偶然看到国外最火的diyaudio的帖子里，德国KAISER 的当家人Rainer Weber 对70-20XR-AM 与ACCUTON D20,30 钻石高音的PK 评价记录。

from my experience the RAAL ribbon outperforms the A Capella ionic tweeter, especially when an amourphous core is used (possible as option from RAAL).
I compared the RAAL also with Accuton Diamond tweeter (D20 and D30) and Scan Speak dome and ringradiators.

The RAAL (70-20 XR) is by far the best sounding tweeter.

RAAL高音有意，请报价
