4 ohm 喇叭問題

babuwa

4 ohms easy to drive but difficult to drive well since amp demand (current) will be much higher to get better control on speaker.

low sensitivity are really hard to drive and require high power output amp to drive.

    do u mean 4 ohm only consume more power (current) to get a same workdone by 8ohm?

    Can't make such conclusion to compare 4 ohm and 8ohm speaker. To control the speaker better, normally 4 ohm speaker will draw more current from amp since impledence lower.

搭單一問：
如果部Amp祗支援 6-8 ohm，駁上 4 ohm喇叭，Amp 或喇叭會不會有損壞。

不會...我呢個佩答都用左5年喇..

打過比喻, 4 ohm等於水喉的直徑 (4 ohm比較粗, 8 ohm比較幼),  current等於水壓,  如果水壓足夠, 理論上, 水係水喉流動時比較暢通同水量會多些, 水射出來射遠的,  如果部amp的current係足夠勁,   你話 4 ohm 喇叭好定 8 ohm 喇叭好呢 當然這個並不是單一因素

    明曬.總知部amp 夠力推為首要條件

數據可以用來參考, 最後以耳聽為準
