Hurtin' feelings errrday.
You are using the diameter of a circle to draw these conclusions which is absolutely wrong.
Dude, your calling out of one the best designers/box builders on here. Guy has been doing it for years, has had multiple successful people on here and all you can say he's doing it wrong? I would highly suggest you rethink your thinking status before this gets blown out of proportion. He obviously know's what he's doing.port area of an octagon with 9.5" i.d. = 63.45.. Port area of a circle with a diameter of 9.5 = 70.88
He clearly used the circle dimensions as shown here. With octagon dimensions you end up with a lower ratio, less airspace due to thicker walls, and higher tuning. I would have gladly accepted suggestions if they were correct.
