Descrizione
Celestion - CF1840H 1000W 4ohm - LF Die Cast Chassis Loudspeaker - Ferrite

Altoparlante da 18 con chassis in fusione d'alluminio, magnete in ferrite, bobina da 4", potenza 1000Watt, impedenza 4ohm



Caratteristiche

- 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 increases stiffness with no additional 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

Note

(1)Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.

(2)Continuous Power Handling is defined as 3dB greater than the AES rating.

(3)Measured on axis at 1W, 1m in 2pi anechoic environment.

(4)Xmax derived from: (voice coil winding width-gap depth)/2.

(5)Small signal parameters measured after unit subjected to pre-conditioning signal.
