Ideally, I'm sure the space helps, but I'm wondering to what degree. They also recommend that the surrounds sit above ear level more than their stands put them, but I use the stands and I'm not dissatisfied with how they sound. Wall-mounting won't be the best option when I'm in the basement, since the room may actually end up being wider than it is deep, depending on what the final layout is. That's why I figured I'd go with ceiling brackets, for flexibility, and it would put them in the suggested range for height. However, if it compromises the sound at all, I may want to work something else out.
