I have been thinking about different port options and shapes. Due to my space restrictions I was thinking of putting 4 triangle ports in each corner of box to save space and mount subs in preferred way. My question. Say I put in all the specs into calculator to get length of a square port I can simply divide length by 4 and then ofcourse 2 triangles will equal square and that would be correct? Same type math if I found the length of a slot ported slot and wanted two slot ports, I'd cute width in half and then length divided by two? I'm wondering if my math is right on this and would this work. A single port better than multiple ports? Is there any other variables to add to the equations of port? I already know the 12-16inches squared per cubic foot. Just anything else to be aware of as to why this wouldn't work or be best option.
