Woofer in Car
Please notice the green color curve. It is measured placing the mic at the passenger seat and playing the woofer from the trunk - all door closed. No one is in the car.
Notice how the cabin interaction with the woofer box......
There is a phenomenon of all frequency migrating downwards. As noticed in the Jwo Shong's Car Audio.
Therefore it is safe to assumed that the woofer does not need to drive so low, because we get free sound from the cabin space. More to be elaborated in the future.
