Mid-bass 12", 650W AES, 1300W Program |  |
|
|
|
El MB12N351 está diseñado para proveer una respuesta en frecuencia lineal con muy baja distorsión.
Una muy resistente estructura magnética de neodimio garantiza una precisión y dinámica excelente. Un diseño único de bobina de 3.5” brinda un alto manejo de potencia y es especialmente recomendada a comparación de la bobina estándar de 3”. El sistema de ventilación forzada, garantiza una muy eficiente ventilación de la bobina obteniendo así una compresión de poder mínima y un alto manejo de la energía.
