i need to find out the sizing of 2 tube ports for my box, i have calculated it and
according to someone he thinks the ports might be a bit too small, and i may experiance port noise so heres what i got
box- 21W 15D 15H which = 2.06 cubes.
i want it at 35hz.
ports- 2 - 2.5" diameter at 9 inches in length
so with those numbers would the ports be enough for the box
the sub is a 12" type R and the displacement is .071
