各位,“刹车”确是AT说的(源自对KAPTON/铝制音圈骨架各自特性的解释),请参阅它家网页上FAQ。摘选如下:
Kapton is a non-conductive material and is therefore not influenced by the eddy-current effect like aluminum, when situated in a magnetic gap.
In practice this means no mechanical brake and therefore a very high mechanical Q-factor and low Mechanical resistance.
Drivers with Kapton voice coil former often perform a more detailed midrange with higher dynamic and less coloration and distortion.
Due to the lack of mechanical brake, we do not recommend the use of Kapton drivers as bass driver, because if the x-max is exceeded there is nothing to prevent the driver from bottoming out. For sub woofer applications, please use drivers with aluminum voice coil formers. |
