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 versatile db5251 component speaker system features 5-1/4" 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 1" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. You can surface- or flush-mount the tweeters with the included swivel-mount cups. Just aim the tweeters so they broadcast toward your ears, creating a powerful stereo image.
External crossovers direct the right frequencies to the tweeters and woofers to maximize their performance, and their housings let you hide all wiring for a clean, professional look. 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.
Ready to tackle the car or marine environment, Polk db components will provide you with great-sounding music in your vehicle or on the water.
