[QUOTE="FtheNutHuggers, post: 7379132, member: 632254"] check out the video i requested the OP to check out. note the 4 different response curves. those are measured in two different vehicles at two different locations in each. all 4 were using the same enclosure, just oriented in two different directions. each curve, if applied to a standard box modeling program would give the user a false sense of where the boxes were "tuned". moreso, they would suggest that there were actually 4 different enclosures, simply because they cannot account for the acoustic footprint of the vehicle the enclosures are in. there are applications where someone needed a specific subwoofer to have a particular bottom end in a specific vehicle, and the enclosure it took to reach the target response was physically tuned to 65Hz, yet had enormous output at 27Hz in the listener's vehicle. it's just a byproduct of useful statistics.
