Speaker - Celestion, 15", FTR15-4080FD, 1000W, 8Ω
Special Order Item
Ferrite magnet cast aluminium chassis driver
- 15" ferrite woofer provides 1000Wrms power handling (AES Standard) and 97dB sensitivity
- 4" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
- Flexirol TM surround for greater excursion control
- Double suspension for exceptional linearity at the highest excursions
- Low frequency response, down to 35Hz
- Smart chassis design minimises acoustic distortion
RoHS Compliant
