看看这位老兄对D27的看法.
A word to the wise: Use only new D27 tweeters from Madisound or Solen. Do not buy D27's used off ebay or direct from another person unless the seller gives you an actual tested impedance curve. If they can't or just point you to a pdf file, don't buy. If they do send you a real tested impedance curve, don't buy if the Fs is outside 1000-1200hz or the impedance peak is outside of 15-25 ohms. In case you don't know what I'm getting at, this tweeter had problems in the past. Those have been resolved by Vifa, but the old problem tweeters are still out there.
一点明示: 仅使用来自Madisound或Solen新的D27高音。 除非卖主给您实际测试的阻抗曲线,不要买从ebay或直接从个人处购买的D27。 如果他们只是给您提供官方的pdf文件,就不要买。如果卖方确实提供了实测阻抗曲线,而FS超出1000-2000HZ,或者阻抗峰值超出15-25欧,也不要买. 实际上,这款高音有以前有问题。 虽然问题已经被Vifa解决了的,但老款有问题高音扬声器仍然流出来了。 |
