Polk Audio DB651S Slim-Mount 6.5" Coaxial Speakers bring you superior looks and sound at a price that makes high performance affordable to everyone. The new slim mount design with a short tweeter post makes for an easy fit behind factory grilles. The polymer/mica composite mineral filled cone is stiff yet lightweight and brings you big sound with little distortion. A 19mm liquid-cooled silk-polymer composite dome tweeter with neodymium magnet creates clear, detailed highs. The Pole Plate Heat Sink promotes better heat dissipation for superior power handling and reliability. A multi-hole mounting pattern and shallow depth make for easy drop-in installations in practically any car on the road. Polk db Series speakers are built tough to withstand the harshest environments, so they are perfect for use in boats of all types.
