The EXC Component Speaker System is the result of highly focused engineering effort.
Each element of the EXC system represents several advances in automotive speaker
technology. When the EXC project was initiated, the following goals were established:
EXC
•
•
•
•
•
High performance sound reproduction in the automotive environment.
Ease of installation
DESIGN
Superb ergonomics and visual appeal.
High output capability
Ability to "tailor" sound to each vehicle
Through extensive testing and development, the EXC system has been designed to
provide extremely consistent on and off-axis response in the automobile. Installation
flexibility and ergonomics are enhanced by the mounting versatility of both the EXC
midrange/woofer and the EXC tweeter. Finally, the high output capability and low
frequency extension of the EXC woofers are atypical of most drivers due to the
excursion capabilities of the EXC woofers and the steep crossover slopes of the EXC
system crossovers.
These efforts have resulted in an extremely flexible speaker system that performs
flawlessly in a variety of locations.
FEATURES
EXC Midrange / Woofer
The EXC woofers represent a departure from typical midrange/mid-bass drivers by
combining massive mid-bass and exceptionally smooth midrange.
• Non-resonant Glass resin basket has been designed specifically for extra long
excursion. This results in higher output and extended low frequency response.
• Non-resonant cone geometry yields smooth response and ultra-low distortion.
EXC Soft Dome Neodymium Tweeter
The EXC tweeter is an ultra-high performance 1" Neodymium tweeter designed to
deliver outstanding high frequency reproduction
• Fourth-generation Neodymium Magnetic Assembly providing performance comparable or
superior to tweeters three times the size
• A newly improved Textile Dome for a natural, smooth response to 20 kHz.
• Ferrofluid-immersed Voice Coil enhances heat dissipation
EXC Passive Crossover Network
The EXC Passive Crossover represents a new concept in crossover philosophy. The
EXC system crossover consists of high quality, multi-element components with two
switchable functions. A three-position switch controls the tweeter level and a two-
position switch controls the midrange presence. The combination of each allows for a
multitude of control options. Dual inputs allow for multi-channel amp operation of woofer
and tweeter circuits.
• 24 dB/octave Acoustic Summation Crossover Slopes for smooth response.
• Variable Tweeter and Midrange Controls for added flexibility.
• Dual Inputs for multi-amp operation and further flexibility.
• Dynamic Tweeter level Control allows for improved power handling and continuous output.
• Ultra-low DCR Inductors for minimal signal loss (High power Air-core type in woofer path).
• Mylar Film Capacitors to ensure low saturation and accuracy in the high frequencies.

LOCATION
AND
MOUNTING
The first step in a successful installation is thorough planning. Choose the location for
your speaker components carefully. Follow these suggestions to ensure proper imaging
and the best performance:
•
Select a location where each tweeter and midrange/woofer can be mounted close to
each other. A good rule of thumb is a maximum of one foot from midrange/woofer to
tweeter.
•
•
•
Choose a location that offers the least amount of sound obstruction.
Try to mount the components on the same plane.
Always check behind the chosen mounting locations to make sure that there are no
obstructions (e.g., trunk springs, gas tank, window track) or wires in the way, as well
as to make sure that there is ample support on which to mount the components.
INSTALLING
THE EXC
TWEETER
The EXC tweeter can be installed in a variety of ways: a simple yet elegant installation
cup is provided for flush mounting; or the tweeter may be easily disassembled for
custom applications, such as installation in vents, custom painting, or mounting behind a
factory grille. Hardware is provided for each mounting configuration.
For surface mounting, locate a flat mounting surface for the EXC tweeter. A direct "on--
axis" location is not necessary, as the EXC tweeter provides extraordinary "off-axis"
response.
Flush Mounting
1) Cut a 1 7/8" diameter hole through
the mounting surface. If the surface
is covered with cloth or carpet, be
careful not to tear or pull the
material. Sometimes it is a good
idea to peel the material away and
then trim it by hand.
2) Secure the cup in the mounting
cutout by using the spring clips and
screw provided. Slip the spring clips
through the bottom of the cup and
tighten the screw until the cup is
firmly seated. See Figure 1.
FIGURE 1
3) Once the cup is secure, mount the
tweeter into the cup making sure to
pass the tweeter wires through the
openings in the cup. The tweeter
will lock into the cup when turned
clockwise. See Figure 2.

1) Remove the tweeter's plastic backplate
by separating the plate from the tweeter
housing with your two thumbnails at one
of the terminal locations, gently prying
the two pieces until they snap apart.
See Figure 3.

MOUNTING
2) Mark the location in which you are going
to mount the tweeter using the supplied
template and drill holes for each of the
two wires. Also drill small "pilaf' holes for
the two mounting screws.

3) Mount the backplate with the two 1/2" flat
head screws. See Figure 4 below.
4) Feed the wires through the holes and
attach them to the speaker wires going
to the crossover. Position the tweeter
over the backplate and then simply snap
it back on. Be sure to feed the Red wire
through the (+) marked hole.

