CF1830E 700W 8ohm LF Ferrite – Celestion
codice: PPEK15300057
Celestion – CF1830E 700W 8ohm – LF Die Cast Chassis Loudspeaker – Ferrite
Altoparlante da 18" con chassis in fusione d'alluminio, magnete in ferrite, bobina da 3", potenza 700Watt, impedenza 8ohm
Caratteristiche
– 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
