Crossover Network Introduction
It is common knowledge that the automotive interior is one of the most inhospitable
environments for high-fidelity sound, and that every vehicle poses its own unique set of
installation and acoustic challenges. While many of these problems can often be overcome with proper speaker placement, equalization, or other techniques, the attempt is
a time consuming task without guaranteed results. Yet with all these tools and methods
available, it is surprising to realize that one of the most powerful tuning tools has been
misunderstood or neglected by so many for so long. It is for this reason that Alpine has
developed the most advanced crossover network design in the history of car audio.
Much of the difference between demo-board and in-car performance can be attributed
to the fact that crossover networks have been traditionally tuned for only one specific
application – usually the demo-board. Without taking into account typical real world
installations, the transition between drivers and resultant frequency response will be
degraded for the majority of vehicles that installers are confronted with today. Through
Alpine’s unique phase coherent flat summation design methodology, however, it is now
possible to optimize performance for a variety of installations by intentionally altering
various filter characteristics. By achieving an “in-phase” condition between drivers in
the overlapping frequency range at the listening position, image smear, response aberrations and other typical problems can be dramatically reduced or eliminated altogether.
This “phase linkage” technique can be thought of as a kind of passive time correction in
the crossover region.
With Alpine’s introduction of such revolutionary processing technologies as digital time
correction and adaptive equalization, all of this may seem superlative. Unfortunately
however, such processing can significantly increase system complexity and therefore
may not be practical for every situation. Additionally, without careful use of time correction for each individual speaker in the system, integration problems between them can
remain. Subsequently, it may be advantageous to use such processing to compensate
for seating position bias in conjunction with the phase correction of the passive network
for the transition between individual drivers. Simply stated, the flexibility of the
AlpineF#1Status™ crossover network allows it to be a complimentary solution for achieving the best of both worlds, either as a stand alone solution or an integral component of
a partially active system.
English
As with all AlpineF#1Status™ products, it is the attention to the smallest details that
truly brings out ultimate performance... or in a word, MicroDynamics™. From the hand
coated crosscut wood fiber cones to the symmetric drive motor structures, nothing is
left to chance. This philosophy is carried throughout every aspect of the SPX-Z18T
speaker system, including the components, layout and design of the crossover network.
All series capacitors are the highest grade metalized polypropylene, and all series
inductors are heavy gauge air core. Even parallel inductors are of powder core construction, to maximize consistancy and sound quality. All elements are intentionally placed
in such a way to as to minimize any chance for magnetic or thermal influence, and all
signal path lengths are minimized with extra heavy circuit board traces. In the end, this
level of quality and attention to detail has but one purpose, to bring true sonic realism to
the automotive environment once and for all.

Jumper Group Function
Although recommendations are made for the most common system types in the following
pages, there are actually over 1000 unique and useful jumper combinations available for a
wide variety of vehicles, installations and personal tastes. While this flexibility has obvious
advantages, too many choices can also be confusing. Therefore, it will be helpful to understand the function of each jumper group in order to tune the network more effectively:
TW-HP:
In addition to functioning as a high-pass filter, this section also provides the necessary
adjustments for proper integration with the midrange. The transition between these two
drivers in the frequency and time domains is essential to the total performance of a
multi-element system, as it has a direct effect upon imaging, staging, focus
and tonal balance. In real world installations, distance and angle of both drivers relative
to the listener, their proximity to each other, and certainly the vehicle's interior also exert
additional influence. In anticipation of this, variations of filter slope, Q, cut-off frequency
and resultant phase shift are provided so that "phase linkage" and flat summation can
be maintained. As a general reference, the layout and available filter types of the tweeter
high-pass section are provided below:

3rd Order:

TW LEVEL:
In general, this section provides precise level adjustment for optimum performance or
personal taste. However, it also allows for “tilting” of the filter frequency response in
order to compensate for the natural high frequency roll-off associated with off-axis listening angles. In other words, this jumper choice will have a direct effect on both Q and
cut-off frequency of the various filter combinations listed above. This effect can be seen
in the filter transfer function graphs for the various system types. If the TW-HP section is
set to bypass in favor of an electronic crossover, the off-axis feature will no longer function, but basic level adjustment will still be possible.
10
MID HP/LP:
As a selectable bandpass filter for the midrange, the net effect of this section is naturally
linked to the selections made in the tweeter high-pass and woofer low-pass sections.
Achieving the most phase coherent and flat summation possible requires controlling
the amount of inherent phase shift of each filter, and is directly related to the selection of
filter order, Q and cut-off frequency. Again, this relationship is also affected by the distance and angle of each driver relative to the listener and their proximity to each other.
Since the acoustic center of the midrange will be farther back than the tweeter in nearly
all applications, minimal delay is desirable in the midrange low-pass. Subsequently, this
filter is of low order, and leaves much of the adjustment capability for the mid/tweeter
transition to the tweeter high-pass section. For the midrange high-pass, higher order
configurations are used in most applications to achieve phase linkage with the woofer
(see WF-LP section). For general reference, the available midrange network configurations are listed below. In certain installations where positioning or placement necessitates level adjustment, a jumper is provided that boosts midrange output by approximately +2dB. As an additional note, either filter (high-pass or low-pass) may be bypassed independently for semi-active applications.

Jumper Group Function
WF-LP:
While functioning as a low-pass filter for the woofer, this section also provides a wide
degree of adjustments for optimizing performance and system integration. Since it is
often difficult to position the woofer and midrange close together or at equal distances,
it is critical to achieve phase linkage between them to avoid localization, image smear,
poor staging, etc. Additionally, vehicle interior dimensions are typically close to the wavelength of the woofer/midrange crossover region, so it may be necessary to minimize
overlap to reduce the chance of generating a complex canceling sound field or response aberrations. Therefore, a variety of higher order filter types and characteristics
are provided in this section, making it possible to link the two drivers in relative phase
for a smooth transition in many applications. Again, it is important to note that the selections made in both the WF-LP and MID-HP sections produce a net effect, and must be
set in such a way so as to work together. As a general reference, the available woofer
low-pass filter configurations are listed below.

SIGNAL LINK:
The signal link jumpers provide a parallel connection between the input sides of the
terminal blocks, eliminating the need for extra terminals or wiring when using a single or
dual input.
Caution:
These jumpers
must be removed accordingly when used in a bi-amp or tri-amp
configuration to prevent possible damage to amplifiers.

System Type 1
System Description
With all three drivers mounted close together and equidistant to the listening position,
this is surely the most favorable configuration for a component speaker system. Although such an installation may not often be practical in situations other than the demoboard, it is certainly possible given the custom fabrication techniques available today. In
anticipation this, a degree of tolerance is built into the settings described below for the
most likely cases, though some experimentation may be necessary if all conditions
cannot be met. If choosing to go beyond the recommended settings or utilizing the
network in a partially active mode, keep in mind that phase coherence and flat summation remains critical even in the idyllic flat baffle situation, as each driver type exhibits
unique phase and group delay characteristics.
