    2.35ft^3 box with 1 4'' aero port total lengh 18'' with flares on both ends,what hz??

    hey guys not sure how to calculate flared ports on aeros so i need a quick check...like i said box is 2.35 cubic ft with one 4'' aero port with both ends flared and its total lenght with flares is 18''...what would this box be tuned to and how much port displacement?



    Current system:
    03 Ford Explorer
    iraggi 300amp alt (on its way)
    Red top under hood and deka 9a31 in back ( on its way)
    stock mids and highs
    Pioneer Z110bt headunit
    1 18'' TC9/Audioque In 6cubes tuned to 32hz
    Audioque 3500D
    Handles the lows just fine

    radius^2 x pi x length(I use the full port length to make up for the flares that I'm not accounting for, instead of taking 3/4" off for the baffle), then divide by 1728.

    (2.125^2 x 3.14 x 18)/1728 = .148ft^3

    yeah for displacement you need the outside diameter divide by 2 to get the outside radius

    Once you figure out port displacement, don't forget to recheck net volume. It will change the port freq.

    right smaller box = higher tuning keeping port the same
