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 features 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.

All db Series speakers feature rustproof baskets and stainless steel mounting hardware, so they're suitable for marine use. If you're custom installing these speakers, the muscular ABS grilles will add a stylish touch to your car's audio system. Whether you've got a factory radio or aftermarket stereo, these efficient speakers will spice up your daily commute.
