    enclosure impendance and peak port frequency?

    When doing some testing the other day I noticed when I played a 47hz tone I hit the same db as playing the peak tone of the enclosure (53hz). Im assuming the 47hz tone from the enclosure is the impendance drop of the enclosure. Would I gain a db or so by tuning the enclosure higher so that at 53hz the impendance is low and the peak of the tuning is higher say 60hz?? My cars resonant frequency is 53-54hz.

    the only way you'll know for sure is to build the box, and test again.
    sorry but there is no, yes or no answer

    Could be the res. feq. of your car you also might try and tune lower and have your box roll off at around 46-48hz. I've have seen gains of 2.5 db from going lower but hey you never really know till you try



    Audiobahn is like the Jessica Simpson of the car audio world, sure they might be pretty but its nothing you want to listen to...
