Review on Polk Audio DB652 Ultramarine Speakers by Michael Nastanovich

I work on my boat with 100W RMS (pure JL Audio amplifier) as additional speakers between two Pioneer 8 sets and a 12 subwoofer, so I turn the gain down a bit. on them for balance. They play clear, like a bell, at a very good volume. They're harsh until you tune and tame them, though, and even then they're a bit harsh to my ears, so EQ needs to be added to pull out some of the mids and roll them past the crossover. I only tested for 20 minutes during setup but for the price. Good buy. Let's see if they can handle the boat.
