高音单元大比拼
从SCAN , VIFA , 到Hiquphon,惠威,常用的都函盖了.当然要感谢来自Zaph的工作!!!Scan-Speak 7000 ($398) - This driver is essentially the high end version of the XT25. Performance is indeed a small step up in all areas. Build quality is top notch with a thick metal flange that will never warp. Unfortunately, the price is ridiculous and value is low. Tested March 2008.
Seas Crescendo ($336) - Seas new flagship tweeter, very expensive. Great build quality and looks, visually matching the Nextel painted woofers. While it does perform a little better than the Millenium, it's still merely average in linear and non-linear distortion, and the price is ridiculous. Tested February 2007.
Scan-Speak 7100 ($285) - One of the ultra-high end tweeters from Scan-Speak, one step down in price from the 7000 ring radiator. Externally, the dome is similar to the 6600, but there are some differences in the damping coating and former, along with a different magnet structure and venting. A little more sensitive than the 6600. Very clean low end, and low harmonic distortion everywhere. A little ragged response in the top octave, but overall great performance. Note: this is the -01 version. Tested February 2007.
Accuton C23-6 ($262) - Very expensive ceramic dome tweeter. Slightly ragged response and related energy storage issue at 4kHz. Mild top octave droop. Excellent 2nd order HD. Exceptional tall order HD above 3Khz, but high 3rd order HD below. If you can fix the response curve in the crossover, this is generally a good tweeter. There are better in this group however, and for less money. Tested September 2005.
Seas Millennium ($224) - The definitive and popular high end tweeter. Decent 2nd order HD, disappointing 3rd order HD. Near perfect response curve. Physically well built with a distinctive and recognisable copper ring. Heavy, thick flange. Note that some folks have mentioned a peak in response at 12kHz. Not on mine however. Tested April 2005.
Scan-Speak 6600 ($220) - Also known as the "AirCirc" from it's unique magnet and rear chamber design. This tweeter very low non-linear distortion. It takes a few design elements from the XT25 and improves on a few things. Low end distortion is better, and off axis response is closer to normal for a 1" dome. The only negatives to this are a small dip in the top octave response, the high price, and some production variance over the years. Old/Other tests available. Tested May 2008.
Scan-Speak 602010 ($199) - This is the first tweeter to be released under Scan Speak's Illuminator line. It is a small flange neo magnet tweeter with a rear chamber and a very low resonance. Very wide bandwidth and very low distortion. It's obviously a close relative to the 6600. If you need a small tweeter that can cross over very low, this may be the one, though at a high price. If crossing over higher however, there may be a more suitable tweeter at a lower price. Tested November 2008.
Hiquphon OW4 ($132 ea) - Similar performance to the OW1 (see below) but with a higher SPL. A peak in the F5 at 3.5k could lead to the impression of false detail. Works surprisingly low for a 3/4" dome, LR4 @ 2kHz is no problem. Tested March 2006.
Scan-Speak 9500 ($132) - Slight "twin peaks" in the impedance curve and the related ragged low end rolloff. Response is very smooth otherwise. Nice distortion numbers except for a slightly high F4 at 2kHz. Decent metal faceplate. Tested April 2005.
Hiquphon OW1 ($110 ea) - Popular and expensive 3/4" dome. Near perfect response curve and equally perfect off axis curve. The CSD stops on a dime. On the negative side, HD is merely average. Cleaner than the OW4 above 3kHz, but tall order HD peaking at 2kHz. Crossing over higher is better for the OW1. Tested March 2006.
Seas T25CF001 ($103) - Extremely smooth response and excellent build quality. Decent harmonic distortion above 2kHz. Very good even order HD and average odd order HD. Slightly higher tall order harmonics than the best in this group. Slightly expensive for what you get. Tested April 2006.
Seas 27TTFNCGW ($89) - This is a titanium dome tweeter with a ring neo magnet, rather than the more common slug magnet in most neo tweeters. The rear chamber is extruded aluminum that doubles as a heat sink. Performance is good but not compared to the cheaper standard 27 series. There is a shelf in the response between 2 and 3kHz likely due to an internal reflection from the back of the chamber, and harmonic distortion is a bit higher than the 27TBFCG. Tested July 2007.
