PRODUCT SPECIFICATIONS
PRODUCT CODE: 28/CF1840H-4
PRODUCT BRAND: Celestion
DESCRIPTION:
18" ferrite magnet, cast aluminium chassis LF driver delivering 1000Wrms (AES Standard) power handling and 98dB sensitivity
4" high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing performance loss through thermal compression
Triangulated coil reinforcement reduces moving mass, thereby increasing sensitivity, while maintaining a long Xmax
Finite element analysis optimised magnet assembly delivers remarkably low harmonic distortion and very high motor strength
Smart chassis design minimises reflections back onto the cone, significantly reducing acoustic distortion
Intelligent heat management in both chassis and magnet assembly design offers increased output level
