..i got everything...i mean everything that ill be using and what i want to do so its pretty simple :P but i need someone who can sucessufully design a box using 4 inch aero ports with 6" flares ......i have 3 of them but i wont need em if i dont need to.
Dimensions for the box including wood to were it will fit perfectly....
30" wide
26" deep
13" tall

i would like to use dual baffle in the front so the internal measurement's after displacement of wood and everything is this
28.5"
23.75" dual baffle included.
11.5"
this is whats available for air space....
and this comes to
7784 then i take 1728 and it leaves me with 4.5 of cubic air space, then remove the displacement of the sub im using, .6, which now leaves me with 3.8 cubic air space...thats what im left with when its all said and done now what i need is someones help who can actually design the box and make it were the aero ports are firing in the box, were it just shows the flares on the outside, not the tubing. so its nice and purdy flush but heres what i need to do i have 3 4" aero ports that i want to use for daily driving in there, or how many ever i need, but you have to remmeber that the box is 13" tall but its really only 11.5 so i cant have 2 tubes ontop of each other because the flares make them 6 inches in diameter....so if someone can help me create a box, for this sub woofer with everything i gave them http://www.elevationaudio.com/xspecs.htm < thats the specs for the X woofer but if someone can do that that would be awesome....

is this confusing? or is it pretty well layed out i just wanted to make it as simple as possible for the person who wanted to help me, its basically already got everything...i mean everything internal space what im working with i just need to get someone who can find the length of the tubes for like 30-35 hz's and what not like a cut sheet and everything can anyone help

ive seen it done a few times, so im pretty sure if there is a neg effect its probly small.

now no one is gonna be able to help u tune the aeros for SPL unless they have everything the same you have, sry. The trick to aeros in SPL seems to be Trial and error, make the box to your dimentions ,stick the aeros in and get metered. Then slowy cut down the aero's size until u stop gaining, also cutting down on box volume also seems to help alot with raising the tuning.

as far as daily i cant help ya there except tape over the ports to make the box sealed, thats my plan when it comes to daily.

the ports are listed as how long each one needs to be on the calculator. the more ports you use the longer they need to be. you might need to go with 2 ports because dont forget you need clearance behind the ports of about 6 inches for proper use. I used 2 ports tuned to 40hz in a 4 cubed box and it is perfect for street bass, they are better than my slotted box too. I wouldnt bother with 30hz tuning. I would go with 35-40hz for daily driving.