Peerless 810921 ($78) - Also known as the new HDS tweeter. Peerless finally creates a world class tweeter to compete with the best from Seas and Scan-Speak. Very low distortion levels and smooth, controllable response. Minor FR dip at 6.5kHz. Beautiful cast metal frame. Reasonable price. There's not much to complain about here and this is one of the best in the group. Tested June 2006.
Seas 27TBCDGB-DXT ($52) - A unique small waveguide version of the respected 27TBFCG tweeter. No ferrofluid results in a slightly ragged and peaky impedance curve. Distortion is low and response is smooth. 15 and 30 degree off axis response is impressive. While I could hope for a larger waveguide version, this is an excellent tweeter. Off axis response curves available. Tested March 2008.
Dayton RS28A4 ($49) - An Usher tweeter custom made for Parts Express. Ruler flat frequency response from 1 to 12kHz with a 5dB dip at 17kHz. Excellent CSD, Highish F3 HD below 2 kHz. Average HD above 2kHz. Nice build quality and metal faceplate. I tested 8 of these, and there was a consistency problem. Tested May 2005
Seas 29TAFW ($49) - This is the metal dome counterpart to the 29TFFW below. Similar performance though slightly cleaner HD and a bit more frequency response variance in the top octave. More extended and clean low end make this suitable for low or shallow crossover usage. Nice mid priced tweeter. Tested December 2007.
Vifa XT25 ($48) - Smoothest and most extended response curve in the group, and resulting CSD is excellent. Good tall order HD above 2kHx, but average 2nd order HD. Poor HD levels of all types below 2kHz, even considering the extended low end. It may have a 500 Hz Fs, but don't think about crossing it below 2kHz LR4 or 2.5kHz LR2. Off axis response curves available. Tested January 2006.
Seas 29TFFW ($49) - Highish Fs, steep low end rolloff. Smooth response with 2dB droop on top end. Good CSD. Average 2nd order HD, increasing 3rd order at 1.2kHz. Best crossed over LR4 1.5kHz or above. Nice thick flange design. Very efficient. Tested August 2005.
Seas 27TBFCG ($43) - 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. Ultrasonic breakup node at 26.5Khz. The hexagrid cover is ugly. Off axis response curves available. Tested April 2005.
Seas 27TDFC ($40) - Exactly the same as the TBFCG, but with a fabric dome. Slightly rising top end response but overall very smooth. No ugly hexagrid. Similar to the old 27TFFC, but with a polymer surround and slightly cleaner performance. Tested April 2005.
Vifa D26NC55 ($37) - Very smooth response with mild tilt down of a couple dB over it's range. Near perfect CSD without no high frequency garbage. *Very* low HD above 2.5kHz with a mild 3rd order peak at 1.6kHz. Almost a complete lack of tall order HD products. Well built small flange neo with heat sink and excellent internal construction. Off axis response curves available. Old/Other tests available. Tested December 2007.
Seas 22TAFG ($34) - Very smooth response with 3dB rise at 20Khz which is flat when 15 deg off axis. Breakup node at a very high frequency. Average Fs for a 3/4" in this class. High HD below 2kHz, best if crossed over 2.5kHz LR4 or 3kHz LR2. Another ugly hexagrid cover. Tested August 2005.
Seas 27TDF ($33) - Near flat line response through this tweeter's entire bandwidth. Similar to the "C" verion but slightly cheaper and without the rear chamber. Without the chamber, this tweeter has more ouput between 1 and 2kHz, a higher Fs and a higher Qts, but can operate just as low with a crossover that deals with the sharper impedance peak. Tested November 2008.
Vifa XT25SC50 ($33) - Smooth response except for a mild peak at 4kHz with a small bit of ringing in the CSD. Decent harmonic distortion performance for neo tweeters in this group. Recommend 2.5kHz LR4 0r 3kHz LR2 xover points. Performs well but not equal to it's larger brother. Tested April 2006.
Morel MDT20 ($33) - (discontinued) Poor 2nd order harmonic distortion and a ragged response curve in the top two octaves. Regardless, this would still sound pretty good crossed at LR4 2khz or higher. High intermodulation distortion. (not shown) Tested April 2005.
