12" Shiva Box Plans w/ pics

[8inw7]

Lv = 49.67"
Av = 56 Square Inches
Vb = 3 cu. ft. = 5184 cu. in.
then add 183 cu. in. for the sub displacement = 5367 cu. in.
Fb = 30 Hz

Those are the numbers I found using formulas and such.

Please check if this is correct or if I messed up something somewhere. I spent so long tryin to figure this crap out, so I'm not sure if it's right. I had to set up systems of equations n **** to find depth and the length of the bend around the right side, so i dunno if it's all good.

Same pics hosted 2 dif. places

I hate to bump, but i went through a lot of trouble figurin this stuff out. I just want to make sure i did it properly.

its all pretty close. id round everything to the nearest 1/8th inch though to make it easier to cut.

How is it just PRETTY close? I made these numbers exact as hell... I accounted for everything including end correction then i even accoutned for the end correction to affect the volume of the box.

I just posted this to make sure i didnt do anythign stupid, cause thsi is the first box ive designed.

Oh and ya ill definitly round, i was just doing that so i could know exact numbers.

thanks for the info.

Oh, and btw...you know how you have that pic in ur sig.? What is the black stuff in yoru port so it looks nice?
