4" Coaxial

The Polk DB+ Marine Certified Series was designed for big sound and optimized fit for just about every vehicle & application.

Everything you love about Polk's Dynamic Balance technology-that rich, clean, full-range sound is built into this marine-tough, yet ruggedly sophisticated new series. And with its universal fit, it can be installed in any vehicle: Automobiles, motorcycles, boats, ATVs - you name it.

It offers a range of eight sizes in total: six different coaxials from the 4" to the 6" x 9" and also includes two component systems.

Enjoy a rich, clean, full-range sound with our patented Dynamic Balance technology engineered into every DB+ speaker.
