Speaker - Celestion, 10", NTR10-2520E, 250W, 8Ω
Special Order Item
Speaker, Celestion, NTR10-2520E, 10", 8Ω.
Features:
- 10" neodymium mid/bass unit offers 250W rms (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 minimises distortion
