IN my dedicated room I have 4' x 2' x 2" panels behind my sofa, two upright and the third across the top of the other two. Top one angles away from the wall and touches the ceiling as the ceiling is low. Also have another 4' x 2' x 2" panel at first reflection by right speaker and another on the ceiling. The left speaker is by French doors with kilo serge wool curtains as used in vocal booths.
