I just purchased a Sony 5.1 system. With the way my living room is built I can evenly distribute the speaker placement as one rear speaker maybe closer to the center than the other if they were mounted on the wall. Then I thought about mounitng them in or from the ceiling. I was just curious what this would do the effect of surround sound since the sound will be coming from above rather than from front or rear at ear level. Another reason I thought of the ceiling mounts was because it would be easier. I know...that's just being lazy! LOL
