在首届国产音响器材大展以及’95广东国际音响大展中,有一款型号为新德克C2.0的书架式音箱受到与会者的广泛好评,尤其是它重放人声和弦乐的表现特别令人难忘。本文就这款音箱的设计和制作心得作一介绍。图1是新德克C2.0的结构尺寸。它是一个内容积为18升的标准倒相式书架音箱,采用中密度纤维板,前后面板厚25mm,其余为18mm。表面是精致的原木皮或进口PVC装饰,Φ50的倒相孔设计在背面,以求较强的低频反射和较宽的声场效果.箱内璧贴有特殊的阻尼物质。该音箱采用双线分音,因而背面用一个四位镀金接线盒,分音器就固定在接线盒上。C2.0高音是许多世界名牌音箱都采用的丹麦vifa软球顶单元,其性价比高是一个重要原因。低中音为新德克羊毛纸盆
