About the Polk Audio db5250
Dreaming about better sound in your car audio system? Do you want lows that are full and definitive? Highs that resonate with clarity? Stop dreaming! Polk's db Series db5250 component system uses 5-1/4" Dynamic Balance polymer/mica woofers to produce full, rich lows that are free of detail-robbing distortion. Rubber surrounds, Kapton voice coil formers, and pole plate heat sinks protect the woofers against the stresses of heat and time.
The liquid-cooled silk/polymer composite tweeters can be mounted in either flush- or surface-mount cups to project detailed highs where you want to hear them. The 2-way crossover networks (4,000 Hz, 12 dB/octave) ensure smooth, well-balanced output, with built-in protection circuitry to guard your tweeters against accidental damage from high power.
Don't limit yourself to only using these speakers in your car they've passed tough environmental testing that certifies them for marine use as well.

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 Woofer: 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.
Kapton Voice Coil Formers: The low-mass 2-Layer 1" Kapton Voice Coil formers are lightweight for high sound output. Kapton's high melting temperature ensures high power handling and excellent reliability.Pole Plate Heat Sinks: The pole plate heat sinks promote better heat dissipation for superior power handling and reliability.
Silk/Polymer Composite Tweeters: The 1" liquid-cooled, silk/polymer composite tweeters provide clear, detailed highs.
Marine Certified Tweeters: Polk db Series speakers are built to withstand exposure to moisture and UV rays, so they work well in boats and cars.
Mounting: The supplied mounting cups allow you to surface- or flush-mount the tweeters. The tweeters swivel in the flush-mount housings, allowing you to adjust them for optimum imaging.
