[QUOTE="ngsm13, post: 3193452, member: 544830"] With the dimensions you gave, you'll have a total internal volume of 12cubic feet. This does NOT account for port displacement, driver displacement, or anything. This means if you built that exact box, sealed. It would give the drivers 12cubic feet minus their actual displacement. Using the specs you gave me. Your NET internal volume (the volume the subwoofers will actually "see") is 9.7cubic feet. With you port dimensions and length, NOT counting the flare, it will be tuned between 45-46hz. So, your enclosure would actually be 9.7 cubes tuned to ~46hz... even higher with the flare. nG [/QUOTE]
