Hi, I have a pair of KEF five Two 'surround sound' speakers. On my amp, I need to set the speaker distances from the listening position. My problem is that as the speakers are 'physically' all (center, left, right, sourround left and surround right) in the same place, should I set the distance to where they 'would' be (where i would physically install them, a couple of meters from the listening position) if they were a typical 5.1 system? Or should I set the distances all the same?? Any help/advice appreciated. The amp does have a MCAAC system but I've lost the microphone when we moved house.
