We provide Theile/Small Parameters for those interested in studying subwoofers further. We do not recommend
you use computer software to determine enclosure size or type. While high-end enclosure design software may
be useful for preliminary engineering purposes, it cannot completely predict performance in a given vehicle and
should not replace a real enclosure that has been tested and listened to in a car. The best a computer screen can
do is give you a visual representation of what something sounds like. Please use our recommended enclosur es for
optimum performance.
