I am building subwoofer boxes and I have the basic idea of building square & rectangular sealed enclosures (L x W x H = X / 1728 = enclosure volume). I would like to know how to build boxes with different top & bottom depths, slot ported, labyrinth slot ported, tube ported, tuning frequencies, how to calculate their internal volume, & how they work? Any help would be greatly appreciated.
