Overview

Our take on the Polk Audio db401

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.

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 db401 speakers feature 4" woofers made from a polymer/mica composite and 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.

These speakers feature stainless steel mounting hardware and db-design grilles that will add a stylish touch to your car's interior.

Fit just right in the dash of my 1990 Mercedes Benz 300E. Sounds amazing!

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.

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, 2-layer 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.

Heck of a deal. Good reviews from many. I'm not an audiophile, and with the top down these will sound just as good as any. [ Jamie  Dec 04, 2015 ]
