OWNER’S MANUAL
EXACT 6.2
DESIGN
The EXACT6.2 Coaxial Speaker System is the result of highly focused engineering effort. Each
element of the EXACT6.2 represents several advances in automotive speaker technology.
When the project was initiated, the following goals were established:
· High performance sound reproduction in the automotive environment
· Ease of installation
· Superb ergonomics and visual appeal
· High output capability
· Ability to “tailor” sound to each vehicle
Through extensive testing and development, the EXACT6.2 has been designed to provide
extremely consistent on and off-axis response in the automobile. The high output capability and
1
low frequency extension of the EXACT6.2 are atypical of 6 /2” drivers due to the excursion
capabilities of the EXACT 6 and the steep crossover slopes of the EXACT6.2X.
These efforts have resulted in an extremely flexible speaker system that performs flawlessly in a
variety of installation locations in virtually any vehicle.
FEATURES
EXACT6.2 Midrange / Woofer
The EXACT6.2 represents a departure from typical midrange/midbass drivers by combining
massive midbass and exceptionally smooth midrange.
· Copper Inductance Cap for smoother midrange response and lower distortion
· Natural Fiber Cone designed for optimum rigidity and damping with minimal “coloration.”
25mm Soft Dome Neodymium Tweeter
The EXACT6.2's tweeter is an ultra-high performance 25mm 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.
· Specially-treated Textile Dome for a natural, smooth response to 20 kHz.
· Ferrofluid-immersed Voice Coil enhances heat dissipation
EXACT6.2X Passive Crossover Network
The EXACT6.2X Passive Crossover represents a new concept in crossover philosophy. The
EXACT6.2X crossover consists of high quality, multi-element components with two switchable
functions. First is a three position tweeter level control. Second, is a two position midrange
“presence” control. 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 frequency 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 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:
· Choose a location that offers the least obstruction of sound to your ears.
· Always check behind the chosen mounting locations to make sure that there are no
obstructions (e.g., trunk springs, gas tank, window tracks) or wires in the way, as well
as to make sure that there is ample support on which to mount the components.

INSTALLING
THEEXACT6.2
DRIVER
The EXACT6.2 Driver 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
American, Asian and European 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.
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 hole for the screws provided.
5) Make all speaker connections prior to mounting the speaker to the panel.
6) Place the EXACT6.2 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 EXACT driver, it is important to form a drip loop
in the cable below the level of the speaker to keep water from reaching it. See

MOUNTING
THE
EXACT6.2X
CROSSOVER
The EXACT6.2X Passive Crossover can be mounted in virtually any location inside the
vehicle. Be sure not to mount the EXACT6.2X 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
LEVEL
CONTROL
Tweeter Attenuation
The EXACT6.2 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 EXACT6.2 in
rear-fill applications. A switch under the clear plastic crossover cover sets one of the
three positions. See Figure 2.
MIDRANGE
LEVEL
CONTROL
Midrange Attenuation
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 2.

Tweeter Protection Activation
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. You will notice a decrease in high frequency
output and the light bulb on the crossover board will light up (see Figure 3). The circuit
is self-resetting -- if the DTLC activates, turn the volume down and normal operation will
resume in a few minutes.

WIRING
EXACT6.2 Wiring Diagram
Figure 4 shows a diagram illustrating the wiring of the EXACT6.2 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. The
provided cable harness is color coordinated to aid proper connection of crossovers to
speakers; wire colors should match speaker terminal tab colors. For amplifier to
crossover connection, 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.

CROSSOVER FOR ANY
The EXACT6.2 system includes the
EXACT6.2X passive crossover which
is optimized for the speakers. The
EXACT6.2X allows for dual amp
inputs. See Figure 5.
BI-AMP OR BI-WIRING APPLICATION
This feature allows for a 4 channel
amplifier or two 2 channel amps to
power the four individual drivers of an
EXACT6.2 system. The benefit of this
is added dynamics and level setting
flexibility. For example, a head unit’s
fader control could be used as a
tweeter level control.

True
bi-amping can also be
accomplished with an external electronic
crossover. See Figure 6. Even greater
dynamics can be realized with bandwidth
limited amplifiers. If you decide to bi-amp,
please follow the recommendations
below :
BI-AMP OR BI-WIRING APPLICATION
1)Use at least a 12dB/octave high pass
filter no higher than 1500 Hz on the
tweeters.
2)Use at least a 12 dB/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
