Mid-bass 12", 450W AES, 900W Program |  |
|
|
|
Medios-Bajos de 12” de Alta Potencia y sensibilidad, excelente linealidad con una muy baja distorsión. Construcción de bobina, y materiales de cono diseñados para soportar potencias de 400 Watt RMS.
Aplicaciones
Una respuesta lineal por encima de los 3 Khz gracias a un conjunto de masa en movimiento muy liviano hace hace que el MB12G301 sea una muy buena solución para sistemas de alta calidad de dos o tres vías. La bobina de aluminio garantiza una eficiencia muy alta junto al factor de resonancia apropiado para una buena respuesta en bajos.
