I'm new to the home theater setup and I received some equipment for Christmas gifts that I had no clue about. I got a Yamaha rx640 receiver and the Bose Acoustimass 10 series II speakers. I was pretty pleased until I found this forum. My question now is what do I go with for the speakers? I know the speaker system was purched for $600-700 dollars and I can't really go over that much if any. I've read some of the suggestions on other brands and was wondering what a good setup in this price range would be. Particularly, I was looking @ the Klipsh synergy quintet system on the BestBuy website, but I can't find a price. Any help would be greatly appreciated. By the way, I've already installed the Bose speakers, including the rear speakers mounted on the wall, so hopefully I can find something that will fit right in.
