for slot ports, 12-16 square inches per square foot of box space.

i know that but i need an equation to find the port area of a port cuase i need to get 132 sq*2 inches of port area at 35 hz for an 8 cube box net
thanks
i was wondering this to.
bonesninja, so if the height is 14" and the width is 3 1/2" it would be 14x3 1/2=49 so it would be 49 sq*2 of port?

dont include the port in the volume. if your port is 8"x14"x X"L, then you need to figure out the overall displacement using external dimensions of the port. then subtract that from the net volume of the box (using the boxes internal dimensions).
i always figure out the box size i want, then the port i need for that box, then build the box that much bigger to accomodate the port and the volume it takes up.

and someone needs the tuning curve chart. if you want to use round ports, here you go.
