The Polk Audio/MOMO High Performance Tweeter is a masterpiece of miniature engineering and design. It brings stunning detail and beautiful highs to the MM Series Component Systems. And its precision German-manufactured red silk-composite "Mueller" dome does it without "biting."

  • Polk/MOMO is built tough and backed by a three year Parts and Labor warranty, the best warranty in the car speaker world.
  • It features a 1" aluminum ULV fluid-cooled voice coil and small-but-powerful neodymium magnet for high power handling and superior detail.
  • You can swivel mount it, too, for pinpoint imaging.
  • It's the perfect complement to the Polk Audio/MOMO line of High Performance car audio components.
