Celestion LF Cast Chassis Ferrite CF1830E

* 18" ferrite magnet, cast aluminium chassis LF driver delivering 700Wrms (AES Standard) power handling and 94dB sensitivity

* 3" high temperature, multi- layer voice coil for greater motor force

* FEA optimized magnet assembly delivers highly symmetrical cone - movement, leading to exceptionally low harmonic distortion

* Balanced Airflow Venting (BAV) on the front-plate increases airflow to provide enhanced cooling

* Dual Magnet Motor (DMM) incorporates a secondary magnet used to increase overal motor force (Bl) without the need for any additional increase in magnet size

* "Multi-roll" surround provides exceptional linearity at extremes of cone excursion

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.
