this box, according to my calculations, is 4.465 cubic feet after sub displacement. i want to add two tube ports on either side of the sub to help with visual appearance since i love symmetry.

what tube port diameter and length do i need for a 33hz "sq" tuning?

a pair of 4" ports @ 12.5" should get you there. That may not be enough port area and going larger will get into some very impractical lengths.

i must of been using that calculator wrong. every time ive tried to use that it tells me to use like a one inch piece of 2in diamter port tube which confused me because i see people using giant 8 inch port tubes 12 inches long which is why i posted on here

It all depends on my setup. I'm using 4 4" aero ports on my build. 2 4" pipes should be fine for you cut to the specs on the site
