来自http://www.zaphaudio.com/,同时参加测评的还有seas,vifa,scanspeak等数十款球顶高音。测量的参数包括频响,失真,后延等,我把对hivi的评测结果的描述摘出来,并给出大意(外文不灵光,无法准确翻译),供大家参考。括号中是价格:
Hi-Vi SD1.1 ($13) - "A" version tested. Nice performance for a tweeter of this price, and probably worth the few bucks more than the K1, but there are some consistency issues. Twin impedance peaks cause a slightly bumpy low end that smoothes out in box with typical baffle diffraction peaking. Slight rise in the top octave goes to flat a few degrees off axis. Make sure you have the shiny dome shown on the right. The dull one on the left measures horribly.
Hi-Vi SD1.1 ,13美元(约合人民币100元每只)测量了其中“一个”版本(按:一致性不好的意思),对于这个价位的高音来说表现良好,可能也值得比K1多几美元,但有某些共同的问题。阻抗的双峰造成低端响应的一些不平,高端的上翘在离轴几度时变平些。应该买球顶膜光亮的,另一个没有光泽的测起来很糟糕。
Hi-Vi TN28 ($13) - Bonus points for a neat looking top mount design. Minus points for energy storage at 8kHz. Tested in a typical configuration on top of an enclosure. High F5 at 1.6kHz will melt your ears if crossed over too low. Poor performer overall.
Hi-Vi TN28,13美元(100块)。箱顶安装的设计很好看,是个好处。缺点是8Khz处有能量积累。装在一个箱体顶上后测量。如果分频点太低,在1.6K Hz处高的五阶失真将让你的耳朵难受。总得来说表现糟糕。
Hi-Vi K1 ($9) - Smooth response. Shielded magnet, rather large 116mm flange. Low Fs for a tweeter with no rear chamber and a solid pole piece. High F5 below 2.2khz. Average to slightly high IMD. (not shown) Cross LR4 @ 2.2kHz or LR2 @ 3kHz for best results. Decent performer in a garbage price range.
HI-VI K1,9美元(70块)。平滑的频率响应。加防护壳的磁体相当大,直径达到116mm。Fs(就是F0)较低,没有后腔和solid pole piece(不懂怎么翻 ) 。2.2KHz以下有高的五阶失真。稍高的互调失真。2.2KHz四阶或3KHZ二阶分频结果最好。在垃圾价格系列(我们的hivi可是说这些单元是“顶级”啊)中表现还行。
Hi-Vi X1R ($9) - Worst performing tweeter in this group. I have to wonder if they were somehow defective, but my two samples measured the same... then went in the garbage. A dome material that's too light and flexible plus ferrofluid that's too thick = no impedance peak and horrible distortion.
Hi-Vi X1R,9美元(70块?X威网站上可是六百三十五啊!!!)这一批中表现最糟糕的高音…………我曾怀疑它们是不是有什么缺陷,但我这两个样品测起来是一样的…,…算是垃圾(原文就是这么写的“garbage",垃圾或废物的意思)。球膜材料太轻,太软,而且磁液太稠,阻抗峰没有,失真可怕。(我的天啊!!!这就是国内卖得比seas,vifa还贵的X威!!!) |
