Wilson 也不是无谐振，也是巧妙的利用谐振，就因为谐振给利用成良性元素，故应说成是无有害谐振。

威马兄没有好好读这篇Wilson的文章吧. 虽然Wilson开头说At Wilson Audio we understand that enclosure materials can resonate during playback with musical material. This resonance can color the music or sound, accentuating particular frequencies and effectively masking others
在Wilson Audio我们懂得封闭材料在播放音乐的时候会有谐振.这种谐振可以给音乐或声音带来染色, 加强特定的频率, 有效的屏蔽别的频率.
然后比较了一大堆材料, 首先是实木, 微粒(锯末? )板 ,MDF, 认为实木谐振太大,会有严重谐振和高频失真, 不可以用,锯末板稍好, MDF更好些. 但还是达不到要求.
Solid Woods are unacceptable due to longitudinal flexing along the natural grain of the wood.
Particle Board is better than wood but is still subject to severe resonance and tonal problems.
MDF is best applied in less critical areas of the cabinet.
然后说Wilson自己研究了两种特殊材料, 大大减小了谐振. 一种是Methacrylic/Ceramic compounds , 甲基丙酸烯和陶瓷的混合物
一种是High Density Phenolic 高密度石碳酸(聚合物? )
甲基丙酸烯和陶瓷的混合物具有extremely low natural resonant frequency (极低的自然谐振频率)
高密度石碳酸是By far this is the best, most non-resonant material we have ever encountered (到现在为止我们发现的, 最好的, 最没有谐振的材料,
然后说这两种高级材料通常不是为市场使用的 (价格超级昂贵? ) , 他们被Wilson开发使用当然是为了高级的应用.They are used only if their benefits are suited to the application at hand
然后说使用Wilson研究的这些指示, 我们可以创造出富有动态, 致力于忠于录音的高还原的器材.
By applying our research and knowledge in this field, we are able to deliver a product that is dynamic, involving, and true to the intent of the recording.
由此, 大家可以看出, Wilson的目标就是无谐振. 他们的研究目标也是无谐振.
