low sensitivity are really hard to drive and require high power output amp to drive. 4 ohms easy to drive but difficult to drive well since amp demand (current) will be much higher to g ...

do u mean 4 ohm only consume more power (current) to get a same workdone by 8ohm? 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.{:6_184:} 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。 搭單一問：

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{:1_342:} 當然這個並不是單一因素{:1_245:} 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,...

明曬.總知部amp 夠力推為首要條件 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{:1_245:}
