[QUOTE="winkychevelle, post: 8814206, member: 611804"] That is dependant on vehicle and that vehicles cabin gain. Without cabin gain a ported box would peak at tuning. If you are tuned low and in a larger vehicle it is likely that you peak higher than tuning because cabin gain couples with the box peak makes it that way. In a small vehicle you could be tuned to 36hz and peak down in the low 30s. My truck peaks lower than box tuning by a bit this helps me extend my subs frequency response to be flatter for a wider range by tuning the box higher and using the cabin gain down lower. If I tuned to my cabin gains peak it would couple with the box tuning and I could gain db quite easily. But it would be a very peaky response curve [/QUOTE]
