Speaker - Celestion, 18", CF1830E, 700 watts
Special Order Item
Speaker, Celestion, CF1830E, 18 in., 8 ohm Features:
- 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 and suspension deliver 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 overall motor force (Bl) without the need for any additional increase in magnet size
- “Multi-roll” surround provides exceptional linearity at extremes of cone excursion
