Celestion - CF1025C 300W 8ohm LF Ferrite

Celestion - CF1025C 300W 8ohm - LF Die Cast Chassis Loudspeaker - Ferrite

Features

- 10" Mid/bass driver delivering 99dB sensitivity and 300Wrms (AES standard) power handling
- FEA optimised magnet assembly and suspension delivers highly symmetrical cone movement leading to exceptionally low harmonic distortion
- Balanced Airflow Venting (BAV) increases airflow to provide enhanced cooling
- Twin demodulation rings reduce flux modulation, minimizing electromagnetic distortion
- "M-roll" surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range

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