Woofer 18", 1000W AES, 2000W Program |  |
|
|
|
El LF18G400 es un woofer de 18” que tiene características de respuesta de frecuencia increíblemente lineales y un manejo de potencia muy alto.
El LF18G400 utiliza un Cono de fibra reforzado junto a un laminado de suspensión triple de alta excursión de geometría constante. Esta combinación provee una fuerza notable y una amplitud máxima de 52 Mm. de pico a pico. Otra de las características principales de este 18” es su pieza polar tipo T y la placa superior de 14 Mm. para mayor manejo y control de excursión.
Aplicaciones
El LF18G400 es ideal para su uso en aplicaciones donde se requiere de un increíble manejo de potencia, rango dinámico extendido y control perfecto. Ideal para gabinetes tipo Bass Reflex profesionales de alta calidad y sistemas con carga de bocina . El diseño mecánico, robusto y el peso optimizado para el altavoz lo hacen ideal para su uso en instalaciones fijas o para sistemas de parlantes profesionales portátiles.
