FTX0820 200W 8OHM COAXIAL/TWIN CONE

Celestion - FTX0820 200W 8ohm - Coaxial/Twin Cone



Features



- 8" coaxial loudspeaker providing 200Wrms (AES standard) power handling and 94dB sensitivity

- Full range frequency response: 70 - 20,000Hz

- FEA (Finite Element Analysis) optimized ferrite magnet assembly acts as common motor for both LF and HF drivers resulting in enhanced coherence

- Robust cast aluminium chassis is designed to minimize unwanted reflections, further reducing acoustic distortion

- Demodulation ring reduces flux modulation, minimizing electromagnetic distortion

- 2" edgewound copper voice coil wound on high temperature glass fibre former

- 100° nominal HF coverage
