绿宝石(Emerald)系列的产品是乐富豪扬声器中最高级的产品,它包括二路分音的“EM93”和“EM95”,三路分音的“EM93”和“EM97”,另外还有一种中置音箱“EM Centre”,共四款型号。此系列采用原木箱体,有玫瑰本色、蔷薇木色及轻橡木色可供选择。而且由于采用了电脑设计箱体,即由电脑模拟音箱箱体,分析所有会引致音染和失真的不良振动,务求将失真减少到最低电平,使音质更上一层楼。绿宝石系列不但中音效果出色,你音效果更是一流。
中/低音单元采用谐振特少的全新“三文治”结构。其中一层为塑料聚合物,一层为矿石,一层为塑料。这种塑料不但坚韧而且具有高刚性,可保证低频的重播,而矿石的磨擦消耗可吸收一些有害的中频谐震。这种中/低音驱动单元可承载较密集的功率,并能输出强劲的低音。高音单元的投射角度经电脑重新设计,配合低音使用时,可以发挥更佳的定位及音响效果。内部的发烧级分音器采用经过精挑细选的元件,以进一步提高音质及减少损坏机会。
为了进一步确保稳定性,EM-95在主驱动单元箱体下方还设计一个空腔,用户可将将清洁的矿沙填充到这个空腔中,自由调校重量,以改变低音效果。经过以上处理后,无论低音音盆如何运动,扬声器都会屹立不动。这时所听到的空气运动便可以与音盆的运动完全一致。
普通扬声器的分频器都配备有滤波网络,可将高频和低频信号分隔开,使它们分别达到高音单元和低音单元。但是这些网络的存在会导致驱动单元难以加载到功放上,使音色显得粗糙生硬。绿宝石系列采用了昂贵的Zobel配对网络,并重新平衡电子滤波器,使功放更易于推动,并改善低频动态。
还行啊。我买了,好久了都没有一点问题。
