Celestion CF18VJD 1600W 8ohm LF Ferrite

Celestion - CF18VJD 1600W 8ohm - LF Die Cast Chassis Loudspeaker - Ferrite

Altoparlante da 18" con chassis in fusione d'alluminio, magnete in ferrite, bobina da 5", potenza 1600Watt, impedenza 8ohm

Caratteristiche

- 18" ferrite magnet, cast aluminium chassis LF driver delivering 1600Wrms (AES Standard) power handling and 97dB sensitivity

- 5" high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing sensitivity loss through thermal compression

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

- Vented front plate increases airflow to provide enhanced cooling

- Twin demodulation rings reduce flux modulation, minimizing electromagnetic distortion

- Double suspension and "multi-roll" surround provide exceptional linearity at extremes of cone excursion
