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.

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.

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.
醬知道有多大嗎.
