  1. no i meant 30.95 Hz. That's what I came up with after I added up all the displacements for real, your dowels go the 32.5 inch way right?

    yeah there cylinders, one top to bottom (13.5 inches) and the other side to side from port wall to box wall (25.75) no dowel in port and there both 1inch thick

  2. y would it be 30.5? it says inner dimensions so doesn't that still make it 21.5? and its 3 common walls and .28 woofer displacement with 1 baffle

    because you are adding a 9 inch extension. 21.5+9= 30.5 Then you see I added 9 to the length of external port? that shows the calculator that those extra 9 inches will not be inside the box therefore they will not be subtracted from the net volume.

    EDIT: Your final tuning will be 30.95Hz if you add that 9" extension.

    dont you mean the final tuning will be 31.34hz with 30.5 port length. and thanks i was worried that i would only be tuned to 34.95hz with the extra 9 inches

  3. (2 12s) my box is 15high x 32.5wide x 25deep. (25 deep with baffle over subs) the port length is 21.5inches all together and the box has 2 1inch dowels crossed for bracing. port is 13.5 x 4.5 and i believe tuned to 36.33hz, i built a port extension (9inch) what will this make my tuning? and how much of an extension do i need to tune my box down to 32hz?
