Celestion FTR12-3070C 350W 8ohm LF Ferrite

Descrizione

Celestion – FTR12-3070C 350W 8ohm – LF Die Cast Chassis Loudspeaker – Ferrite

Altoparlante da 12″ con chassis in fusione d’alluminio, magnete in ferrite, bobina da 3″, potenza 350Watt, impedenza 8ohm

Caratteristiche

– 12″ ferrite mid/bass driver provides 350Wrms (AES standard) power handling and 96dB sensitivity

– 3″ high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss due to thermal compression

– Low frequency response, down to 40Hz

– Intelligent heat management in both chassis and magnet assembly design further minimizes 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)Tested as per the EIA-426-A standard.

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

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

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