Box for Fi BL. IM NOOB AT PORTED

[Propimp 10+ year member]

just found out the wifey ordered me a Fi BL, 18" for the mini van. I have NEVER built a ported box in my life. I need help with a LOUD box. Pretty much all out SPL. I listen to rap all of the time, I have no clue about what to tune it to and what the hell it means. I know that i like the flat respone of a selaed box but I want this van to be loud.

On the Fi website it says to build a box 6-10ft3. can any one help me. If it matters it will be powered by a MTX 1501d (old good one)

make it 7cu.ft NET with a port of 90sq.inch and 26inch long

formula for checking volume:

( height x width x depth in inches ) / 1728 = x cu.ft

for example:

a square enclosure with 12" INTERNAL DIMENSION ( you add the wood thickness to determine the outside/all around dimensions of the box) :

(12" x 12" x 12") / 1728 = 1cu.ft

now NET volume means without the sub displacement nor the port displacement....

make 110% of your math and calculation before cutting the wood.
