又开始新的征途了，到时直接复刻一对😄

70-20XR分频点1800HZ（只串一个电容即可实现四阶分频，详情请看他家官网）。价格大概在7000到8000元一对，不过这个型号是不向个人（DIYer）出售的，您用谷歌去网上搜一搜吧。境外网上时常能看到有鬼佬出售，不过很快就被抢走。

World’s smallest form factor for a true ribbon of just 1.8 kHz cutoff frequency, reliable, able to handle a lot of power, sounding like it doesn’t exist... All that by using only one series capacitor as a complete L-R 4th order crossover at 1.8k, combining acoustical and electrical slopes, with minimum of added passive crossover components. Featuring three transformer taps for resistorless sensitivity adjustment, ribbon replacement kits, custom front plates, copper soldering posts...

All of it, makes it perfect for reaching new limits in high-end home stereo or multichannel and near-to-mid field studio monitoring applications.

It was developed according to the wishes of the most demanding manufacturers, that were looking for a quantum leap in true ribbon design.

The exact process of making it, will remain a well kept secret. Being different than anything else, including other RAAL models, 140-15D and 70-10, it is available only to manufacturers, only under previously signed Non Disclosure Agreement.

For further info on 70-20XR, please, send e-mail inquiry to info@raalribbon.com, stating your company data and your position in the company. If you wish, you can include a brief description of your project. You will receive a brief .PDF datasheet, with basic measurements and data. If you find it fit for for your project, we will proceed with signing Mutual NDA and after that you can receive paid samples.

带上我，我这次决定复刻你的音箱了，有了上次的经验，相信你会少走弯路。

折腾了这对音箱，用了RALL70-20XR非晶合金版，一年的时间，委托他人现在调试基本结束，就等重新做一个油漆。

个人以为，与ATD最搭的高音是RAAL，无论声音还是外观。玩好了RAAL，钻石不碰也罢。

RALL70－20高音素质真的不错，但分频点还是尽量在3000向上为好！

有意用同样的单元搭配diy一对 可以分享一下分频电路吗

可以分享，但我这个是低音推挽的，箱体制作你不可能完全用我这个方式，我的低音前面板是25MM的航空铝合金板，如果用MDF板那个厚度就不一样了，不是完全一样的箱体，一样的单元，分频就要从头再来，我的整个数据即使给你了也没有任何意义。

这是低音箱体中的金属结构件，你 否有条件完全这样做呢，面板25MM航空铝合金板，推挽箱是10MM厚的304不锈钢直径450MM的圆形结构件

这个也太强大了

中低用ATD，高音单元似乎还是钻石好。
