CONGRATULATIONS!
You now own The Mule, a first-of-its-kind
subwoofer designed to reproduce extremely high levels of SPL at a point in the
spectrum where the resonance god lives. This precision component, when
properly installed, is capable of exciting the air in your vehicle to a level where
it can vibrate the metal skin of the car and shake your world.
Should your woofer ever require service or replacement, recording the
information below for your own records will help protect your investment.

Two frequency response curves are shown for this design, one for predicted
“In-Car” response and the other for “Half-Space Anechoic” (out-of-car)
response. The performance difference between the two curves is a result of
the natural acoustics of an “average” automotive environment. This “average”
transfer function is only an approximation of what you may expect to see in
your car. Every car is different.
The curves were generated using 2.83 Volts and measured at 1 meter. Also,
each frequency response curve includes a 12 dB/octave low pass filter at 100
Hz.