Seas 27TAFNCG ($32) - Smooth response with a mild Qts bump at the bottom. Multi-chamber neo magnet allows lower Fs than many other neo tweeters. Good but not great HD, but should have no problem crossing over at 2kHz. Small front/surface mount design. Tested May 2006.
Seas 27TFFNCG ($32) - Smooth response with a mild Qts bump at the bottom. Mild response droop above 15kHz. Essentially the same as the aluminim dome version above, but with a fabric dome and a hexagrid cover. Small front/surface mount design. Tested March 2007.
Seas 27TFFNC-CG ($32) - The tweeter is exactly the same as the 27TFFNCG, but with a flange that is a copy of the popular D26NC55. This Seas is a decent tweeter, but the Vifa is generally a better performer. Tested March 2008.
Vifa DX25 ($31) - Smooth and extended response at both ends with mild 3dB depression in the whole top octave. Low Fs for a tweeter with no rear chamber. Good CSD. Excellent 2nd order HD above 1.8kHz, very bad 2nd order HD below 1Khz. Cross over 1.8kHz LR4 or 2.5kHz LR2. Very efficient with high power handling. Tested August 2005.
Vifa D27SG15 ($28) - (discontinued) Shielded full size tweeter in the bunch. Relatively smooth and extended response. Small 3rd order HD peak at 1.6kHz. Rising 2nd order HD below 1.5khz. Cross over steep to avoid these issues. Slightly high 3rd order HD at 5kHz, bordeline audible. D27TG05 and D27TG15 perform identically. Tested April 2005.
Seas 25TFFN ($27) - Strange tweeter. Drooping response at both ends but smooth. Decent, but high 3rd order HD limits crossover point to anywhere above 4kHz. Shaped kind of like the old cheap Audax polymers. Can be surface mounted with no ill effects. Tested April 2005.
SB Acoustics SB25STC ($25) - This is a low cost tweeter with excellent build quality but a few issues that prevent it from being the best at this price. Harmonic distortion is good but not great, and the response curve is rough with internal reflections causing an issue at 3.5 kHz. Tested March 2008.
Tangband 25-1414 ($24) - (discontinued) Performs almost the same as the cheaper fabric 25-1166 version listed below, with the same 10kHz depression, slightly below average HD performance and a little more sensitivity. Tested February 2007.
Dayton DC28F-8 ($20) - The popular "silkie" returns with a redsign and hopefully some consistency. Response is relatively smooth but harmonic distortion is average to poor. It will work crossed LR4 at 2kHz or higher. Not the best value in the under $20 range. Only 3 screws on a flange this big is a bad idea. Tested February 2006.
Dayton ND28F ($19) - This is a nice performing small flange neo tweeter. The harmonic distortion is relatively clean for this price range and the tweeter should be able to handle 2 kHz LR4 at reasonable levels. Sensitivity is low. The response curve looks good except for a high Qts low end bump that will need to be addressed in the crossover. Tested December 2007.
Tangband 25-1166 ($19) - Relatively smooth low end rolloff for a neo tweeter. High F3 and F5 limit use down to 3Khz with a steep crossover. Slightly drooping response around 10kHz probably contributes to a laid back sound. Sticky coating = a furry dust covered dome in a year. Tested April 2005.
North D2506-S ($18) - (discontinued) High value tweeter with relatively good performance for the price. Sold in "matched pairs" a point which is of questionable value. Can easily cross over as low as 1600 Hz LR4. Ovarall, one of the best at this price point. Tested March 2006.
Hi-Vi TN28 ($17) - 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.
Vifa DQ25SC16-04 ($16) - A very nice performing low cost tweeter. In fact it's only downfall is a slightly rough top end that's not likely to be audible. Very clean operation on the low end, particularly for a small neo tweeter. It's a value leader in this price range. Tested May 2008.
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. Old/Other tests available. Tested February 2007.
Vifa BC25SC06-04 ($12) - This is a low cost fabric dome tweeter with mild horn loading. Very nice harmonic distortion but a mild internal reflection causes a hiccup in the response curve at 4kHz. Response is otherwise smooth. Good value. Tested May 2008.
Aura NT1-204-8D ($12) - Small and inexpensive rear mount dome tweeter with pure titanium dome and a coated fabric surround. Smooth response and good harmonic distortion above 3Khz. Exact same rear mount flange as the Dayton ND20. Great value and a good mate to a small woofer or mid. Tested March 2007.
