Would I be right in thinking that if 1 sub needs a box with a volume of 40 litres, then 2 of the same sub will work best in a box with a 80 litre volume? Or should it be slightly less?
Also, does it matter what shape the box is?
I know I could make 2 boxes and stick em together but I would prefer not to have to do that.
