Ugh... I hate to be that guy.
Complicating things with theory and abstract minutiae has already been beaten to death.
Enclosure design is knowing what works, a higher order enclosure even more so.
Goals, suitability and install factor into every design, I can't count the times people wanted BIG lows outta a 3:1 4th utilizing something with an EBP of 130+. They saw it on YT so it must be true... lol
Of course its to be stuffed into a Cobalt trunk or similar.
Get with a designer and study his design, real world... you'll understand results and any recommendations along the way will make sense.
A legit design =
