咁多廠出過, ohm 數又唔同, 線路零件數值未必同, 點呢?

I am afraid that is totally untrue.

LS3/5A was created because KEF no longer made the driver B110/A6362 which is what the LS3/5 was designed for.

It was for exactly the same reason why the LS3/5A has to change to the 11 ohm version as KEF changed the B110 again in 1976.

And not because 15 ohm LS3/5A was a failed product.

Contrary to what some believed, the LS3/5 was not just a prototype. It was put into operational use and formally documented by BBC:
www.bbceng.info/EDI%20Sheets/10055_1.pdf

In fact, it was so successful that BBC wants to have it mass produced by commercial manufacturers such as Rogers. And Rogers was first invited to make the LS3/5 and not LS3/5A.

When KEF stopped production of B110/A6362, Rogers got stuck and has to ask BBC to modify the spec to use B110/SP1003 instead, which became LS3/5A.

No, it is as rare as Kingswood Warren LS3/5A i.e. LS3/5A made by BBC itself.

金麟豈是池中物,
一遇風雲便化龍,
九霄龍吟驚天變,
風雲際會淺水游。
成也風雲,敗也風雲。
毋用強求,一切隨緣。

成和敗,都喺分音器所為

這幾年聽 Goodmans 80 和 西電 755A 之類的全音喇叭,無分音器的音染。快捷,真實,明朗。

用得分音器,註定要享受分音器的音染。好比食醬油雞, 不是說醬油雞不好味...而是缺少了原汁原味的雞味。後續再講究用哪牌子的醬油去煮,是後話了。

個人在80年代初開始玩3/5a(前后玩過3對),再用電分加超低音,到90代迷上號角全頻,根本沒有興趣聽分頻器喇叭
我算是中了全頻毒,想回頭聽有分音器喇叭,實在有一些困難。

話雖 彈下 3/5 仔的分音

但3/5仔可做出的離箱感,定位準確度,確是一絕。我玩過~20款喇叭,還未有一對比得上3/5仔
可能是拜謝佢密封式的設計

"""ls3/5 分音器線路圖"""

這是...16Ohm的嗎?



"""...it was so successful that BBC wants to have it mass produced by commercial manufacturers such as Roger..."""

If so, why KEF would have decided to terminate the production of
B110/A6362 (and eventually the B110/SP1003 as well).

-----------------------------------------------------

KEF couldn't care less what BBC wanted. It was only interested to reduce production cost and its own speakers were already designed for the later KEF driver model.

It was for the same reason why earlier tubes of the same model from the same manufacturer always sound better than later production.
