I'm from Brazil, and here we have several styles of boxing in different states of the country. And in the Northeast region of the country, the 15-inch inverted speaker horn box is widely used, in various types of systems or channels, with a 60cm box; 50cm; 1m (23.622 inches; 19.685; 39.3701) of horn, and 32 liter liter housing, varies from project to project and housing developer.
!I wanted to know what program I can design them!
There is a box that has the DUCT, right triangle with rectangle. (here in Brazil we call the air passage a duct) And I managed to make the square area of it, but I don't know if it's right!
The math I did was this: I multiplied the sides of the right triangle and divided by 2, and the sides of the square multiplied. Example: 12cm X 12cm= 144 ÷ 2 = 72cm².
Square: 42cm (width) X 7cm (height) = 294cm².
Once you have these 2 results, add the 2 = 366 to the area of the 2 together. I don't know if that's how I calculate. I used centimeters, but you can convert the measurements you use and test.
