Celestion LF Cast Chassis Ferrite FTR08-2011D

* 8" ferrite magnet driver providing 200Wrms (AES standard) power handling and 93dB sensitivity

* 2" high temperature copper voice coil

* Suitable for line array applications, utilizing a space-efficient octagonal chassis profile

* Optimized flux distribution in magnet assembly provides low harmonic distortion

* "M-Roll" surround provides progressive excursion control, generating a smooth frequency response

* Intelligent heat management in both chassis and magnet assembly design offers reduced thermal compression

8 Ohm Frequency Response

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.

3. Measured on axis at 1W, 1m in 2p anechoic environment.

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