[QUOTE="winkychevelle, post: 8814188, member: 611804"] No not necessarily. Say you gain 3db at 30hz that gain is fixed it's not a single peak though it's it's own response curve you may gain 3db at 30hz but 1.5db at 32 and 1 at 34. This is why you have to measure the difference inside to outside. Do you get the whole response curve of the peak. Raising the tuning may raise the overall peak by letting the cabin gain roll off and the box take over. This typically means less efficiency. Knowing the actual response curve helps you couple the cabin gain to the box response curve. It becomes much more predictable to model. Most sub box programs give you the free air response curve. Some have features to help predict cabin gain but nothing beats an actual measurement [/QUOTE]
