I really need help figuring out dimensions for a ported box for my Sq hdc3 12. It'll be on about 2000-2400 watts. And I want it in a ported box at 34-38 hertz. I've tired using the sub box calculators but can't figure them out. And I don't get how to subtract the displacements. But I was thinking of having the box between 2.75-3 cubic feet after sub and port displacement. And I want a slot port. This is my second box I've built so I'm still new to it. Building it isn't the problem for me, it's figuring out the measurements. Thanks in advance
