No need to round the edges of the cutouts. As for the insulation, the section on the braces is horizontal, just like you saw. That's really important. It completely covers the brace, spans side to side and fore to aft. When the insulation is installed on the brace, it looks like it divides and separates the chambers from one another. And in a sense, it does - midrange frequencies cannot pass through it. Bass will pass right through like it isn't even there though. So it forms a very good midrange "trap" and damps the standing waves that would otherwise be present.
