help with port

Recommended Posts

ok so im helping a buddy of mine build a sub box for his truck

its a regular cab F-150

the sub is a 12" TE model treo sub

it has for ported specs from their website:

1.6 cu ft net ,16sq in vent, 18.5 in long, F3=31HZ

so i design a wedge box with the dimensions of : Height = 13.5" , width= 40.25" , upper depth = 7" , lower depth = 8.5"

he wants it tune to 31Hz

so i came up with these dimension for the ports:

two 2" ports on each end about 5 in long

know i really not sure if this is right or not was wondering if someone could give me there opinion.

i dont have a box building program so i did this all my hand just some math work.

thanks for your time!

well thats the same measurements i got ,

but i guess i was more talking about compared to the specs the treo website gives out .

im just wondering if the setup looks accurate or do i need to make some adjustments ?
