We provide Theile/Small Parameters for those interested in
studying subwoofers further. We do not recommend you use
computer software to determine enclosure sizes or type.
While high–end enclosure design software may be useful for
engineering purposes, it cannot completely predict perform-
ance in a given vehicle and should not replace a real enclosure
that has been tested and listened to in a car. Please use our
recommended enclosures for optimum performance.
