Box for 2 15" Earthquake Subzero's

so i changed the port to 5"x20" (which if im doing it correctly) should be a 4:1 ratio? effective length is 24.75" I looked up port ratio and Triticum Agricolam mentioned its better to get it as close to square as possible, am i correct?

Yah thats an example. Im no box builder, i just remember reading somewhere about port ratio and it having to be a low ratio rather than high ratio. How low?i dont know.

I assume square is optimal, becuase aero/circular ports tend to be seen as one of the most efficient ports. I have no clue of the science behind it or anything man lol im just a noob passin on some things i remember reading. Hopefully it helps out ur box build.

The more square, the more efficient, yes. Lower ratio requires less area, higher ratio requires more area to increase efficiency and decrease noise and compression

yea it definitely helps! and your totally right i didnt consider port ratio at all. i did a little bit of reading on it and lower seems to be the popular choice.

thanks for the info man! i always love learning new things on how to make my next build better
