G90 是指镀锌板双面三点测量的平均最小重量为0.9oz/ft2，即SI 单位为275g/m2。 它们之间的换算关系是1oz=0.0284kg,所以0.9oz=0. 02556kg=25.56g 1ft2=0.093m2 25.56g/0.093m2=275g/m2。 所以SI单位标注为 Z275 。 依据以上换算，G与Z标号之间的对应关系如下： G90 ——Z275. G75——Z230. G70 ...

SB-G90M2的2路同轴扬声器单元是为再现中高频范围而新开发的，以实现清晰的声像定位和高音质，从而传递出流畅、情感丰富的音乐，同时继承了Technics不懈追求的点声源和线性相位概念。 原本形状的声学插头被安置在高音喇叭振膜的正面，提供了高分辨率音色再现能力和宽广的声场。 线性相位插头的尖端是由高模量、高密度的黄铜材料制成。 它可以防止插头因中音单元的振动影响而产生不必要的振动，从而提供清晰和低失真的声音。 当声波沿不规则表面传播时，由于表 …
