UNE PIECE DISPONIBLE
Haut-parleur 18" – 1500 W rms - 8 ohms
Domaine d'application : Le LF18X401 de RCF a été réalisé par RCF pour prendre place là ou il est nécessaire d'avoir une forte puissance et lorsqu'un besoin de grande excursion est indispensable comme pour de la musique "live".
Le LF18X401 peut prendre place dans des caissons en bass reflex ou en horn. La grande excursion lui permet également de prendre place dans des conditions d'écoute critique comme en Sub pour gros monitors de studio.
Caractéristiques du LF18X401 :
Bobine mobile de type inside/outside de 4" montée sur support en fibre de verre.
Puissance de 2400 watts en programme continu.
Sensibilité de 98db 1w/1m avec une bande passante de 30Hz a 1KHz.
Xmax : +/- 50mm avant dommages.
Poids : 13.3Kg
Applications :
• The LF18X401 is ideal for use in applications where sizable amounts of low frequency, long excursion and low distortion acoustic power is desired.
• The robust mechanical design and optimised weight of the device make it desirable for use in fixed installation or touring professional loudspeaker systems.
• The transducer's low frequency extension, coupled with its extremely low generation of harmonic distortion, also makes it ideal for use within critical listening applications such as studio monitoring subwoofer systems.
