If you make a ported enclosure and build it to the certain amount of airspace inside like for example 2.25 cuft and if you add a sloted port would that take away some of the airspace and would it make the airspace amount smaller? Thanx.
yes, when people or maufacturers say a airspace like 2.5 cubic feet, that is after all ports, subs, and braces are displaced, so an area of 1 cubic foot would be 12x12x12 internally, but if you add the sub and or ports, its that much less
