Helix 2 Ohm slim 8" woofer - pair

 

Features

  • Exceptional cone excursion – ensures high sound pressure levels and impressive low-frequency reproduction
  • Hybrid flat woofer concept – a perfect balance between a powerful subwoofer and a mid-woofer driver that covers a frequency range from 25 to 500 Hz
  • Chassis with 1 x 2 Ohms single voice coil for maximum power output of the amplifier
  • Minimum installation depth – an innovative basket design with only 47 mm installation depth for the use in restricted mounting spaces
  • Compact dimensions with maximum performance – despite the small outer diameter, this woofer comes with the same cone area known from typical 200 mm chassis
  • Lightweight polypropylene cone which provides essential stiffness for phenomenal sound performance
  • High-tech polymer composite basket reinforced with glass beads for enormous rigidity and minimized ringing
  • Powerful magnet system for high efficiency and optimum impulse response
  • Perfect for difficult applications – e.g. can be installed under the seats in various BMW models or as front subwoofer in Mercedes cars
