Thanks man ! I will avoid the corners with the subwoofer.
About the surround speakers, i'm afraid that i can't place them above my ears.
Although the pic says to place them in the sides as the best layout, i have to consider that they wont be above my ears in my room.
In that case, should i still choose the side layout, or the back would be best?
Is there any loss in immersion keeping the surround speakers at the same height of the front speakers?
Thanks again
