Celestion FTR18-4080FD 1000W 8ohm LF Ferrite

Descrizione

Celestion – FTR18-4080FD 1000W 8ohm – LF Die Cast Chassis Loudspeaker – Ferrite

Altoparlante da 18 con chassis in fusione d’alluminio, magnete in ferrite, bobina da 4″, potenza 1000Watt, impedenza 8ohm

Caratteristiche

– 18″ ferrite woofer provides 1000Wrms power handling (AES Standard) and 97dB sensitivity

– 4″ high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression

– FlexirolTM surround for greater excursion control

– Double suspension for exceptional linearity at the highest excursions

– Low frequency response, down to 30Hz

– Smart chassis design minimises acoustic distortion

– Specially treated, weather-resistant cone

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.
