i have about 33" wide x 15" tall x 50" deep space available. i need to make a box that will get the loudest SPL results possible out of 4 of these (http://www.cardomain.com/item/INFPERFECT121). i already know it should be ported and tuned to about 35hz. question is how in the hell do i know how to tune it. need help :(

i want the box to house all 4 subs at once, facing up most likely in a square.

I would do 9cubes NET (after ALL displacements) tuned to 32hz with ~100 sq. in. of port.

Subs firing up as stated, port towards the rear on the bottom of the box horizontally.

and that is:

with .75wood thickness

24" of port length (31.5"x4"---126sq.in)

same dimensions as u said except that 50" become 48"
internal dimensions become

46.5x31.5x13.5

therfore, ull have 9.4cu.ft, add them sub, and ull have 9cu.ftNET tuned @32hz
