Confused On My Box

[t-rob]

i have 2 12" kicker l5 4ohm dvc

and am making a new box...

the one i have now is tuned around 38hz

and want to bring that to 32hz

i have max dimensions of 35.5"w 18" H 18"d

i have tryed using some calculators online but it just gives me some weird ass dimensions for the port

i was wondering if anyone can help me and tell me how i should go about this..

3x 14.25 at 33hz good enough?
