Luc, sounds to me like you and your wife are starting to realize the benefits of proper speaker positioning and the merits of the QS8 in your own home. Surrounds are meant to be on the sides not in the ceiling and certainly not behind, a rear surround channel is just that a rear channel, if you look at THX's suggestions for positioning of the rear channels for standard def sound the center is either a single or 2 speakers set close together, for HD sound they have 7.1 and the rears are wider apart.
