    port size ?'s

    i will be building a box for 2 12" mach 5 spl subs box will be roughly
    4.5 cubes after displacements. i dont have a design for it yet tho.

    how do you kno all displacements if you don't have ports yet??
    typicaly aeros are 8-12 in^2 per FT^3 where as plot ports are 12-16 in^2 per ^3
    those are both just rule of thumb figures

    I would do an 8" port w/ a 4.5cuft net box.
    17" long will tune to ~36hz.
    13" to around 40hz.
