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.

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-Z15M 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. 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 250 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:

Although essentially a selectable high-pass filter, this section provides the major part of the phase correction and response compensation of the network. By altering the slope, Q, cut-off frequency and phase shift of the high-pass filter, it is possible to create “phase linkage” with the woofer. This proper summation in the frequency and time domains is what produces the seamless blend necessary for optimum imaging, staging, focus and tonal balance in a multi-element system.

These relationships are affected by the distance and angle of both drivers relative to the listener, their proximity to each other, and certainly the vehicle's interior as well. While it is beyond the scope of this manual to describe each potential network combination in detail, the following filter types are possible for the high-pass section of the network:

TW PHASE:

This jumper group provides a means by which the tweeter connection can easily be reversed. By flipping the tweeter polarity “in” or “out” of phase ( 0^ or 180^ ), it is possible to achieve proper phase linkage for a wider variety of applications.

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, tweeter level jumper selection will have a specific effect upon both Q and cut-off frequency of each high-pass filter configuration. 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.

WF-LP:

In addition to functioning as a selectable low-pass filter, this section also provides part of the phase correction and response compensation of the network. By shifting the phase appropriately within the crossover region, it is possible to achieve “phase linkage” with the tweeter, producing a seamless blend or transition between the two drivers. This relationship is affected by the distance and angle of both drivers relative to the listener, but also by their proximity to each other. Since in this case, most of the manipulation of the overlapping region is being done in the tweeter high-pass filter, less variation of the woofer low-pass is necessary. Subsequently there are basically two possibilities for the LPF:

• LP1 = low Q 1^st - 2^nd order roll off (starting at 6dB/oct. ending at 9dB/oct.)
• LP2 = semi- 1^st Order (shallow 3-4dB/oct. roll off)

$$ \mathrm{C} 3 = 3 3 \mu \mathrm{F} $$

$$ \mathrm{L} 4 = 0. 3 9 \mathrm{mH} $$

SIGNAL LINK:

The signal link jumpers provide a parallel connection between the input sides of the two terminal blocks, allowing a single input connection to be made without the use of extra terminals or wiring.

Caution:

These jumpers must be removed when used in a bi-amp configuration to prevent possible damage to amplifiers.

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.

- Type-1B is optimized for installations where build out for better on-axis positioning is possible, and the tweeter is mounted vertical over the woofer.

- Type-1C is for particular cases where flat to the surface mounting is required, and the tweeter is mounted over the woofer necessitating some delay for proper alignment of the two drivers.

Network Jumper Setting

Type-1A: Pathlength to the listening position is considered to be equal in this case, with relative on-axis positioning of both drivers. Phase linkage accomplished with a relatively high Q 3 ^rd Order high-pass filter on the tweeter, resulting in a 12dB/oct. roll-off at the starting point that steepens to 18dB/oct. below 2kHz. The woofer low-pass is a semi-1 ^st Order with a very gradual slope of 3-4dB/oct. As a result, the acoustic crossover point between the two drivers is 2.8kHz.

Notes:

• Highlighted tweeter level jumpers are the recommended settings for each configuration, but some user adjustment may be desirable.
• Transfer function simulations only illustrate the effect of the filter upon the input signal, and therefore do not represent the actual frequency response of the system.
• If separate channels of amplification are used (bi-wire mode), the appropriate signal link jumpers must be removed.

Network Jumper Setting

Type-1A (option): While the mounting configuration is the same as Type-1A, this network setting provides a variation for particular cases where either personal taste or vehicle acoustics requires a more gradual slope on the tweeter. In this case, the tweeter high-pass is a very low Q 2 ^nd Order, with a roll-off starting at 6dB/oct. and ending at 12dB/oct. To achieve phase linkage between the two drivers, the tweeter phase is inverted by reversing its physical connection within the network. Essentially, the parallel coil eliminates the influence of the resonance frequency, and the tweeter rolls off 12dB/oct. below 1kHz. The woofer low-pass is a semi-1 ^st Order with a very gradual slope of 3-4dB/oct. The resultant acoustic crossover point between the two drivers is 2.2kHz.

Network Jumper Setting

Type-1B: In some cases it may be possible or desirable to mount both drivers close together with on-axis positioning, but not quite at same distance to the listening position. In general, it is assumed that the tweeter is the closer of the two, as would be the case if it is mounted over the woofer. While there will obviously be some tolerance associated with different vehicles and installation methods, this difference is considered to be approx. 12cm. Phase linkage is accomplished by inverting the tweeter and using a slightly lower Q 3 ^rd Order high-pass than in Type-1A, combined with a low Q quasi-2 ^nd Order low-pass on the woofer. This results in an acoustic crossover point of 2.2kHz.

