Infinity Kappa 62IX 6.5' Coaxial Speaker System

  • Infinity’s glass fiber woofer cones are lighter and stiffer with more cone-area than the competition , delivering increased low-frequency output and higher efficiency..
  • Edge-driven textile dome tweeters – These are not commonly used W-domes, but edge-driven textile dome speakers that will deliver broader and smoother high frequency response..
  • High output 2.5 ohm ohm architecture with low impedance voice coils enables the speaker to extract every watt from the amplifier and deliver peak power with ease..
  • Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time..
  • Infinity is in the business of designing reference quality speakers, and Kappa car audio speakers are no exception..
