Im designing a box for a friend and i know very little but this is what i came up with. Is this even close to right for a box tunes to 36-37hz when the subs are seeing around 1.4cu a piece.

I know its probably not the way im supposed to do it but i created it in autodesk inventor and i can only share it as a pdf...

When i went here:

Subwoofer Enclosure Calculators, Fraction to Decimal, Parallel, Series, Port Length and Volume Calculators

and typed in my dimensions it came out to 12.02 inches

try 27 inches on a port 1.75 x 12 for a 35 hz tune in a ~1.4 box
