About 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.

Product Research
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.

Been said many times, but definitely true in this case. Best bang for buck. Awesome sound and clarity. I listened to these in the store along with the comparable Infinity, Alpine, and Rockfords and this set had the best overall balanced sound. Buy em.
