Baffle shape

from my own research ive found the first few inches from the baffle very critical in the design of a horn, and im sure this is why function one allso design there horns in the way they do. But this leads me to want to rethink the way we design baffles...... in most designs the baffle is allways the same....... letterbox style...... is this the best way to go.......

but does it..... ill need to do a quick sketch to help me explain why i dont think it is...... the half circle is something ive been thinking about.....
