很难说27TDFC和27TDC哪一个更好,我个人感觉是扬声器好坏不能靠价格来判断。
27TDFC有磁液,27TDC没有磁液。前者的瀑布图更干净一些,承受功率更大,分频点能更低。如果分频点需要分到2K,那么我不假思索的会选择27TDFC。
但是对于这两个纸盆低音,分频点2K5也都很合适,27TDC没有磁液显然也很合适,它的互调失真比27TDFC稍小一些。
这样很难取舍,看个人喜好了。
27TBFC/G是铝镁合金的金属膜高音,多数人凭心理感觉就不喜欢这款高音。据老外说,它和27TDFC的磁路是一样的。其实它在这三者之中有最小的失真,最干净的瀑布图。不要被频响曲线那里20K的跌落所吓倒,实际表现不是这样的,一般人想要声音表现它都能提供。
这三者中,我个人最喜欢的是27TBFC/G
摘抄几段国外对27TBFC/G的评价:
1:The Seas 27TB series tweeters are an aluminum tweeter based on the same motor used in the fabric dome versions. I chose the "TBFCG" version, which has ferrofluid and a rear chamber. Don't let the slightly rolled off top octave fool you... this tweeter will have all the "air", "sparkle" and [insert audiophile verbage here] that you'll ever need. But the best thing about it is its smooth response, low distortion and low frequency power handling ability.
2:The Seas 27TBFCG is one of the best tweeters at any price
3:The Seas 27TBFC/G is the new low cost testing champion. It gets this by having notably improved nonlinear distortion numbers higher up in the spectrum while having the same great low end performance.
4:The tweeter is the famous H1212. Delicious tweeter and though he certainly aluminum soft sound and very detail rich.
5:What beats the R2904/7000 ring radiator?
Well it depends.
Seas 27TBFC/G can be considered even if it's cheap.
6:Simply put, because it *is* the best in the group, even regardless of cost. If the Millennium only cost $30, I'd still buy the 27TBFCG. Of course the build quality of the Millennium is excellent. I love the thick metal frame. But the 27TBFCG sounds and measures better.
7:Yes, Seas 27TBFCG is one of the best sonding things I ever heard compared to it' s cost
8:Very smooth response, down a few dB at 20kHz. Very low distortion of all types, particularly the near non-existant high order harmonics. No notable energy storage problems.
当然这不意味着27TDFC和27TDC不好,其实他们和27TBFC/G之间的差距是很小的。甚至在某些程度上,27TFFC和他们三者之间的差距也是很小的。从某些业余的说法来看,软球顶也许和纸盆搭配音色还更连贯呢。 |
