Celestion LF Pressed Chassis Ferrite TF1230

* 12" Bass and mid-range driver providing 94dB sensitivity and 350Wrms (AES standard) power handling

* 3" high temperature copper voice coil wound on polyimide for increased reliability

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

* Double roll surround for greater excursion control

* For use in 2-way or compact 3-way systems

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.

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

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