I would like someone here to help me design a box or build me one with these specs L33 W19 H14. I would like it to be tuned to 35hz. I also don't get how to use the Torres box calculator (noob). I have a 4 inch aeroport, but I'll go with a slot if I have to. This will be running off a Saz 1500d at 2 ohms.
