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
