Special Order Item

Speaker, Celestion, NTR21-5010JD, 21", 8Ω.

Features:

  • 21" neodymium subwoofer offers 1600Wrms (AES standard) power handling and 98dB sensitivity
  • 5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
  • Double suspension and a "multi-roll" surround provide exceptional linearity at extremes of cone excursion
  • Rigid lightweight carbon fibre loaded cone delivers improved performance and faster response
  • Intelligent heat management in both chassis and magnet assembly design further minimizes distortion
RoHS Compliant
