I need help on setting up my Logitech Z-5500 speakers in my bed room... My computer is set up in the corner of the room, and it is hard to find a good spot to place the speakers... this is a diagram of how it currently is... is it alright? or should I move something? Also, are the front speakers supposed to be louder than the rear ones? Mabye Im too far from them?? Or too close to the front ones?? I cant place them anywhere on the floor because there is no room, and I cant place them anywhere on the ceiling, because it is just foam tile, and wont hold... so they have to be on the wall somewhere..
