真係好多喇叭，可否post 果部car amp 睇下{:1_347:}

用car amp 做home theater，OK 嗎？

咁細地方,用咁多喇叭,真係可以發揮到嗎？
7.1 其實對你黎講都好夠！

2 main issues:

1. power supply - 12V is usually required by car amps. a high quality step down transformer does not come cheap.
2. ohms per channel - for car amps, usually 2 - 4 ohms per channel. However, most home speakers are 8 ohms. Hence, it will be difficult for a car amp to drive home speakers efficiently.

Also note: for the very limited space for this case, more does not mean it is better. Positioning of the speakers are definitely an issue. 5.1 will perform better than the existing "11.2". This will avoid phase cancellation.

多謝c兄們指教{:6_183:}
不過小弟還有自己想法要c兄們指敎{:6_240:}
Av amp 由最初5.1到現在11.2是不是廠家騙我們買新機?
我想應該不是吧{:6_192:} 因為我用耳貼在上置喇叭聽到的聲音跟前置聲昰不同的。
而且就算用5.1都會有phase cancellation,房裹面又勁多傢私雜物,所以玩多聲道對抗不規則反射環景
試過又覺0K喎{:6_238:} 唔信試下啦{:6_222:}
