you could try to make the hornpath wider.mayby it would get a little flatter.
the dip above the pasband is due to the big vtc.

Default Corner Thought Process No 1
Concider this end condition. The panel is extended right to the back for half its width. This gives a single defined path for the horn. The size of the cutout can be adjusted, and should give an area for the corner turn that is equal to or bigger than the area of the previous section.
