Polk Audio DB461P 4-by-6-Inch Coaxial Plate-Style Speakers (Pair, Black)
Polk Audio db461P 4" x 6" Coaxial Plate-Style Speakers bring you superior looks and sound at a price that makes high performance affordable to everyone.  A new 4" x 6" plate-style design affords easy installation into tight factory spaces.  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.  High and low pass filters deliver clearer, more accurate midrange and glare-free highs, with more natural-imaging than other speakers in this class that use single stage high-pass only filters.  Furthermore, the Pole Plate Heat Sink promotes better heat dissipation for superior power handling and reliability.  Polk db Series speakers are built tough to withstand the harshest environments, so they are perfect for use in boats of all types.  The db Series delivers classic Polk Audio performance and durability like never before.
