你我聽的 TAD 是這阿姨做的!

你我聽的 TAD 是這阿姨做的!


即使揚聲器已關閉生產線自1966年以來,幾乎沒有任何媒體被邀請參觀設施。
下定決心,學習更多關於先鋒 TAD 難以捉摸...超級單體,
家庭影院月刊的編輯史蒂夫 最終獲得獨家訪問,並跋涉到Tohoku 工廠在 Tendo近郊 ,
來看TAD超級單體如何開發問世。
在大門之內,我們發現了一個小的團隊,致力於使這些龐大的箱子發聲。
事實上,她們手工量產製作的僅僅是極少數的揚聲器,但其中的音圈繞製和音圈裝配,鈹震膜組裝超過 20年。
揚聲器部門經理鈴木隆說:這是一個特別的工作。
甚至在先鋒TAD,很少人知道如何製造這揚聲器。鈴木隆解釋說:1990 已設計組裝和測試TAD的揚聲器,一個揚聲器單體有相當數量的特性和響應要測試,但工作是值得的。
我敢說,世界各地的專業音響工程師會同意我的說法。
其實,TAD生產線僅僅是Tohoku 廠的一小部分。開始是為 先鋒的 Carrozeria 汽車用揚聲器,計組裝和測試揚聲器而生產設製,而後研發團隊部分從 OELD 顯示部門整併,轉移在TAD 揚聲器一切技術創新後開始組裝和測試。
並以某種方式恰當,這影響力仍然影響對品牌前瞻性思維的高科技;接近該廠是東北先鋒的自動樂器博物館,令人印象深刻的,廣泛收集古董音樂盒,可以追溯到19世紀。
熱情的先鋒的創始人 Nozomu 松本說:這些都是複雜的工程傑作 - 就像TAD的R1S。


十多年來,三重鈴木一直組裝和測試TAD的揚聲器。她的一部分小團隊,負責為一些世界上最大的Hi - Fi組裝和測試套件....從製樣到量產TAD 1600-系列都經她手摸過!
1. Here the voice coil – an aluminium ribbon wire insulated in aluminum film – is attached to a TD-2001 high-frequency driver.
The ribbon is hand-wound onto a bobbin formed from a high-polymer compound that's heat resistance up to 400ºC,
providing a tolerance for high-energy input levels.


2. After attaching the voice coil to the bobbin, any excess glue is carefully wiped away…


3. Here, a voice coil wire is soldered to the lead wire on a TAD TL-1603 low frequency speaker.
The TL-1603 is designed to work with a maximum input of 500W.


4. A pure beryllium diaphragm is used to make the TD-2001 driver.
It's designed to give an extremely flat frequency response with outstanding transient response and high-fidelity imaging.
 Here, the voice coil assembly goes through final adjustment.


5. Every component in a TAD Reference One speaker has been optimized for performance,
making the models a favorite of sound engineers worldwide...圓狀物是compression driver 驅動器震膜.



6. A voice coil is attached to a TD-4001 rear -compression driver and cleaned.
One of the world's most lauded speaker designs, it can deliver stunning audio clarity.


這真是關著門DIY到底!

走過咖啡店早年歲月

咖啡店從無到有... 從有到無... 歲月的流逝 ,剩下的祇有記憶.

從無到有--- 舊店設立.
從有到無--- 拔營....牧咖啡的咖啡人.....移址, 啡客...........的遷徙.

咖啡店=咖啡+音樂

咖啡=日式咖啡+美式咖啡
日式咖啡=日式單品+日式花式咖啡
美式咖啡=美式單品+美式花式咖啡
.........."請不要找茶".

音樂=古典音樂+真空管
