## Description

Polk Audio DB692 6" x 9" 3-Way Coaxial Speaker for Car & Marine. The Polk Audio DB692 3-Way Speaker features a 6" x 9" polypropylene woofer cone, a 3/4" silk dome tweeter, and a 1/2" super tweeter, with a built-in crossover, that delivers smooth and precise sound. The marine and car speakers' Dynamic Balance technology uses laser imaging to reduce resonance, resulting in a wide response and low distortion. The Polk 6x9 Marine Speakers are versatile, with mounting hardware included. The included grilles have a bold design that adds a touch of style to your vehicle's interior, making them a good choice for customized installation. Polk Audio tests the DB+ marine speakers rigorously for environmental effects like sun, moisture, and extreme temperature changes. As a result, they're even certified for marine applications, making them a great choice for your boat. Polk Audio's DB+ Series subwoofers are a great value, delivering smooth, powerful bass. Used by marine and car audio enthusiasts, as well as audiophiles, in boat and car audio installation - especially for road trips and marine drives. So, if you want to upgrade your sound system without breaking the bank, the Polk Marine Speakers' DB+ series is an excellent option. Polk's advanced technology and engineering bring out the best in class audio with powerful speaker series, smart speakers, and soundbars, allowing you to sit back, relax, and listen with your heart.

Review: Great quality speakers and competitively priced - My oval JBL Marine speakers finally started crackling after 17 years of use, so it was time to replace them. I searched high and low and settled on these speakers. Aside from the fact that they fit almost perfectly in the existing holes (I say "almost" because they are a tad smaller than the JBL speakers), the sound was fantastic; I was able to crank the volume with no distortion and solid bass/treble. The price was definitely competitive too; not the lowest, but certainly not the highest. I would definitely recommend these for any boat.
Review: Great buy - Great speakers, I installed them in a boat they sound great