Hi-Vi K1 ($12) - 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. Tested September 2005.
Goldwood GT-525 ($10) - This is a horrible tweeter on all counts, just stay away. It has a ragged low end response and piercing harmonic distortion. Low build quality tops it off. Tested April 2008.
Goldwood GT-520 ($10) - This appears to be a horn loaded version of the GT-525. Harmonic distortion is improved over the 520, but now the response curve is completely unworkable. Poor performance overall. Tested April 2008.
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. Tested February 2007.
Hi-Vi TN25 ($9) - This is a neo magnet tweeter with a rear chamber. Flow restriction between the chambers causes two impedance peaks and a dip at 500 Hz. Harmonic distortion is generally too high across the board, and there are cleaner options in the price range. Tested April 2008.
Dayton ND20FB ($8) - Very smooth, usable response. Nifty rear mount design. Good distortion performance above 3.5kHz. Super small and super cheap but definitely usable. Note that this "F" version has ferrofluid. Old/Other tests available. Off axis response curves available. Tested April 2008.
Dayton ND20FA ($8) - Like above, but front mount press fit. Slightly different dome material and slightly more peaking on the top end. Tested surface mounted, a likely installation for this tweeter. Note that this "F" version has ferrofluid. Old/Other tests available. Tested June 2008.
Dayton ND16FA ($8) - Very nice "super-mini" dome 5/8" diameter. Press fits into an easily drilled 1-1/4" hole. Works well from 3500 Hz and up, making it a possible mate with small woofers or mids. Big value for small dollars. Tested February 2007.
Hi-Vi T20-8 ($5) - The cheapest tweeter in this test is worth the money with some limitations. The top octave response is rough but good enough. A smooth low end makes for an easy crossover but harmonic distortion limits useful low end range to 4 kHz. Off axis response curves available. Tested April 2008.
Hi-Vi T20-4 ($5) - 4 ohm version of the T20 above. Very similar, but 3 dB more sensitivity and a DCR of 3.3 ohms. Tested May 2008.
http://www.zaphaudio.com/tweetermishmash/ 感谢楼主，还有个小小请求：可以翻译一下吗？ 你需要哪个,别说所有的!!!!!! 一直不明白 Vifa XT25 跟 XT25SC50有什么区别:Q
XT25
XT25 XT25SC50a mild peak at 4kHz with a small bit of ringing in the CSD. XT25比XT25SC50强。有人说XT25声音暗，问题估计就在这里，XT25SC50性能很一般。一个48$,一个33$，真是一分钱一分货。 谢谢meridian的瀑布图，只是水平太菜，看不明白，能否详解一下瀑布图的读法？
