Everything you love about Polk's Dynamic Balance technology -that rich, clean, full-range sound-is built into the marine-tough, yet ruggedly sophisticated, DB+ series. And with its universal fit, it can be installed in any vehicle: Automobiles, motorcycles, boats, ATVs-you name it. High Performance Factory Upgrade Upgrade from your OEM speaker system toward a bigger, fuller, high-performance sound. The high-grade materials used in our DB+ Series ensure you get an audio system that's designed and engineered for clear, full range sound that will last much longer than your factory setup. 
These speakers also feature non-resonant materials so you get extremely clear highs, mids and lows no matter what you're listening to through our patented Dynamic Balance (DB) Technology. Universal Fit The new DB+ series has been updated so you can enjoy a simple drop in installation in any vehicle including cars, boats, ATV's -- you name it. Its new shallow tweeter design ensures your factory speaker grille re-installs with ease for a flush, seamless look. 
This quick and easy experience also ensures a faster installation process so you can get back to what matters with our great sound always along for the ride. Marine Certified The DB+ Series is IP65 rated so it's dirt- & water- resistant. It also has been tested for salt-fog, UV and humidity. A big part of that marine certification also means that each speaker has a non-corrosive plastic grille, a polypropylene UV tolerant cone, waterproof inner and outer surrounds, and stainless steel mounting hardware, ensuring that it's fully protected against the elements.
