Sealed: 0.875 ft^3
Vented: 1.25 ft^3

That's per sub.

how big of a amp do you have to power the pair of subs?

2.5cubes before port and sub
and i would do between 25-37 sq inch of port, but i would shoot for around 31, it will give you a good mix between
spl and sq
and me myself, i do slot ports over round ports
i could tell you how deep the port needs to be for a tuning but
i would need to know the specs on the box your building
and where you wanted it tuned to

did you email me in regards to making this for you?

cheers dude, you recon i should head for about 31cubic inches inside the box then??

does the length of the post make a diference???

31 sqaure inch of port in the box

say like 15.5x2 slot port would be 31sq inch of port

i don't think i would make a slot port that skinny tho
but a good rule to follow is 10-15sq inch of port per every cube of air space

and port lenght is how you tune the box to the freq, for daily set up, something around 30-36hz will work fine,
most say 33hz is the sweet spot tune for a female, if you know what i mean, lol

here's a box i built for two type r 12's being powered by 1600watts

looks pretty sweet joakwin, im kinda new to custom car audio so is the best idea to build the biggest enclosure possable and then use the size of port to get the best sound out of it? or am i totally on the wrong lines???

[joakwin]

porting will be louder then sealed but if not done right it won't sound right
