Polk Audio db501
5" 2-way car speakers
Our take on the Polk Audio db501 by Crutchfield's Leigh Schoettinger
Give your music new life
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. And Polk certifies their db Series speakers for marine applications, so they're a great choice for your boat, motorcycle, or ATV.

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.
