The problem is there's a (wall-mounted) shelf immediately to the right of the desk, which needs to stay where it is, otherwise I would just let the speakers hang slightly past the edge of the desk. Desk is 37" wide, and the monitor is 22.5" wide, so the absolute maximum is 7.25" without shifting everything off-center. 7.5" would only require a small enough of a difference that I might be able to live with it.
