首先,铝合金不等于没有共振,铝合金的在中频的共振还很大,建议看stereophile的实际测试,yg和magico a5的共振都很大,The accelerometer revealed the 1.2 cabinet to have relatively strong resonances at 580 and 795Hz, the 1.3 cabinet at 560 and 795Hz (fig.3). Although these frequencies are well above the passbands of the 1.2 and 1.3 woofer enclosures—you would not, therefore, expect them to be excited with music playing—I could faintly hear the midrange resonances when I used a stethoscope to listen to the woofer enclosures while the speaker played pink noise
铝合金在低频确实是很干净的,在中频则共振的声音是偏温暖,有种人体体温感的,不是干冷薄的。铝合金的单元、避震都是这种走向。
铝合金箱体的声音不等于铝合金共振的声音,还有一部分来自于箱体,也就是喇叭背波在密闭箱体传出来的声音。等于把乐器关在铝合金房子里面传出来的声音。这部分音量往往低于主音箱发出的声音40db以下,这些声音铝合金箱体的往往确实是轻微的偏干和闷一些。这种音染对于所有非障版非屏风非等离子的音箱都有。其实也不是什么很影响音乐播放的大问题。
不同材质的箱体的音箱,只要做到好的性能,都能做到好的声音。
