More Control, More Power, More Everything

The dX Component Loudspeakers contain amazing technology -- the kind that makes them tough enough to take the heat, and powerful and efficient enough to inspire many a road trip.

  • Dynamic Balance mineral-filled polymer cone driver for clear, well-defined midrange and great bass, too.
  • Co-molded polymer/rubber surround provides superior bass response and will not dry rot like foam surrounds.
  • Coated baskets and gold plated terminals resist rust and corrosion for years of reliable performance.
  • Aramid Fiber spiders deliver better sonic imaging and more dynamic range. (And they can really take the heat of action, because that's the same material used in bulletproof vests.)
  • Vented voice coil provides superior cooling and higher power handling.
