Crossover Networks
The McIntosh Woofer/Midrange and Tweeter Drivers offer
extremely smooth frequency response, low distortion, high
sensitivity and high power handling capability. When these
Drivers are combined with other McIntosh Vehicle Compo-
nents, you will enjoy sonically accurate music reproduction
in your vehicle which meets McIntosh traditional standards
of excellence.

Performance Features
• Patented Technology
The widely acclaimed McIntosh LD/HP® (Low Distortion/
High Performance) Magnetic Circuit Design1 dramatically
reduces harmonic distortion.

• Special Woofer/Midrange Driver Design
The Woofer/Midrange Driver utilizes injection molded
Black Polypropylene Cones and NBR Rubber Surrounds to
provide stable performance in the demanding vehicle envi-
ronment. Its Die Cast Aluminum Frame ensures excellent
rigidity, dimensional integrity and lasting value.
• Special Tweeter Driver Design
The Tweeter Driver utilizes a black, Soft Textile Dome for
smooth response and greater sensitivity. It also incorporates
a Neodymium Magnet which has the highest flux energy
that is currently available. The Tweeter Design utilizes both
Tinsel Voice Coil Leads and Magnetic Fluid for improved
repetitive high peak power handling capability. Pre-at-
tached leads simplify connection to the Crossover Net-
work.

• Low Distortion Crossover
The Crossover utilizes capacitors with low ESR, coils with
low DCR and a 2nd Order Crossover Circuit Design for
smooth frequency response. The Crossover allows for three
different high frequency response curves to compensate for
various automotive environments. It incorporates a self re-
setting Poly-Switch to provide automatic overload protec-
tion to the Loudspeaker System. The Crossover Enclosures
are made from a high temperature ABS material capable of
withstanding the demanding temperature variations of a
vehicle environment.

Installation
It is recommended that a qualified professional install all
McIntosh Sound System Products. McIntosh Woofer/
Midrange Drivers, Tweeters and Crossover Networks
should be used in conjunction with McIntosh Subwoofers
and McIntosh Electronics to achieve the best possible per-
formance. McIntosh Subwoofers are designed to operate in
the bass frequency range below 120Hz and need not be
physically close to Midrange and Tweeter Loudspeakers in
order to maintain good imaging and system frequency bal-
ance. Another consideration in choosing the location for
the Loudspeaker Drivers and Crossover is to mount them
away from areas in the vehicle that might have high mois-
ture and temperature.
5. Place the wide foam ring gasket on the back side of the
plastic mounting ring that will contact the vehicle
panel or enclosure.
6. Carefully insert the Loudspeaker and mounting ring
assembly into the cutout. Secure the assembly by in-
serting four of the #8 x 1 inch supplied Sheet Metal
Screws, through the driver holes, the plastic mounting
ring holes and into the spring clip fasteners previously
installed over the mounting holes.
7. Press the metal grille cover into the speaker mounting
ring.
Mounting the Tweeter
Mounting the Woofer/Midrange
1. Cut a hole into the mounting surface using the supplied
template and then insert the Tweeter Leads into the just
cut opening. Refer to figure 2.
1. Using the enclosed template as a guide, mark and drill
the four pilot holes
for the mounting
Note: If the mounting surface opening is made too large the
Tweeter Locking Tabs will be unable to secure the
Tweeter to the mounting surface. The minimum
mounting surface thickness is 1/16 of an inch. If the
Tweeter Leads will not be accessible after inserting
them into the mounting opening, then proceed to
pages 8 and 9 for connection details before
screws. Drill the
mounting holes with
an appropriate size
drill bit.
2. Cut out the marked
circle in the tem-
performing the following step.
2. Compress the Locking Tabs as the Tweeter is inserted
into the mounting surface.
plate, and using it as
a guide, mark and
cutout the circular
hole for the Loud-
speaker in the ve-
hicle panel or suit-
able enclosure.
Note: If it should become necessary to remove the Tweeter
from the mounting surface, compress the Locking
Tabs at the rear of the Tweeter Magnet Assembly and
then push forward on the center of the magnet to
extract the Tweeter.
3. Place the narrow
foam ring gasket in
the matching groove

ing ring. Refer to

Installation
Mounting the Crossover
When selecting a Crossover mounting location, make sure
there is adequate room for ventilation (there are openings
on both sides of the Cross-
Mounting Screw Locations
over) and for making con-
nections to it. Use the sup-
plied screws for mounting
the Crossover to the vehicle.
1. Using the Crossover as
a template, mark the
two locations to drill
holes in the mounting
surface for the Cross-
over mounting screws.
Drill two holes with an
appropriate size drill bit.
Refer to figure 3.
2. Secure the Crossover to
the mounting surface
with the two #6 x 7/8
inch supplied Sheet
Metal Screws. Refer to
figure 4.

How to Connect a Two Way System
How to Connect a Two Way System
1. Press the connector ends of the supplied Woofer/
Midrange Red/Black cables onto the matching Woofer/
Midrange connecting lugs.
2. Attach the other ends of the two Red/Black Woofer/
Midrange cables to the Crossover Network WOOFER
OUTPUT Terminals. The Black wire connects to a MI-
NUS (-) Terminal and the Red wire to a PLUS (+) Ter-
minal.
3. Attach the connector ends of the supplied Red/Black
Tweeter Cables to the Tweeter Leads with connectors,
matching the color of the cables.
4. Attach the other ends of the two Red/Black Tweeter
Cables to the Crossover Network Tweeter Terminals.
The Black wire connects to a MINUS (-) Terminal and
the Red wire to the (0) POSITIVE Terminal.
Note: There are two additional Tweeter Positive Terminal
Connections (-3dB and -6dB) that allow for a reduction
in High Frequency Output to match the Sound System
Environment. Connect the Tweeter Positive (Red) Cable
to the -3dB or -6dB Positive Tweeter Output Terminal
that produces the preferred sound.
5. Connect the MINUS (-) OUTPUT of a McIntosh
Power Amplifier to the Crossover Network MINUS
INPUT Terminal and the PLUS (+) OUTPUT to the
Crossover Network PLUS (+) INPUT Terminal.
