Bear with me guys.... My room is pretty tiny for a 7.1 system. Since the 6th and 7th channel are matrixed Im not really missing out on anything by going with 6.1 am I? I just want to make sure I understand this correctly. 7.1 is the same as 6.1 but more for large areas that are spread out and need two rear centers? Also how would I hook up a 6.1 system? All the 7.1 recievers have a left and right rear surround so how would you hook up just three surrounds instead of 4?
