More Control, More Power,
More Everything

The dX3055 component system gives you the installation flexibility of the 5.25" dX5510 driver combined with the small but powerful 1" dX3000 tweeter. And if you're a control freak, you'll be happy to know that the dX Crossover in this system gives you the kind of audio flexibility that suits your taste as well.

The dX3055 features:

  • Blue tri-laminate silk composite dome tweeters for more accurate response, superior detail and high power handling: "Bright Without Bite."
  • Dynamic Balance mineral-filled polymer cone driver for clear, well-defined midrange and great bass, too.
  • Pivoting tweeter, which allows you to aim the tweeter in the direction that yields the best high frequency response and soundstaging.
  • Neodymium (NdFeb) magnets offer powerful magnetic energy from small magnets. You get great sound and a speaker so small that it is easy to fit and mount in a wide variety of locations.
  • Three-position tweeter level switch for precise high frequency optimization for your car.
  • Adjustable crossover point and slope provide 12 different combinations of settings, allowing you to precisely tailor the system sound to suit your car's acoustics and your ears.
  • Coated baskets and gold plated terminals resist rust and corrosion for years of reliable performance.
  • Polk's Dynamic Balance® technology for superior response with all kinds of music.
  • High-tech Elastomer rubberized-plastic surrounds for reliable durability and better tuning.
  • Aramid fiber spiders—the same material used in bulletproof vests—for linear response and wider dynamic range.
  • Extra long, precision wrapped, vented voice coils for superior cooling, longer linear throw, and high power-handling.

Flush and surface mount tweeter mounting cups are supplied.
