    Porting a shiva

    The plan is to port my shiva mkIV in a 2cu ft box tuned to 30 hz. Anyone have sucess with this sub in a ported box?

    I know it has a EFB(Not sure what it is exactly if the abbrev. is off) of 52. Anything <50 is for sealed and anything >100 is for ported. I'm guessing its ok to use a ported box for this sub.

    If this works with one, I will be sure to add my other shiva in this type of application.

    Re: Porting a shiva

    So the EFB is just a guide, not a rule, correct?

    This is car audio. What rules? You could put a Shiva in 0.25 cubes ported to 12hz if you wanted. =p
