well guys i am confused here and i can't figure it out does five 3 inch ports equal to one 15 inch as far as port area????? i know it is simple but i need to make sure for my design.....or also does two 6 inch ports equal one 12 inch port?????? well guy some feedback would help me out a lot.

Middle school geometry - area of a circle is equal to pi * radius^2.

For a single 15" port, that would be ~176.7 sq. in.

For five three inchers, it'd be (7.06) * 5 = 35.3 sq. in.

thats what i got 2 but i was curious because when u calculate port lenght they are pretty close when u add the 5 3's together

well thanks for the help i know it was elementry but better safe then sorry guess i'll have to try something like four 6 inch ports.....slot ports are easier to deal with...one more question. do u count flare on lenght and surface area as well????

Thanks again,

Brock

yep, flare does indeed factor into length, as it is part of the surface area.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

how do u calculate those? I am goin to use four 6 inch ports with an inch of flare on both ends of all ports...also I was planing on doin exterior ports entering towrds the bottom rear of the box, about how far a part do they need to be and how far off of any walls?

Thanks,

Brock
