Features Include

  • 10" neodymium mid/bass unit offers 250Wrms (AES standard) power handling and 96dB sensitivity
  • 2.5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
  • "M-roll" surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range
  • Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio
  • Intelligent heat management in both chassis and magnet assembly design further minimizes distortion
