問到一些關於Beyerdynamic811, 911的資料, 大家參考一下

[albertyc]

由於小弟我對於越點的團夠方案也相當的有興趣, 但是在任何的耳機介紹網站上都找不到有關811, 911的資料, 就連beyerdynamic的網站上都沒有... 好齊心驅使之下, 我寫了E-mail到beyerdynamic的客戶服務部門, 他們還真的有出過811和911, 只不過後來停產了, 以下是原始郵件的內容, 工大家參考一下:

Thank you for your interest in beyerdynamic products.

Yes. Both the DT 811 and DT 911 are discontinued beyerdynamic headphones.
The DT 811 was an open, lightweight circumaural headphone with a wide
frequency response (5Hz-30kHz). They also employed Neodymium magnets for
superb transient response.

The DT 911 was very similar to the DT 811 - except that its frequency
response was from 5Hz-30kHz.

If you need any further information, please feel free to contact me again.

Subject: Hello, May I ask has Beyerdynamic ever made a 811 or 911
headphone??
Date: 3/21/01 2:08 PM

Hello,

May I ask a question about the headphones beyerdynamic ever made?? I found
a 811 or 911 headphone on a garage sale, I was interested about it, and I
came up here to find details about the headphone, but, there seems to be no
such headphone. Is that an old model that beyerdynamic stoped producing? And
why did beyerdynamic stoped producing that headphone? Can you please kindly
give me some information?

A poor student that can't offer brand new beyerdynamic 9xx series headphone.

對ㄚ... 我覺得他給我的回覆中有關811和911的頻率範圍好像打的怪怪的

根據我上次po的規格是差不多...

但是似乎聽起來又是另外一回事
