同軸陣列高音唷! 爽度100。
看一下低音紙盆，深度曲度還真特別!
↑↑↑
音箱弄成這樣，也很不錯!
這空間應該有10坪；很多國外玩家，幾乎都玩二音路，同軸整合實在不錯，美觀又大方
1輩子有這麼長；慢慢玩；慢慢玩!
↑↑↑
低布那低音箱的設計，我認為這是最棒的低音箱設計
二單體，面對面；下次改玩這種低音箱。
這系統，應該是電分系統。
↑↑↑
上面那EV號角，是我最愛最愛的號角之一，造型大方，很得體。 ㄏㄏ
底下低音音箱，也是號角；隧道越長，低音樂豐富。
↑↑↑
似乎是軍規由電容。規格1UF。用於分音器、旁路。
↑↑↑
這分音器風格，真像我，這樣很方便，我都用鱷魚夾。
↑↑↑
這級間盒，還真有風格。你也知道我是級間迷。
最近我也在為級間盒的造型再困擾!
前天還去買一個古典旋鈕哩!

哈哈哈，裝12吋低音，帳版系統。 這輩子別無所求，我只要這樣，靜靜地待一晚就好。
從下圖可看出精密線繞電阻, 是用鎳鉻電阻絲繞製而成, 結構要比一般薄膜電阻好. 電阻絲直接焊在引腳上. 不用端帽壓合, 接觸也最佳. 所以聲音當然會比較甜美細膩.
電阻中最甜聲的就是精密繞線電阻, 為甚麼搭棚好過PC板, 因為音樂的細微信號經過好的機內線和完全熔合的焊點,有如經過平坦的高速公路,平順而細滑. PC板就不一樣了,先是鍍的銅箔導電性就差一些,焊點也是需經過薄薄的焊錫才接通銅箔,有如經過橋樑不平的接縫. 經過粗躁的路面和一堆高低不平的接縫,好聲都被折磨光了. 精密繞線電阻 其引線和電阻體的接點是很講究的. 再加上電阻體本身就是電阻絲,比起一般金屬膜電阻好聲, 當然是必然的.有些人說線繞電阻含有電感成分, 會強化高頻, 其實剛好相反. 在較大阻值下, 繞線重重疊疊, 反而雜散電容的影響會大過電感. 所以用在回饋或屏極時, 不須再加補償電容.
Precision Wirewound Resistors
Wirewound resistors are generally classified as either “power wirewounds”
or “precision wirewounds.” Power wirewound resistors are
subject to greater changes in service and are not used where precision
performance is required; therefore, they are not considered in
this discussion.
The wirewound resistor is usually made by winding insulated resistance
wire of a specific diameter around a bobbin. Different wire
diameters, lengths, and alloys provide the desired resistance and
initial characteristics. Precision wirewound resistors have better ESD
stability and lower noise than thin or thick film resistors. Wirewounds
also have a lower TCR and better stability.
The initial tolerance of wirewound resistors can be as low as
・} 0.005 %. The TCR, which is the amount of resistance change with
each degree Centigrade change in temperature, can be as little as 3
ppm/°C typical; but for low resistance values, wirewounds are generally
in the region of 15 ppm/°C to 25 ppm/°C. Thermal noise is low,
and TCR tracking to ・} 2 ppm/°C over a limited temperature range is
possible.
