I have some QS4s that I am using as rear surrounds. Currently they just sit on top of bookcases that hold my DVDs in the back of the room firing straight out at 7ft height. I thought to buy a stand that I can screw to the top of the book case and the back for the QS4 on some kind of eyeball joint so I can aim them downward to the listening area. Anyone have any ideas on this type of mount, or is the way I currently have it fine and its a waste of money

tks
