Design curato, collaudato e messo a disposizione direttamente da Celestion.
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
