Avoid placing the speakers exactly hatlway between the floor and ceiling. e If your music seems to be lacking in deep bass. try moving the speakers closer to the wall behind them and/or nearer to the corners of the listening room. Heavy, "booming" bass can be tamed by moving the speakers away from corners and walls.
