想配个家庭影院,看到FS 有2个在打折,没有经验,给点建议。
我只是入门级的水平,本来看中BB的这个 SONY的 http://www.bestbuy.ca/en-CA/product/...d50a21f5fben02 在这里读了些帖子扫盲一下后,觉得至少应该买Receiver-Based All-In-One Systems, 价格不要超1500. 这3个如何? http://www.futureshop.ca/en-CA/produ...c80a1e5en02。 http://www.bestbuy.ca/en-CA/product/...b5a4049ca5en02 http://www.bestbuy.ca/en-CA/product/...4f743aeb17en02 |

I usually do window-shopping in nearby BB and FS during lunch hour. From what I have listened to the receiver/speaker combo on the shelf, they lack the power to push floor-stander speakers, even worse when you add in surround + center because the small power supply is being shared to drive all connected speakers. From a volume scale of -80db (less volume) to 0 db (more volume), I need to turn it to at least -10db for acceptable volume. One way to nail this is to look at the specification. When it lists a total output of 700w but the total power consumption is only 350w, it is not right. When you have five speakers connected you can only get 70w per channel average. Not even 70w/channel considering there is overhead in powering additional circuits. 70w for one average speaker sounds like a lot but the fact is not every watt is produced equally across different brand of amplifiers. Some are strong, some are weak. Not sure what is the size of your listening area, but if you intend to have more speakers, the receiver needs some real power to drive them. For example, a pair of floor-standers with two woofers each needs bigger power to drive than a pair of bookshelf with a single woofer each. Some receivers do have additional outputs called pre-out. What they do is to route the line signal to a separate amplifier to provide additional power for speakers. If you intend only to have small speakers (satellite) and will not upgrade to a better one, then an average AV receiver without pre-out is fine. |

第2个还可以,RECEIVER是7.1的,可加2小喇叭变成7.1。 第3个实际是2.1系统,还要加3喇叭才是5.1,不容易配套,还要加钱。 最后一个最不值。 店里配的不一定好,最好自己配,RECEIVER和喇叭分开买。也经常有特价,关键要有耐心。1500可以买到不错的了。 |