Network Jumper Setting

Type-1C: Even if close proximity of the two drivers can be achieved, it may not be possible to build out the mounting angles for on-axis or equidistant positioning relative to the listening position. In this particular case, both drivers are considered to be mounted basically flat to the panel, with the tweeter located over the woofer. This situation results in a relative delay of the woofer by approx. 10cm. For phase linkage in the crossover region, it is then desirable to minimize the phase shift on the woofer, and then match that to a somewhat moderate phase shift on the tweeter. This is achieved by applying a very shallow semi- 1^st order low pass on the woofer, and a relatively low Q 3^rd Order high-pass with inverted connection on the tweeter. The resultant acoustic crossover point between the two drivers is 2.15kHz.

System Description

In this system type, both the woofer and tweeter are mounted apart at different distances and angles relative to the listening position, with the tweeter as the closest driver. While this type of installation is undoubtedly the most common today, some may not consider it to be an ideal situation for imaging due to the large difference in distance. 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. In typical OEM woofer locations, the woofer is nearly always at an extreme listening angle, while the tweeter is only slightly off-axis. The woofer axis becomes more extreme the farther away it is, if there is no build out of the mounting angle. It just so happens that the same high-pass and low-pass configurations work for the two most typical installation types, only requiring a slight change in tweeter level to more properly match woofer output. It is important to 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.

- Type-2A is considered to be the most common installation type, as the woofer is typically mounted low in the door in the factory position.

- Type-2B is essentially 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, pathlength from the listening position is considered to be 85cm, at approximately 10-15° off-axis. Due to the low door location however, the listening angle for the woofer is close to 50° off-axis, resulting in a relative delay of 18cm. Therefore, minimal delay in the woofer is achieved by employing a semi-1 ^st Order 3dB/oct. low-pass. This integrates well with a steep 4 ^th Order high-pass on the tweeter, for a resultant acoustic crossover point of 2.15kHz.

Network Jumper Setting

Type-2B: Tweeter distance and angle are the same as above, but the woofer is located farther forward. This results in a woofer listening angle of approximately 70^ off-axis, with a relative delay of 36cm. Again, minimal delay in the woofer is achieved by employing a semi- 1^st Order 3dB/oct. low-pass, which still integrates nicely with a 4^th Order high-pass on the tweeter as long as some additional level attenuation is applied. The resultant acoustic crossover point is 2.05kHz.

System Type 3

System Description

In this system type, the woofer and tweeter are mounted close together on the dashboard, rear deck, or other surface that presents an oblique angle to the listener. In the particular case of center channel usage, customized mounting is almost always necessary. It should be noted that since it is impossible to anticipate every conceivable installation style, some experimentation may be necessary beyond the recommended settings. In rear deck or similar applications, the network tuning considers the best balance between driver and passenger listening positions, so all distances and angles are referenced to the nearest side.

- Type-3A is considered to be a fairly close and central location with a sloping surface, resulting in an off-axis condition of both drivers relative to the listener. Additionally, due to the vertical configuration, the tweeter is the farthest of the two.

- Type-3B assumes mounting on a flat surface at some distance, with both drivers approximately equidistant relative to the listening position. The significant difference from Type-3A is that the pathlengths of each driver are essentially equal, and the flat surface presents a more extreme listening angle.

Network Jumper Setting

Type-3A: Despite the fact that both drivers are mounted in the same plane and in close proximity, their orientation results in the acoustic center of the tweeter being farther away. Both drivers are considered to be 45^ off-axis at an average distance of approximately 1 meter. In this case, a medium Q 3^rd Order high-pass filter is employed in conjunction with an inverted connection to the tweeter. Proper integration between the two is then achieved with a low Q quasi- 2^nd Order low-pass on the woofer, resulting in an acoustic crossover point of 2.2kHz.

Network Jumper Setting

Type-3B: In positions where the component set is farther away on a flat surface, the listening angle becomes quite extreme. In this case, the mounting position is considered to present an approximate angle of 60-70° off-axis angle, at a distance of 1.2 meters to both drivers relative to the listener. Phase linkage is accomplished with a relatively high Q 3 ^rd Order high-pass filter on the tweeter, resulting in a 12dB/oct. roll-off at the starting point that steepens to 18dB/oct. below 2kHz. The woofer low pass is a semi-1 ^st Order with a very gradual slope of 3-4dB/ oct. As a result, the acoustic crossover point between the two drivers is 2.3kHz.

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 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 either the high-pass or low-pass section of the network in favor of an electronic crossover, still utilizing the phase and response adjustments of the other.
