Thanks for doing that. Very interesting. Kind of reminds me of a bigger JBL PT WG in some ways. No sharp corners but still quasi rectangular.
Couple of observations:
I think it is important to not be too quick to look at them and dismiss the differences. The difference in roundover in the horizontal versus vertical plays tricks on the eyes in terms of differences. If you study the area "scooped" by the various profiles I think the differences are better illuminated.
