Audio gear fans dream WE555 .....音頻設備球迷的夢想 WE-555

WE Acoustic 555 mid range horn driver.
Specifications:
Frequency response: 100~5,000Hz Field driver


The early Western Electric theater loudspeakers were basically one-way designs, consisting of a large curved ("snail shaped") exponential horn. The Western Electric model 555 driver was used with these horns, and frequency response was band-limited to the range from about 100 Hz to 5000 Hz. In time, Western Electric added a high frequency unit as well as a set of low frequency 18-inch drivers to augment the response of these systems. Jensen 18-inch woofers in a large open-back baffle were coupled with a horn tweeter, which extended the response of the basic system downward to about 50 Hz and upward to about 8 kHz. These modifications to the basic Western Electric one-way system were introduced in 1931 and represented a major step forward in exhibition sound quality.

WE555 need add 15A horn co-work then reach to 100Hz.
WE15A horn 看起來很小其實不然 .......從日本另一燒友的設置WE15A就大的有些嚇人.
搞起來老婆會把你趕出去



再看日本人對555做了甚麼.
在日本真真的第一顆555 是YL  Acoustic 555下面著個.

YL  Acoustic 555 mid range horn driver.
Specifications:
Frequency response: 100~5,000Hz  Alnico
號稱日本西電 555 完全一致響應.


爾後...


連超強力型都出來了.......真是輸人不輸陣.

Y L Acoustic 550N mid range horn driver.
Specifications:
Frequency response: 100~6,000Hz
Independence: 16 ohms
Max power handle: 20W.....強力型.

日本西電.... 不應是YL-555 響應要到100Hz 附近也需有超超大號角的.
接下來看紅框內諸元.....也沒在輸的.

Finish!


羅老 sorry 轉貼 Look-T blog...
點火....一道紫色光噴出，送上音樂一陣奇妙的聲音在耳邊響起，調好音壓比例，哇.....小提琴的嚓弦聲絲絲入扣，整個音場空氣感十足，這才算是超高音，以我的經驗所有有型體的喇叭發出的氣聲，音質和擴散性真實感都跟不上離子高音，真實感尤其重要，我們多數的音響都只能說好聽，認真說來就缺這種如臨現場的真實感！

另羅老 全新架構300B SE
羅老........十年對管機和輸出變壓器的浸盈研究 ...... 的感性論述.
這新架構的機器背景特別乾淨，一開始有點尖銳，開機一兩小時就相當好聽，現在5分鐘我就感覺到位了，所有的樂器像是跳出來似的，非常的透明立體，單端管機的霧霧感都沒了，再說這樣的霧霧感覺可是花了10年才解決，這也是這機器最大特色。

敝人覺得.....對管機有鐘愛的同好, 一輩子對聲音尋尋覓覓的朋友, 別忘了這個...有可能一解您的宿願.
