摘录了这个评测网页的一段：The nature of the sound signature is very detailed and transparent. It seems to me that they are much closer in that to speakers with hard cones, but at the same time they do not lose the timbre shades so inherent for speakers with soft cones. At the same time, the distinctive softness and a kind of “veil” in the range above 800 Hz that can be heard from ScanSpeak 18W/8531G00 and other speakers from this family, or Usher 8948A, are completely absent. Very dynamic and contrast sounding. PTT6.5W04-01A has surprisingly low aerodynamic noise at an amplitude of 10 mm at a frequency of 30 Hz. Here they are quiet, unlike, for example, ScanSpeak Illuminator 18WU/4741T00.
这个评价意思是这个喇叭出来以前，市面上一系列最好的6.5寸非金属盆喇叭都有800hz的“口罩音”？
