以下是引用水仙在2007-04-29 21:33:12的发言:The goal for this tweeter series was to create a transducer that has a frequency response that is flat to above 20K, and where the distortion is far lower than normal and more friendly to the ear. The tweeters represent a unique approach to tweeter design that has resulted in unrivaled performance, as well as in several patents (dual concentric diaphragm, wave-guide center plug).
这个引用,我猜想是VIFA自己的吧.足够是权威的解释了.
我是六,七年前听过,但是并没和其它同类型高音单元作过认真的对比,抱歉.
初步判断:
是个好单元,有VIFA专利保护,环状振膜和中间那个相位塞是有道理的.
没细想,或者说,没条件去仔细研究了,中间那个相位塞究竟有什么作用?
我记得它的高度大约是10MM(?),
那么它能对多高频率的声波起作用?
如果10MM是四分之一波长的话,全波长就是40MM,即4CM,
那就相当于9500HZ.
那是能在声频域的高端起到作用了.

以上是我的拍脑袋的随想,有心人可以作些像样的测试和分析的了.
