Aha so it is that complex huh. I wonder why. Things are more demnsional than they seem. I would have never thought that putting surround sound in your room would be so complex.
I wouldn't put it near your other speakers. I think it is made to enhance your listening pleasure so I would say stick out somewhere where it's not near all your other hardware.
It's made to enhance your other speakers, you don't want to throw them right under your main speakers. That to me is pointless. You are looking for contrast.
