the room is 1,2000 sqft. I am new to surround sound but i assume that 5.1 surround sound might not be a match for 30x40 ft.. I would like to keep the price under $700 but i am having trouble choosing between all of the speakers available. I also need some way of hooking my iphone up to the speaker preferably through AUX as I will be getting a new iphone when the iphone 5 comes out and they are changing the dock. i will not be placing the rear speakers at the back of the room, rather, just behind the point where the couch will be. thanks 😀
