First run AoS. Enjoy the process

Really sorry for any English mistakes . I put my satellite speakers opposite like this in my room:



Am I correct? Must I put the speakers exactly? (What I mean is : "Left speaker to the left ear, right speaker to the right ear" like headphone)

By the orientation of your head... you have labeled the speakers backwards, or placed them backwards. But that's okay, because the channel orientation doesn't matter. That setup is much like what I use when I use external speakers at night. I just put them closer to the pillow. It creates this awesome "bubble of sound" in which I sleep when I do that.

About ASC for an hour, that will unbalance things for a day perhaps, but that's it. Avoid doing that.
