呢條喇叭線要點插

http://www.gotham.ch/en/index.php?section=docsys&cmd=12_details&id=73&bcsi_scan_5B9CA387A7EA8C1E=NTmcUbZLWAtp4GOpnu51PB8AAAD3D3sP&bcsi_scan_filename=index.php

想問下係咪就咁將3浸銅線 (i.e. 圖裡面的 3, 4 & 6) 扭埋一條呀?? 咁即係 一個喇叭要2條線, 一對喇叭要4條線??
如果係咁.... 咁中間果 d insulator 其實有咩用呀??

50150 GAC-SPK 2 x 2.5mm2 Quaxial speaker cable
GAC-SPK 2 x 2.5mm² (50150)Loudspeaker cables are transporting very high levels. In an ideal situation we want to have the lowest possible resistance between amplifier and speaker. In order to get closest to this figure, one should accommodate as much copper to the connector as possible to minimize the energy loss and the possible change of the sound performance of your system. Using a cable with a too small diameter can result the copper to transport the energy to its saturation, which will first decrease the level of high frequencies (cable gets warm or even hot) and affect your sound level and quality. Gotham currently offers two different speaker cable types which can be combined as single line, stereo line or Biphase lines and/or put together for lower resistance. All Gotham speaker cables are protected with ultra strong oil, heat and cold resistant polyurethan (PUR) jacket. The double layer copper strands for the outside line are built to keep a good flexibility and the stronger stranding of the center conductor (line) will keep the unwanted memory (bendings) to the minimum.

一條過中間d insulator係無用
不過唔係個個都3浸擰埋

廠方本身呢條線係行3+4一極,6係另一極,條線既設計據聞可將正負極干擾降低,但有d發燒友自己研發更好聲方法,將3,4,6全部當一極,如果甘做,基本上已經失去左呢條線既獨特設計,不如用佢地50040好過,重平d.不過兩款線線芯粗幼有唔同{:6_146:}

咁即係根原本的設計係 3+4扭埋當一極(紅色), 6自己一極 (當黑色), 一個喇叭只係需要一條線???

如果扭埋晒當一極, 同就咁搵條粗d既一線一芯有咩分別???{:6_141:}

如果扭埋晒當一極, 同就咁搵條粗d既一線一芯有咩分別???<===我未玩過唔敢講有咩分別,不過以一極計,線芯由2.5qmm行 double,應該電流量大左,量感會強左,其他應該分別不大(假設外皮同線芯物料相同情況下),比我會試下3+4做shielding獨立行一極.
