标题: 理想的两分频单元
近来坛里diy之风日盛,请各位兄弟推荐心目中最为理想的两分频单元型号,有请167大侠带头推荐

鲁菜、川菜、粤菜。。。。个人各位不一，恐怕选择也会有差异吧？！

都点名了，不好不说。那就说几句吧

1.汝之蜜糖，彼之砒霜。自己不喜欢的，不一定别人不喜欢，比如号角，比如硬膜高音等。

2.好单元是有客观依据的，各项T/S参数好是基础，如果在这基础上灵敏度比较高就更理想，如果主观听感好，那就是好上加好，这样的喇叭单元比较难得，比如T330D，比如AT等，比如ATC大磁钢馒头中音，都是参数好、灵敏度高、主观听感好的类型，属于极品中的典范。当然，他们的价格都不菲。

2.具体到做两分频，有两种思路，就是普通形式与号角音箱，它们的区别很大。
普通的形式，一般来说2分频的中低音单元最好不要大于7英寸，否则一来是对高音压力比较大（分频点低），二来是中低音单元对于中频的还原不理想；
另外就是号角音箱，因为中高音是压缩驱动器+号角，所以能分频在1k左右，这样中低音单元就可以选择10-15寸的纸盆布边喇叭。不过这种设计的源头是来自专业扩声系统，我觉得并不适合家庭hi-fi使用。

要看楼主的预算和声音追求了。两分频不可能面面俱到，尤其是低频。

如果我自己做两分频，在排除掉号角与平面喇叭后，会从下面这三个组合中选一个：

组合一：丹拿高音+AT低音
组合二：RAAL大铝带+AT低音
组合三：RAAL大铝带+ZELLATON低音

箱体构造参考这个：

如果有条件的话，箱体结构仿这个瑞士喇叭：

续6楼：
喇叭单元就用RAAL高音+ZELLATON低音，下图就是使用该低音的德国symphonic line两分频喇叭（这是一位广东烧友几年前发给我的图片）：

三分频就算有好的单元,想做出个出彩的音箱,太难了.

喜欢第一个组合，有很多成功案例。

作者: David 时间: 2011-1-9 14:53
AT单元型号众多，建议您向厂家咨询一下，将您的要求告诉厂家（越详细越具体越好），请他们特制一对喇叭多好啊。

大师,就普通形式吧,我想丹拿加at你一定会赞成,高音就定330了,at6.5寸烦请你推个具体形号,到时还需要你帮忙,先谢了.

三个方案，投资不同，功放搭配也不同。对于刚开始DIY的人来说，第一个组合的成功率高一些，第三个最具有挑战性。

千万别乱叫什么大狮的，你和我都会很别扭。
帮个忙什么的没问题，只要是我能力范围之内的

一、请看AT怎么说吧：
The Flexunits system was developed to fulfil individual data as desired, and we are able to meet even the most specific individual requirements – mechanical as well as electrical.

Fs, Vas and Qts can all be modified and the coil former can be made of either aluminium or Kapton. In special cases the cone material and suspensions can also be changed.

Gap height and coil length as well as diameter can be selected individually and the magnet size can be altered to fit the needed strength required.
For the less experienced customer, we have made a line of multipurpose drivers, represented by each size, from 4” mid-woofers through 15” subwoofers, enabling you to approach a project, the more conventional way. It is also possible to use one of the standard drivers as a raw model, and getting parameters changed in the direction you wish.
To specify your requirements please use our specification form. Remember that we can only work within the physical laws of nature.

二、下面是一鬼佬的推荐

Driver recommendations - Audio Technology

AudioTechnology is one of the world's most highly regarded manufacturers of ultimate quality drivers. Its Flex Units series is designed by Ejvind Skaaning, a founder of both Scan-Speak and Dynaudio. Flex Units are notable for all using some of the best motors in the business - comparable to the best that Lambda, TC Sounds, or Scan-Speak have to offer. The Xmax-to-Xsus ratio is typically 2.5:1 of greater. Audio Technology is perhaps the ultimate specialty woofer vendor, offering a limited range of standard drivers, although they do offer an almost unlimited range drivers built to order.

Note that the following list includes the entire standard Flex Unit line.
1. The 4H521306 is a 4" driver using an underhung motor suitable for both mid/bass and midrange duty. The FR is +/-2 dB from 100-5k Hz. One of my respondents wrote. "The Audio Technology 4" is absolutely outstanding, in every way.  It does require the best associated crossover components.  No evil habits, very transparent, clean, musical, timbral accuracy extraordinary, excellent dynamics, stays alive at low levels, worth every penny.  Easy to crossover also.  Does not have the high end peak that the [Madisound/Skaaning] SK130-308 does."  view response
2. The 5H521506 is a 5" driver suitable for both mid/bass and midrange duty. The FR is +/-3 dB from 100-4k Hz.  view response
3. The 6H521706 is a 6" driver suitable for both mid/bass and midrange duty. The FR is +/-2 dB from 90-4k Hz.  view response
4. The 8I522008 is an 8" woofer with smooth FR up to 2 kHz. Modeling suggests that it would work well in a TL enclosure.  view response
5. The 10A772510 is a 10" woofer with smooth FR up to 1 kHz. Modeling suggests that it would work well in a TL enclosure.  view response
6. The 12B772510 is a 12" woofer with smooth FR up to 1.5 kHz. Modeling suggests that it should maintain extremely high output into the 30's using a vented or PR enclosure. In a TL enclosure, it should reach the high-20's.  view response
7. The 15E1022510 is a 15" woofer with smooth FR up to 300 Hz. Modeling suggests that it should maintain extremely high output into the 30's using a vented or PR enclosure. In a TL enclosure, it should reach the high-20's.  view response
All Flex Units are among the most expensive drivers of their respective sizes on the market. The curves and numbers on all units are exceptional. Everyone who's ever seen and heard one agrees that they're magnificent in both design, craftsmanship, and audio quality. Certainly, the exceptional impedance curves reflect their extremely sophisticated and costly motor designs, which are capable of exceptionally low distortion. However, whether they're sufficiently wonderful to justify the price may be subject to debate, depending on your circumstances. Perhaps it will help if you consider them as instruments or works of art rather than drivers…

三、上面鬼佬的推荐只是针对标准型号的Flex Units单元，也就是AT所说的“For the less experienced customer, we have made a line of multipurpose drivers”。定制单元时，您可要求个性化的Fs, Vas和Qts数值，这些参数决定了音箱的型式（密闭、开孔）、容积、低频延伸、灵敏度等指标。具体选择什么型号的，尚需您自己拿主意。如欲省事，建议征求厂家或代理的意见。
