不知跟scanspeak的softdome 9500比， 哪个的高音比较柔，高音延伸和结象较好??
SS softdome是我最目前想要得。。。。 |

两者级数差很远啊....
Seas通常比Scanspeak柔.. 而且Alnico磁铁属性也偏柔，再上频响曲线跟更大的振膜面积判断，35mm要刺耳是相当难的事= =（其实只要平衡度做好就不会刺耳）
论结象....35mm物理上可能没办法赢，但如果9500配对没35mm好（毕竟价格..），随时会不如..
向上延伸35mm惨败，但向下延伸又是35mm的强项啦～
Scanspeak中我最喜欢D2904/9900。独特的导波器，没液磁。价格跟9500也没差多少,,, |

wow! seas exotic 很贵哦！！ 竟然比SS 9500高几倍的价钱。。。
你觉得 DYNAUDIO 15W75-04 如何？跟eton kelvar比又 怎样？朋友刚好有对 dynaudio & eton 想卖？？ |

又是两个极端。怎么比呀
eton分音器很难搞，bass又难推出。Dy就容易搞得多～ |

你觉得DYNAUDIO 15W75-04 佩vifa ring radiator tweeter/ ss 9500行吗？可做到几多dB?? |

取决于DYNAUDIO 15W75-04的灵敏度，经过分音器大概还要扣1db左右...
很少见人用Dy中低音配Vifa/SS高音... 能不能配得上过半决定于分音器设计咯～ |

FM Acoustics煲电容法
http://www.fmacoustics.com/set_support.html
A little known fact is that electronics (of whatever brand) that have not been switched on for 4-6 months or longer should ideally be preconditioned with a variac. This way they can be "run in" at low voltage, starting at about 1/10th of the mains voltage (10V on a 100-120V mains or 20V on a 220-250V supply). Every 20 minutes the mains voltage can then be increased by about 10V.
This is because the electrolytic capacitors (that are used in most electronics) are electro-chemical components and age over time. When not having been used for a long time they do prefer a gradual rise in voltage. An immediate high voltage can weaken a component that has been "dormant".
So if you have a unit that has not been used for many months or years and uses electrolytic caps (and almost everything electronic does as there is no alternative to electrolytic caps in most applications...), bring it to a technician that has a variac and ask him to "run in" the unit as described above. You may be compensated for this care by a considerable increase in life expectancy and reliability.
好吧，与其说“煲机” 更准确的是“活性化”。
虽然资料里是说“4个月以上没开机”才用这招。但厂家说辞总是有保留嘛～ 我们不妨让新电容也用这招～ |

那顺便找翻译给你了
もう少し知られているという事実エレクトロニクス（どんなブランドの）を4-6ヶ月以上の理想的なvariacを前提にする必要がありますに切り替えされていないです。彼らの"低電圧で動作する"ことができるこの方法は、電源電圧（ 10Vの約1/10thでは100 - 120Vまたは20Vの電源では220 - 250V電源）を開始する。電源電圧が増加することができますし、毎週20分のため、電解コンデンサ（つまりほとんどの電子機器に使用されている約 10V.This ）電気化学部品や年齢を時間をかけている。ときに電圧が徐々に上昇を好むかは長い間使用されていない。即時高電圧は、 "休眠"されている成分を弱めることができるので、多くの場合は数ヶ月から数年に使用されていないと電解キャップを使用しています（と、ほぼすべての電子としては、電解キャップている場合には別の方法では単位がある...), variacしているが、ほとんどのアプリケーションと"で実行するように"とは、ユニット前述の技術を持ってきて、彼に尋ねる。このケアのための平均寿命と信頼性にはかなりの増加によって補償されることがあります。
而我个人建议的是，尽量慢慢充着上。对DIYer而言不需要用variac煲整架机（有些机过低电压还会开不到甚至会伤害到= =）。直接用DC稳压电供去喂独立每只电容。我的方法是更简单的串接电阻让电容慢慢升压......... |

第一个是“电子”“电气”“电学”（怕误会意思就用三个解释= =）....
其他的都是电容的意思
别告诉我你连英文“electronic”“Capacitor”都认不出？||| |
