Paper Calculations

[AP Zoutes]

so this is what I came up with

before dispalcement your volume is 36.83 ft3 = 1042.9 liters

I assumed a total sub displacement of .7ft3 = 19.8 liters

I also suggest alot of internal bracing with 2x4's displacment = 2.0 ft3 = 56.6 liters

which leaves 34.13 ft3 = 966.5 liters

for your port 203mm wide x 856 mm tall x 297mm deep =29.76 hz

after port displacement you have a volume of 32.31 ft3 or 914.9 l

This is a big ass box

If you want different tuning let me know

[AP Zoutes]

btw the lowest you can tune this is 29.76 hz. (297 mm deep) any longer then that and the hump gets in the way. you want the port to end at least 203mm before the hump. but you can go higher

[AP Zoutes]

the port walls will basically just go from the internal top to bottom. this is still a small port but is the biggest possible with the baffle area left after the subs are installed. any smaller and you will get port noise.

first off thanks so much for doing this. now hmmm yea i know the box is a big one cause its almost the whole car. SORRY about the port dimensions i gave you it was supposed to be 33cm and 330mm my bad.

[AP Zoutes]

alright let me re-calculate

btw the lowest you can tune this is 29.76 hz. (297 mm deep)   but you can go higher

ok i dont really know alot about tunning but i know 29 is quiet low... this whole project is for bass boxing so i thought cause the song is between 50-55hz is it alright to tune that high?

[RichardXTC]

alright let me re-calculate

yea cause each sub takes up 400mm so 1140-800 =340mm

[AP Zoutes]

I was leaving 50 mm from the edge of the box to the sub. but I'm working on this.

[RichardXTC]

OH YES hey dam forgot about that. also the tunning questions i asked above^^^

[AP Zoutes]

I"m trying to get the tuning higher. Will take a minute
