DIY重低音線

我想DIY條重低音線，請問各網友高手有乜抵用又吾太貴既散線推介？邊度買？幾$?
又想知其實重低音線同一般音頻線設計上是否大不同？將音頻線或用75歐姆訊號線做重低音線用，效果是否差D？
重低音線係米單支會好過散芯線？粗線芯係米又會好D?
多謝各位指教！

What is your budget ($xxx / Feet)

又想知其實重低音線同一般音頻線設計上是否大不同？將音頻線或用75歐姆訊號線做重低音線用，效果是否差D？

75 ohm major use in antenna application.
I think you are looking for normal coaxial cable for audio use.

重低音線係米單支會好過散芯線？粗線芯係米又會好D?

Depends on characteristics of impedance.

多謝各位指教！
No Thanks


又係問答時間

1. What is Characterisic of impedance ?
2. If wrong matching, what happen ?
3. How to measure this impedance over on the cable ? What kind of equipment need to use ?
4. PCB also have characteristic of impedance. What is it ?

Will give the ans at coming SAT.

Thank you kk sir then we got more thing to learn.... :wink:

not really know the charcteristic impedance, only know 2 wire parallel, even not connected, if voltage apply in it will have characteristic impedance
then a lot of furmula to describe this.... just know that the characteristic impedance is low with material with low resistant(high conductivity)

Thank you Sir.
My budget  near $30/feet, 我見鴨記有舖賣 Monster Interlink401 audio cable, 一條線內有兩獨立線芯及網，適合用做重低音線否？
但又想知鴨記呢D舖賣既Monster cable 係米真野？

Thanks to KK Sir.
