Is the panel 1 piece? Meaning, is the black banded portion the same piece as the above artwork? If not, then I like the right with the mesh grills, it feels more like a traditional backbox. However, it appears these may be one piece, in which case, I would actually argue to extend the artwork down to the bottom and go with the layout on the left. This would have more of a Cirqus Voltaire full backbox feel and the small holes from the left option would blend into the artwork and would look less intrusive than the black bar at the bottom.
