Celestion - FTX1225 300W 8ohm - Coaxial
Altoparlante coassiale da 12" con chassis in fusione d'alluminio, magnete in ferrite, bobina da 2.5", potenza 300Watt, impedenza 8ohm
Caratteristiche
- 12" coaxial loudspeaker with 300Wrms (AES standard) power handling and 97dB sensitivity
- Full range frequency response: 50 - 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
- 2.5" edgewound copper clad aluminium voice coil wound on high temperature glass fibre former
