Product features

Before replacing a factory speaker, check its mounting space, impedance and connection. HELIX Ci3 T20FM-AL MK2 is the HELIX speaker option described below. Its specifications help you match the driver to the amplifier and installation, rather than buying on diameter alone.

What it does

  • 0.75” / 20 mm performance tweeter with black aluminium dome for accurate, pure and detailed treble response
  • Refined highly efficient neodymium magnet for high magnetic flux linearity and optimised performance
  • Driver development verified with Klippel Analyzer System
  • Compact design and various mounting options for numerous installation demands
  • Mounting pods for flush mount and angle mount included in delivery
  • Designed for the optionally available car specific FlexMount20 adaptors which allow an acoustically optimised and professional integration in the original mounting location of the vehicle
  • Designed for optionally available, car specific WireKits which allow a non destructive integration
