Polk precision

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 db691 speakers feature 6"x9" 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 1" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. The 3/4" dome supertweeters add even more sparkle to reproduce your music's natural intricacies. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.

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

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 two-layer 25mm 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 Tweeter and Super Tweeter: The speakers feature 1" liquid-cooled, silk/polymer composite tweeters and 3/4" liquid-cooled, silk/polymer composite super-tweeters for clearer, more accurate mids and 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.

Flat Spider: The speaker utilizes a flat spider for faster, longer excursion linear motion.

Pole Plate Heat Sink: The speaker's pole plate heat sink promotes better heat dissipation for superior power handling and reliability.

Woven Leads: The speaker features flexible woven leads sewn directly into the spider for greater reliability.

Basket: The speaker is housed in a solid, acoustically inert stamped steel basket finished in rustproof gun metal gray.

Grilles: Strong ABS plastic grilles are included. These computer optimized grilles are based on exclusive MOMO designs.
