1) Net volume is AFTER port and sub displacement.
2) You have 20.375" of port length and you need 23.15" to get a tuning frequency of 36hz.
3) Port length extends 1/2 the port width from the end of the port if one side runs along the wall of the enclosure.
4) You can find the enclosure volume much easier than breaking the enclosure into sections manually.
From there, take the number they give and multiply that number by your height and then divide by 12. You can also see from the picture the actual port length (the solid line drawn down the center of the port).
so i did wat u said heres a pic
on the port i went out 1.5" from the middle of my port?
how bout now
thanks man i appreciate all the help
this box is for two type r's...12"...they reccomend 1.7 cuft a piece or 3.4 for 2 but i dont have the space should this work well.. jw if you know
thanks again
Have you already bought the 12's? ...If not buy 10's and they will love that amount of space

thats not enough space. do one ported in there.
4x 12" HDC3's
1x Hifonics Maxximus (rated 10,[email protected])
2x Powermaster D3100
8x runs of 0 gauge
1x stock alt
155.2 dB legal (vehicle off and @50Hz) in a Ford exploder
im sort of limited... how much space should i give them my original goal was 3.4cuft.. but i really cant do that w/o moding.... how much space do you guys reccomend.... and do u think i should tune differently..? maybe 30? jw i like the sound of a 30hz wave better than a 36 but idk if its becuase my car shakes more or wat??.. idk just need some advice thanks..
No point in tuning it low in a small box.....I would do at least 4ft^3 at 30hz
