't line up. If
you are on a budget, but want to get some aftermarket speakers with
some power, go no further than Polk db 570's.

Bad Tembre

Written By IGO, Las Vegas on Friday, March 14, 2008
 
I wanted about 6% rear fill in a moderately extensive set up in my new Mazda3 Hatchback. At 100 watts rms per channel up front, a component set of Polk Audio db5251 does the job. I bought the db570 hoping for timbre matching with the front and I am powering them with an old Kenwood 50 x 2 amp. Gain and attenuation at the HU draw most of the SPL up front but there is a nagging presence in the rear and I can't EQ it to mimic the front speakers. These speakers, though I didn't expect the exact same quality, sound like mud compared to the front and they actually detract from the overall listening experience. They get a two because this is a higher end install and I expect in a less extensive system they would fare much better with the other gear.
They gotta go.

Great upgrade over factory speakers!

Written By Ed, Brunswick, Ga on Thursday, February 28, 2008
 
Just installed these speakers in 04 F-150 Super Crew and it sounds great over the factory speakers. I ran a Bose wave radio demo CD before the install, then again after, and the difference in sound over factory is incredible.
As far as installation, the side tabs on the front speakers had to be bent to allow the speaker to recess into the hole in the door mold, and only 3 screws lined up. Only 2 screws line up on the rear but still secured. Don't spend any money on radios, amps, or woofers until you install these speakers; you won't need them!

Sound good, didn't quite fit right

Written By EJ, Corvallis Or on Tuesday, February 12, 2008
 
The speakers sound fine and are well priced. They didn't quite fit my Escort and I think the way I made them fit probably affects the way the sounds negatively. The mounting holes didn't line up with the stock brackets.

Wow

Written By jmerr001, Columbus, GA on Wednesday, February 06, 2008
 
Bought these after looking at a set of Infiniti Reference speakers and talking to several folks. The agent at Crutchfield also said these would sound more natural and with the price of these... wow. I can't get enough of these speakers and the enhanced quality of my sound. From talk radio to rap to heavy metal, the bass and highs come in at amazing clarity. You won't be disappointed in these.

Delivery was right on time and allowed me to install them on the same day I received them. I will certainly order again from Crutchfield.

Great deal!

Written By Thomas, Chicago on Monday, January 14, 2008
 
I bought these to upgrade my factory rear speakers. These things sound great and fit in the factory locations perfectly. The sound is much sharper from these. There is not much bass from these speakers but if you want bass then get a sub. Great bang for the buck, even better if you are looking to replace factory speakers.

Nice speakers, great price...F-150 install Tips

Written By SuperSTX, TN on Wednesday, January 09, 2008
 
I just ordered these from Crutchfield, they came quickly and well packaged as expected. The installation instructions from Crutchfield were dead-on, and the included wiring harnesses made the install very easy.

However, I will say that these are recommended as a direct fit for the Ford F-150, and while they do fit in the factory opening well, you can only get 2 out of the original 4 screws into these speakers. If you put one in the top left and bottom right, it holds it nice and tight but there is no way to get all 4 original screws back in without some type of modification.

Other than that they are a huge improvement over my factory speakers (which were just terrible, Ford, in case you're listening).

Next up from Crutchfield is a new head unit to really make these sound great!

Did not fit

Written By chris, LaGrange, KY on Wednesday, October 03, 2007
 
Had to do alot of cutting and trimming to make these work and look good. Other than that these sound great. These are in a 1981 rabbit diesel w/kenwood 2035 receiver.

Great Choice

Written By Anonymous, Plano TX on Tuesday, September 04, 2007
 
I bought 2 pair of the Polk db 570 and replaced the door speakers of my 2003 Ford Expedition Eddie Bauer and I am very pleased with the results. I am using a Kenwood 8403 to power these speakers and they are holding up well. I kept may factory head unit and ran a MTX Re-Q and everything sounds great.
