well it gives a port length and port diameter which leads me to believe its a cyliner, if the port was rectangle then it would give a width and height instead of diameter.

edit: also in the diagram it says "d(internal)"

lol too early for that much stuff crammed together i guess. i completely overlooked diameter lol.

http://www.carstereo.com/help2/Articles.cfm?id=31 use this to calculate you a vent slot port. if you listen to mostly rap i would tune it to 32hz and 1.75 cubic feet internal.

lol'd

hopefully this will give u some motivation to make a bangin box!!

its not rocket science to find the area of a cylindrical port.... 2(pi)r(h+r) but just stick with your sealed box imo

i had a box, 2 mtx 10's with 4 3" wide 7"1/2 deep round aero ports it sounded pretty dam good for 10's

thanks for the link



lol I'm an engineer, I think I know my way around finding the volume of a 3 dimensional shape...
