System Type 1
System Description
In this system type, the woofer and tweeter are mounted close together. While the kick
panel is one of the more common locations to achieve this, it is certainly not the only
one. What is most significant, is that by mounting the two drivers in close proximity with
a minimized off-axis angle at the greatest distance possible from the listening position,
it provides one of the best arrangements for optimum imaging in the vehicle. Since
there are varying degrees of axis and pathlength that will be achievable for each driver
in typical installations, four basic configurations are provided to accommodate the most
common cases.
• Type-1A is the default setting of the network, and assumes essentially on-axis positioning
with equal pathlength of both woofer and tweeter to the listening position.
• Type-1A (Option) is as above, but provides a more shallow roll-off and lower Q for the
tweeter high-pass filter as an alternative.
