    what is the displacement of a 12" XXX...Jmac...anyone??

    I need to know the area the driver takes up inside the box. Here are the specs:

    12XXXQ1.2

    Fs 34.4 Hz
    Qms 5.19
    Qes .49
    Qts .45
    Vas 31.6l
    Sd 480cm^2
    Xmax 32mm one way

    SQL: 2.25 cuft tuend to 33 Hz
    SPL: 2+ cuft tuned to res freq

    Also, it says 1.25 for sealed. Is this w/o driver displacement, or does it need to be 1.25 with driver displacement?

    99% sure its w/o driver displacement. when they give specs like that, its usually not including the driver (and port) diplacement.

    im sorry i dont know the displacement of the xxx



    when in doubt, check the ground.
