Speaker - Celestion, 21", NTR21-5010JD, 1600W, 8Ω
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
