Here is a behind the scenes video from the day: https://up-tube.com/upvideo/eWVp1vNDqCj

High Speed camera courtesy of https://www.aimed-research.com/. They rent high speed cameras at killer prices. Hit them up.

ELI20 version: I answered why you want a large outlet area but not necessarily why it curves like that. Anytime you have a sudden change in cross-sectional area in the horn you will get waves reflecting back at the source. You don't want that because that is wasted energy that could have moved forward. Even if it goes from a small cross-section to a larger, if you do it suddenly you get those wasted waves. So you want the horn to basically be asymptotic at the exit so you never have a jump in discontinuity when it exits to the wide open air. So a directors cone isn't as good as the curved shapes I showed because it still has the sudden change when it dumps into the open air.

Summary: I made a huge horn and broke glass with it and explored why horns are shaped the way they are.

25 MILLION Orbeez in a pool- Do you sink World's Largest Horn Shatters 6 months ago   07:01

Kevin (aka The Backyard Scientist) and I filled a pool with 25 million waterballs (aka Orbeez) so I could settle an argument about how far you sink if you jump in.

Go watch Kevin's video- https://up-tube.com/upvideo/OQF4QUkCDER
