I don't know. It's just info that he gave me. These numbers and info of this type is beyond my comprehension.//content.invisioncic.com/y282845/emoticons/redface.gif.62fdbfe1a101588a808c4cff71bcb942.gifWhats the point of telling us what the QTC is? Its going to change once that enclosure is in vehicle.
I see, so basically qtc is really related to frequency response? So, if one is really looking for their sub to really pound the lo notes the enclosure maker would design with qtc that would help to provide that kinda response?So basically a QTC of .707 is the flattest response of a subwoofer in a sealed enclosure. He is basically showing you that in the perfect environment your subwoofer is near flat response.
