Our new Polk Audio db Series Car Speaker video features Ken and J.R. pointing out some of the things that make these speakers so popular with our customers.

J.R. explains that the designation "db" stands for "dynamic balance." Polk Audio db speakers have carefully balanced woofer cones to help minimize resonance and deliver cleaner sound. Ken points out that these speakers fit most cars, and that Polk even offers a 5" model.

And Ken mentions that the speakers are certified for marine use, which means they're built to withstand exposure to the elements -- and even J.R.'s squirt bottle.
