Celestion LF Pressed Chassis Ferrite TF1225e

* 12" Bass and mid-range driver with extended low frequency response


* 2.5" edgewound voice coil provides 96dB sensitivity and 300Wrms (AES standard) power handling


* Kevlar-loaded cone with sealed surround and damping for reduced distortion


* Double roll surround for greater excursion control


* Suitable for use in 2-way and compact 3-way systems



8 Ohm Frequency Response




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


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