Ok, so I'm ordering an Fi 15Q tomorrow, I just got done designing the box wanted to know peoples thoughts + someone looking over it to make sure I did everything right.

Building a box of 3.2ft^ @ 31hz

box is 15 x 27.1 x 17.5

total port = 21" (20.9)

Sub displacement is .19
port displacement is .15 (.1458)

box after sub+ port 2.86ft^

That seems like an awfully small amount of port for that box much less for a 15, but I also don't know a lot. Also, you didn't tell us how long the port is.
Maybe less port area works for an SQ based sub like the Q? But still, that isn't even a whole 10^2 per cube.
