有事請求助

Martin,

1. Most of the "good" crossover  capacitor is high voltage in the market. Say > 400V. The size is bigger of your photo one.

2. We can help you to measure the value of your inductor. Air core inductor size is 4X bigger than "Iron" core inductor.

3. Resistor, it is easy to solve than inductor and capacitor.

4. Suggest you modify at below: (Most important, and more efficiency)

Woofer :
4.5mH --> Air Core type.
18uF capacitor

Middle Range (Mode)
3.3uF x 3pcs
3.3R
12uF.

KK.HO

Suggest you WIRE WRAP and don't use that PCB.

Can you post the photo here of your speaker?

老友，我想改口供:

先換內部接線，用sound from heaven (鴨記LH有售)

高音中音電感己是空氣芯，不用換

低音那個是用磁芯那個，換掉吧，不過好然貴

高音電容也換吧但不要瞓身, 它已比低音部份notch filter 用的要好。

電阻換然哂佢啦，影響超大。

高音有一隻保護零件(以後吾提得果四個英文字)，請直通它，(如果閣下擴音机真的不出DC)。

記住攪之前量度一下frequency response.
用儀器才知邊度吾掂。
我另一篇文有教，自己揾揾

另外你還要多謝MODI，佢係我師父
我係量產型一個，通街都係


吾明再問。

Modi,

低音用電感是計 (H) Henry. 及線徑.

留意附件.

吾好教壞細路.

梗硬用幼線徑線圈衹會 Saturation, or 內阻增大

It is no problem, but need to good soldering of wire.
Make sure Left and Right Channel are equal length of each wire. Include (+) and (-)

不用怕，你分音器輸入有電容乜野DC都block 哂。

大佬，叫我做KK苦主便可以，勿叫恩師。

1.你音箱大，分音器比我會用三塊底板。
2.到鴨記華X買鍍銀底板(共六塊，有大有細)
3.擺好型狀，用鎅刀切去不要的銀
4.焊上零件收工。

大佬，喇叭端子輸入焊三紅三黑線，各自去各音道分音。
分音輸出接喇叭。

如果你輸入係bi-wire, Tri-wire. 更好。

可吾可以映個屎弗睇下。看看有幾多個輸入。

吾係你個紙筆。

Ai.......soldering 3 pair of wire la....
