so you're telling me that the 0-80hz can hurt your ears?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
A box has a tuning frequency, which is basically the frequency where the back wave from the sub is most perfectly being inversed and coming out in phase with the front wave of the sub.Besides the subwoofer enclosure itself, wouldn't the T/S parameters of the subwoofers come into play too regarding the tuning of the port? Not all subwoofers of the same size are created equal!
