vented subwoofer enclosure help please?
when you calculating the volume of the subwoofer enclosure do you exclude the port area as well or include it in the calculations for the box volume?
its confusing me because ive been trying to used online box enclosure calculators and when i put my dimensions for the box it shows that my volume is 3.9 cubic feet but then when i plug in the port dimensions it goes all the way down to 2.7 cubic feet
The port volume subtracts from your total cu ft i.e. 3.00 cuft gross volume with 48sq in port volume x 16" long , your port will take up .44 cuft of air space which will leave you with 2.56 cuft net
You have to subtract both your port volume and driver displacement and any other bracing used in the enclosure
