The db models have been styled with “tuner” automotive enthusiasts in mind—from the wheel style grilles to the textured driver cones, db says “hot car.” But Polk's db series offers much more than great styling. The full force of Polk Audio’s award-winning engineering went into developing high performance to match the cosmetics. All of the components in the db Series benefit from Polk’s Dynamic Balance technology that stems from a joint research project between Johns Hopkins University's Center for Non Destructive Evaluation and Polk Audio.
The new db Series has been built tough to withstand the rigors of exposure to the sun, water and salt to earn Marine Certified status. db Series speakers are perfect for use in boats of all types.
