new box design

[Decipha 10+ year member]

Heres my new box design:

14.875W x 12.5H x 18.5D INTERNAL

1.99 cu ft - INTERNAL

30 hertz tuning

14.875 x 2 port face

Is 2" enuff port?

if my calculations are correct i believe i need to have a 38" port ??

if thats correct how do i go about making the port that long if the height of the box is only 12.5 inches internally? Do i make 4 walls 9.75" with a 2 gap between each?

a port that size is going to drop your airspace to under 1 cubic foot when the sub is installed

alright how bout i keep all the same deminsions but lower the port face to 14.875 x 1 and have a 26.5" port ? that would give me about 1.5 cu ft and about a 30 hertz tuning correct?
