BWV / 株式會社 Eastern Sound Factory ~3 wayss speaker H-5

 

3 wayss speaker H-5

old mid driver ~Aluminum diaphragm

tweeter ~ Glass diaphragm

這款喇叭是日本 BWV 品牌 推出的旗艦落地揚聲器 H-5，它不是使用玻璃振膜作為中音單元。

此喇叭的各單元配置與玻璃振膜的實際應用如下：喇叭結構與配置：

最上方：配備了一個帶有方型擴散面板的號角高音單元~玻璃振膜

中間（被框選處）：它是這款喇叭的中音單元 ，但採用的是紙質或複合材料振膜

下方：配備了一個帶有特殊支架保護的低音單元 

玻璃振膜的真正位置：

該品牌（BWV / 株式會社 Eastern Sound Factory）確實以開發「超薄玻璃振膜（Glass Diaphragm）」技術聞名，不過在 H-5 揚聲器上，玻璃振膜通常是被應用於高音單元中，而非中間這顆錐盆中音單元。
