Woofer 18", 700W AES, 1400W Program |  |
|
|
|
El L18S800 es el clásico woofer RCF de 18” de alta eficiencia.
Un diseño eficiente de bobina, conforma un peso de masa en movimiento controlado que hacen de este transductor la solución ideal entre muchos parlantes para compañias de renta. Una disipación térmica eficiente se lleva a cabo al forzar el aire el cual es parte de un volumen situado entre la campana y la placa posterior. La construcción de las bobinas, suspensión y materiales de cono son de tecnología de vanguardia para soportar 800 Watt RMS.
Aplicaciones
L18S800 encuentra su mejor aplicación en gabinetes del tipo paso de banda, bass reflex y sistemas con carga bocina. Es una solución perfecta para bass reflex compactos, música en vivo, cuando se requiere un máximo punch. Es uno de los transductores más rápidos en su categoría.
