The wall behind the speakers is 10f with a window that covers 3/4 of it with a thin courtain, the distance between each speaker is 7f, the distance from where I set to the center between the speakers si 9f. The acoustic of the room should be on the warm side as it has carpet on the floor and roof. The is a sofa with many pillows. The speakers have a bit toe in, the twitter should cross well behind me
