Special Order Item

Speaker, Celestion, NTR12-3018D, 1", 8 ohm Features:

  • 12" neodymium woofer offers 350W rms (AES standard) power handling and 98dB sensitivity
  • 3" 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 minimises distortion
RoHS Compliant
