this is the first ported box that i have owned. the measurements are 31.75 x 13 x 16.5 which i calculated to be 3 cu.ft. the ports are both flanged and the pipe is 4 inches in diameter and 17 inches in length. i calculated the port to be 24hz and the specs for the AA assassin is 32hz. I ran the calculation from the 12volt.com and found that my port length should be at 8.1 inches to achieve 32hz. what i dont know is how do i take into consideration the volume of the port and the variance of the flanges or are they negligible? i know that those also affect the cu volume of the box but i just have no idea how to calculate it.

any help is appreciated.

oh yeah i forgot to mention this is for 2 10" assassins
