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#1StatusTM 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.
As with all AlpineF#1StatusTM products, it is the attention to the smallest details that truly brings out ultimate performance… or in a word, MicroDynamicsTM. 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:

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
r

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.
· Type-1A is the default setting of the network, and assumes essentially on- axis positioning and equal pathlength of all drivers relative to the listening position.

English

• Type-1B is for such cases where pathlength is nearly the same to all drivers, but where the mounting surface orientation creates a uniform but fairly extreme off-axis listening angle.

System Type 2
System Description
As one of the more common applications, this installation type is the most likely to be accommodated by factory speaker locations to some degree, thus requiring the least amount of custom fabrication. However, due to the mounting arrangement and surface orientation, it also results in significant differences in distance and angle of all three drivers relative to the listener. In order to optimize performance in this case, it especially critical to link each driver together in relative phase throughout the transitional crossover regions, while also taking into account the frequency response effects of the various off-axis listening angles of each driver. Two network configurations are provided for the most typical variations of this installation type, each employing specific phase correction and response compensation. Again, please note that the tuning of the settings below considers the best balance between driver and passenger listening positions, so all distances and angles are referenced to the nearest side. Also worth noting is the fact that the shorter near side pathlenths to the midrange and tweeter will result in more dramatic seating position bias than other installation types. While it is possible to adjust each network individually in order to specifically tune for one listening position, it will often be more beneficial to utilize basic time correction to correct for this left/right pathlength difference if available. In general though, a high tweeter location is thought to be advantageous for improving perceived height and width of the soundstage, as well as achieving a strong high frequency output level.
· Type-2A takes into account that all drivers are mounted more or less flush to the panel on a mostly flat vertical surface such as the door, thus presenting varying degrees of both axis and distance of each driver to the listener.
· Type-2B is the same as above, but assumes the woofer somewhat farther away than is typical. This will accommodate different vehicle types as well as kick panel mounting of the woofer.

Network Jumper Setting
Type-2A: For the tweeter in this case, 10 pathlength from the listening position is con- 0 sidered to be 85cm, at approximately 1520° off-axis. Located at a moderate vertical ­10 distance down from the tweeter and basi- ­20 cally flush to the panel, the midrange is 8.5cm farther away and presents a listening ­30 angle of about 40-50°. Due to the low door ­40 woofer location however, the listening angle
­50
for the woofer is close to 60° off-axis, with 20Hz 30Hz its acoustic center 8cm farther relative to the mid. For the tweeter/mid transition, a 3rd order high-pass and semi-1st order low-pass with increased level on the mid are engaged, resulting in a summation point of 4kHz. Optimum integration between the woofer and mid is then achieved with 4th order high-pass and low-pass at 700Hz.

System Type 3
System Description
Although the midrange and tweeter are mounted close together in this case, space limitations, aesthetics or practicality requires that the woofer be mounted separately. Utilizing the kick panel and door locations is the most common method, though it is certainly not the only one. What is most significant, is that by mounting the midrange and tweeter in close proximity with a minimized off-axis angle at the greatest distance possible, 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 in some installations, two basic configurations are provided to accommodate the most common cases. Keep in mind that the network tuning described below considers the best balance between driver and passenger listening positions, so all distances and angles are referenced to the nearest side.

English

• Type-3A assumes that both the midrange and tweeter are mounted close together in the same plane, and therefore relatively on-axis and equidistant to the listener.
• Type-3B takes into consideration that the tweeter and midrange are mounted basically flush to the panel with little or no build out. This results in both an off-axis condition and a difference in pathlength.

System Type 4
System Description
In this system type, some level of external signal processing is available, allowing use of the network in a partially active mode. Although speakers may be mounted in a wide variety locations in this case, it is recommended that traditional techniques be used regarding both positioning and placement.
Fully active systems have often been considered to be the most flexible, but they are certainly not the most effective or practical in all cases. While it is usually considered best to have individual channels of amplification for each driver, it may not always be appropriate to use the electronic crossover that is included with many amplifiers today. This can be especially true for systems where optimum placement or tuning is not possible, as it may be advantageous to use this network for its various phase correction and response compensation capabilities. Additionally, digital time correction can be a complimentary solution to correct for left/right seating position bias, while leaving the network in place to achieve phase linkage between the woofer, midrange and tweeter. The only situation where the network might not be used at all, is in a fully active system with individual channels of amplification, equalization and time correction available for each driver.
There are essentially three ways to use the network in a partially active mode:

1. Use all functions of the network appropriate for the installation type, but engage an electronic high-pass on the woofer for increased power handling (usually recommended in systems with subwoofers).
2. If only a limited number of channels or coarse adjustment of digital time correction is available, use it to compensate for basic left/right seating position bias while using the appropriate network setting to achieve phase linkage between individual drivers.
3. Bypass particular high-pass or low-pass section of the network in favor of an electronic crossover, still utilizing the phase and response adjustments of the others.

En général, cette section permet un réglage de niveau précis pour un résultat optimal ou le respect de goûts personnels. Cependant, elle permet également le “basculement” de la réponse de fréquence du filtre afin de compenser la pente naturelle de la haute fréquence liée aux angles d’écoute situés en dehors de l’axe principal. En d’autres mots, ce choix de cavalier aura un effet spécifique à la fois sur Q et la fréquence de coupure des différentes combinaisons de filtre montrées ci-dessus. Cet effet peut être observé dans les graphiques de fonction du transfert de filtre pour les différents types de système. Si la section TW-HP est réglée pour se court-circuiter en faveur d’un répartiteur électronique, la fonction hors-axe ne fonctionnera plus, mais le réglage de niveau de base sera toujours possible.

Fonction de groupe cavalier
WF-LP:
Lorsqu’elle fonctionne comme un filtre passe-bas pour le woofer, cette section offre également un grand degré de réglages pour l’optimisation des performances et de l’intégration du système. Puisqu’il est souvent difficile de placer le woofer et le hautparleur médial près l’un de l’autre ou à des distances égales, il est difficile d’obtenir une liaison de phase entre eux pour éviter la localisation, le marbrage d’image, la pauvreté de mise en scène, etc. De plus, les dimensions intérieures d’un véhicule sont généralement proches de la longueur d’onde de la zone de croisement du woofer /haut-parleur médial, et il peut donc être nécessaire de minimiser le chevauchement afin de réduire les risques de générer un champ acoustique d’élimination complexe ou des aberrations de réponse. C’est pourquoi une variété de types et de caractéristiques de filtre d’ordre plus élevé est fournie dans cette section, ce qui permet de lier les deux amplificateurs en phase relative pour assurer une transition douce dans de nombreuses applications. Encore une fois, il est important de remarquer que les sélections faites dans les sections WF-LP et MID-HP produisent un effet de réseau et doivent être réglées de telle sorte qu’elles fonctionnent ensemble. En guise de référence générale, les configurations du filtre passe-bas du woofer disponibles sont énumérées plus bas.
