Here it is
How do I figure out the cubic feet on this, it has to many angles I don't know how to do this. I can do a rectangle, but this?
I'd like to add slot ports, how do I figure that out on this box. 30-32 htz.
I'd like to maybe exit the subs, and ports at the top. I have enough room to add 3 inches to the top of the box also. I'm looking for 2 cubes per side 4 total if the depth has to come out thats fine.
The width has to stay the same, and I have 3 inches to play with on the height, and what ever on the front depth. the rear depth 3 inches could be added also.
As it is what's its cubic feet sealed ?
what size would the slots ports need to be?
Is there a formula to figure out port size to hz?
I'm looking to put 12's in there
any help would be greatly appreciated.
Thanks, Jeff

they have slot ports drawn but no dimensions, or tuning info.
