    Box numbers please double check

    I got my calculations from the 12volt.com. If anyone can double check these I would appreciate it.

    Box

    W=29
    H=11.75
    D=10

    Port

    W=1.6
    H=10.25
    D=23

    Sub Displacement .05

    port displaces .218cube + wood thickness

    so depending on your wood, it is ~1.7cubes after sub and port

    working on the tune

    Re: Box numbers please double check

    According to the 12volt.com without port displacement or woofer displacement I am at 1.38 cubes.

    10 X 29 X 11.75

    multiply those three numbers together
    3 407.5 (cubic inches) = 1.97193287 cubic feet

    then it all depends on wood thickness

    Re: Box numbers please double check

    if your using 3/4" mdf and 29x11.75x10 are your external dimensions, then i calculated 1.0159 after port and sub displacement

    sounds right

    It is a 8 inch sub and it is exactly what DD recommends. Most places would suggest a 3 inch aeroport which would still work fine for daily driving. 30 inches for an 8 inch sub would be like almost having 3 4 inch aeroports which would be a bit overkill. Bro
