    $2 paypal for legit answer!!

    need someone to figure out port length, reward will be $2 paypal.

    PM me answers, no fucking guessing assholes



    putting (2) 2" port (pvc pipe) on the bottom passenger side.

    the box is 1.6^3 after displacements (other than the port obviously)

    how long in inches will the pvc pipe need to be in the box?

    Tuned to ~35hz

    Re: $2 paypal for legit answer!!

    im slightly confused on how you got the ft^3 number. is that a 4" top and 7" bottom depth? here are my numbers based on 0.75 enclosure thickness:

    gross volume: 1.114 ft^3
    net volume (not including sub displacement but accounting for the port): 1.073 ft^3
    port area (2" ports time 2): 6.283 in^2
    port length: 11.387"

    assuming that you had wwo of these enclosures with one 2" port per enclosure, then the port length would be 4.753"

    so what is it?

    ^^^^^what he said^^^^^

    Your math is off, that box is 1.114 cubes with NO displacements assuming
    the measurements are correct (40x14x4-d1x7-d2)
