Polk Audio Db400

First and foremost a speaker company, Polk Audio designs and builds speakers that give you top-end performance, even at middle-of-the-road prices. And the db Series' cutting-edge looks, textured woofer cones, and MOMO-inspired, wheel-style grilles add a stylish touch to your ride as well. The db400 4" speaker features a polymer/mica composite woofer for crisp and clean midbass. The woofer's rubber surround improves performance and lengthens the speaker's life span. You'll enjoy the smooth highs produced by the sweet-sounding silk/polymer dome tweeters. Instead of the simple high-pass filter found in most car speakers, a more sophisticated 2-way crossover network ensures that woofer and tweeter handle only the appropriate frequencies. The result? Clean sound and accurate imaging. These speakers aren't just limited to use in your car — they've passed tough environmental testing that certifies them for marine use.