另：
这失真图中的几条曲线分别怎么定义？谢谢

http://bbs.hifidiy.net/viewthread.php?tid=125660&highlight=%C6%D9%B2%BC%CD%BC Scan-Speak 7000 ($398) -这个本质上是XT25的高端版本。 表现在所有区域是小的提高。 修造质量是与不会翘曲的厚实的金属耳轮缘的顶面山谷。 不幸地，价格是可笑的，并且价值是低的。 测试2008年3月。
Seas Crescendo($336) -旗舰高音扬声器，非常昂贵。 巨大修造质量和神色，视觉上匹配Nextel绘了低音扬声器。 当它更好比千年时执行一点，它仍然是仅仅平均在线性和非线性畸变，并且价格是可笑的。 测试2007年2月。
Scan-Speak 7100 ($285) -从扫描讲一超离频的末端高音扬声器，一个逐步减低在从7000个圆环幅射器的价格。 外表上，圆顶类似6600，但是与一个不同的磁铁结构和通风口一起有在阻止的涂层上的某一区别和前。 比6600敏感。 非常独到干净的低阶和低谐波畸变。 在顶面八音度有一个小的褴褛反应，但是整体巨大表现。 注： 这是-01版本。 测试2007年2月。
Accuton C23-6 ($262) -非常昂贵的陶瓷圆顶高音扬声器。 有一点褴褛反应和相关能量储备发布在4kHz。 温和的顶面八音度耷拉。 优秀二次HD。 在3Khz之上的例外苛求HD，但是高第3顺序下面HD。 如果您能修理在天桥的响应曲线，这通常是一台好高音扬声器。 然而有好在这个小组和为较少金钱。 测试2005年9月。
Seas Millennium($224) -明确和普遍的高端高音扬声器。 正派二次HD，辜负的第3顺序HD。 在完善的响应曲线附近。 实际上用一个特别和可认识的铜圆环修造的凹槽。 重，厚实的轮缘。 注意有些伙计提及了在反应的一个峰顶在12kHz。 然而不在我的。 测试2005年4月。
Scan-Speak6600 ($220)亦称- “AirCirc”从它是独特的磁铁和后方房间设计。 这个高音扬声器有非常低非线性畸变。 它在若干地方采取了XT25的一些个设计元素并且改善。 低价的畸变是更好的，并且轴反应是离一个1个”圆顶的法线较近。 对此的唯一的阴性多年来是在顶面八音度反应的一个小垂度，高价和某一生产变化。 老或其他测试可利用。 测试2008年5月。
Scan-Speak 602010 ($199) -这是将被发布的第一台高音扬声器在扫瞄之下加了反光板线。 它有一个后方房间和非常低共鸣的一台小轮缘新磁铁高音扬声器。 非常宽的带宽和非常低畸变。 它明显地是相对6600。 如果您需要可能横渡非常低的一台小高音扬声器，这也许是那个，虽则以一个高价。 然而如果横渡在更高，也许有一台更加适当的高音扬声器以低价。 测试2008年11月。
Hiquphon OW4 ($132 ea) -相似的表现对OW1 (如下所示)，但是有更高的简单程序设计语言。 在F5的一个峰顶在3.5k能导致错误细节印象。 工作惊奇地低为3/4 "圆顶， 分频在2kHz是没有问题。 测试2006年3月。
Scan-Speak 9500 ($132) -轻视“双胞胎峰顶”在阻抗曲线和相关褴褛低价的复制出。 反应否则是非常光滑的。 好的畸变编号除了有一点高F4在2kHz。 正派金属花盘。 测试2005年4月。
Hiquphon OW1 ($110 ea) -普遍和昂贵的3/4 "圆顶。 在完善的响应曲线附近和平等地完善轴曲线。 在一角钱的CSD中止。 在消极边， HD是仅仅平均。 擦净剂比在3kHz之上的OW4，但是锐化在2kHz的苛求HD。 横渡在更高为OW1是好。 测试2006年3月。
Seas T25CF001 ($103) -极端光滑的反应和优秀修造质量。 在2kHz之上的正派谐波畸变。 非常好顺序HD和甚而平均奇怪的顺序HD。 有一点更高苛求泛音比在这个小组的最好。 有一点昂贵为什么您得到。 测试2006年4月。
Seas 27TTFNCGW ($89) -这是与圆环新磁铁的钛圆顶高音扬声器，而不是在多数新高音扬声器的更加共同的子弹磁铁。 后方房间是被挤压的铝那双作为吸热器。 表现是好，但是与更加便宜的标准没比较27系列。 可能有在反应的一个架子在2和3kHz之间由于内部反射从房间的后面，并且谐波畸变高于27TBFCG是。 测试2007年7月。
Peerless 810921 ($78)亦称-新的HDS高音扬声器。 绝世最后创造一台国际水平的高音扬声器与从海的最好竞争和扫描讲话。 非常低畸变水平和光滑，可控制的反应。 在6.5kHz的较小FR垂度。 美好的塑象金属框架。 合理的价格。 没有抱怨的这里，并且这是一个在小组的最好。 测试2006年6月。
Seas 27TBCDGB-DXT ($52) -受尊敬的27TBFCG高音扬声器的一个独特的小波导版本。 ferrofluid不导致有一点褴褛和有峰的阻抗曲线。 畸变是低的，并且反应是光滑的。 轴反应的15和30度是印象深刻的。 当我可能盼望一个更大的波导版本时，这是一台优秀高音扬声器。 轴可利用的响应曲线。 测试2008年3月。 软件翻译的 原帖由 lakerblue 于 2008-12-20 16:53 发表 http://bbs.hifidiy.net/images/common/back.gif