MOUNTING
2) Drill out the appropriate holes in the back
of the angle mount. Mark the location in
which you are going to mount the tweeter
using the supplied template and drill holes
for each of the two wires. Also drill small
"pilot" holes for the two mounting screws.
3) Mount the angle mount backplate with the
two1/2" flat head screws. See Figure 5.
4) Feed the wires through the holes and
attach them to the speaker wires going to

The EXC Midrange/Woofer can be mounted on the front or rear of a panel; gaskets are provided
for both options. The bolt-hole configuration will fit a variety of standard OEM patterns making it
ideal for direct replacement. Best performance is achieved when the speaker is securely mounted
to a door panel or rear deck. There should be no gaps between the speaker and the mounting
surface, as this will impair its low frequency performance. Be certain that both the panel and the
speaker are securely mounted to prevent unwanted vibration.
INSTALLING
THE EXC
MIDRANGE-
WOOFER
1. Mark the speaker location by using the template provided.
2. Cut the opening and debur the edges with a file.
3. Hold the speaker in place against the mounting surface and mark the mounting bolt holes.
4. Drill the appropriate size pilot holes for the screws provided.
5. Make all speaker connections prior to mounting the speaker to the panel.
6. Place the Exact woofer into the trim ring, make the speaker wire connections, then install
the speaker/trim ring assembly to the panel using the screws provided. Affix the grille.
7. When routing speaker cables to the driver, it is important to form a drip loop in the cable
below the level of the driver to keep water from reaching it. See Figure 6.

The EXC Passive Crossover can be mounted in virtually any location inside the vehicle.
Be sure not to mount the EXC system crossover outside the vehicle, or in a location
where it may be exposed to dirt or moisture (e.g., the engine compartment, inside a
wheel housing, inside a door, at the bottom of a leaky trunk).

Tweeter Attenuation
TWEETER
LEVEL
CONTROL
The EXC system has been designed to provide optimum sound in a variety of
installation locations. The provided crossover allows for three positions of tweeter level
control: HIGH, MED and LOW. The LOW position is useful for using the EXC system in
rear-fill applications. A switch under the clear plastic crossover cover sets one of the
three positions. See Figure 7.
Midrange Attenuation
MIDRANGE
LEVEL
CONTROL
The provided crossover also allows for two positions of midrange level control. A switch
under the clear plastic crossover cover sets one of the two positions - MIDRANGE
PRESENCE -- ON/OFF. The ON position provides increased midrange, a feature useful
for adjusting midrange vocal presence. See Figure 7.
Tweeter Protection Activation
DYNAMIC
TWEETER
LEVEL
Under high power/high volume conditions, the dynamic tweeter level control (DTLC)
circuit may activate. The purpose of DTLC is to prevent failure of the tweeter by reducing
its output when necessary. Upon activation of the DTLC circuit, there will be an audible
decrease in high frequency output as well as a visual indication from the DTLC light bulb
(see Figure 7). The circuit is self-resetting -- if the DTLC activates, turn the volume down
and normal operation will resume momentarily.

EXC System Wiring Diagram
WIRING
Figure 8 shows a diagram illustrating the wiring of the EXC Component Speaker
System. It is important to make sure that all connections are in phase; that is positive (+)
is connected to positive (+), and negative (-) is connected to negative (-), since an out-of-
phase connection will cause a dislocated image and low bass output. We suggest using
a minimum of 16 gauge (ideally 12 gauge) premium cable. The connectors provided with
this system will accommodate wire from 12 gauge to 16 gauge.

NOTES ON
BI-AMPING
Bi-Wiring
The EXC component system includes the
EXC passive crossover which is optimized
for the speakers. The EXC crossover
allows for dual amp inputs. See Figure 9.
This feature allows for a 4 channel
amplifier or two 2 channel amplifiers to
power the four individual drivers of an EXC
.6 system. The benefit of this is added
dynamics and level setting flexibility. A
head unit's fader control could be used as
a tweeter level control. (See note about
crossover modification for bi-amping.)

Bi-Amping
NOTES ON
BI-AMPING
(CONTD.)
True bi-amping can also be accomplished with an
external electronic crossover. See Figure 10.
Even greater dynamics can be realized with
bandwidth-limited amplifiers. If your decide to bi-
amp, please follow the recommendations below:
1) Use at least a 12dB/octave high pass filter no
higher than 1500 Hz on the tweeters.
2) Use at least a 12dB/octave low pass filter no
lower than 6000 Hz on the woofers.
This "staggered" active arrangement allows one
full octave of bandwidth between the amp's active
range and the speaker's passive range. This
stagger allows the purpose designed passive
network to operate as intended. You will gain the
benefit of dedicated amplifiers and retain the
sound quality designed into the passive crossover.
