Congratulations on your purchase of Blaupunkt’s
ProComponent
speakers! We at Blaupunkt feel
that these components are of the highest value available on the market today.
reliability, and installation flexibility is unequaled. Unlike radios and The performance,
amplifiers, speaker technology is more evolutionary than
revolutionary.
Incremental improvements are usually implemented with materials
change or minor design. Using Blaupunkt’s EXP Extended Pole Design
we are able to make substantial jumps in linear excursion and power
handling.
KEY COMPONENT FEATURES
The
ProComponent
sets offer tremendous
performance because of well thought out designs
focusing on performance and ease of installation.
Key
features include:

Very high power handling and low distortion for
the woofer due to the Extended Pole design.
High power handling for the tweeter through the
use of Neodymium magnets and a circuit-breaker
type “poly-switch” that opens the circuit to the
tweeter if over- driven.
Resin-laminated woofer cones to maintain rigidity
and resistance to moisture.
Easy installation via multiple mounting systems
for the tweeter.
12 dB/Octave linear phase crossovers
Color and mechanically “keyed” wiring to ensure
proper phase and reliable connections.
High efficiency
EXTENDED POLE DESIGN
In a conventional flush type pole piece the
asymmetrical flux distribution through the voice coil
prevents linear motion throughout the voice coil
travel.
The EXP design creates a symmetric magnetic field
resulting in longer linear travel of the voice coil which
yields lower distortion. Also, there is additional
control at the excursion limits thus offering higher
power handling. The music can now play louder,
longer, and with less risk in burning out your
woofers.

conventional flush type pole.
Because of the longer linear travel, power
handling and tonal quality are improved
dramatically.

We recommend you have your Blaupunkt speakers professionally installed but the installation
process is often so easy that the average consumer can make a successful installation with little
trouble. BUT, great care must be taken to ensure the safety of the installer and the vehicle. To
ensure such safety you should do the following:
1.
2.
3.
4.
5.
READ THE MANUAL! Understand the product and installation before beginning.
WEAR SAFETY GOGGLES!
PROTECT THE VEHICLE! Always disconnect the negative battery cable before starting any
installation work. This prevents high current shorts (i.e., potential fires)
VERIFY AN UNOBSTRUCTED INSTALL! Before cutting any trim components or drilling
holes, make sure there are no electrical wires, fuel or fluid lines, or structural metal members
hidden from view.
DO
NOT LISTEN AT HIGH LEVELS FOR PROLONGED PERIODS OF TIME! If connected to
25 watt amplifiers or higher, most car speakers in this performance level can cause permanent
hearing loss if listened to over several hours at maximum power.
Before ripping apart the interior of your beautiful new car you need some basic installation
knowledge and skill with common hand and power tools.
1.
2.
3.
4.
CHECK YOUR PARTS! Completely empty the box ensuring all parts are accounted for
and_
you have a clear visual understanding of the components.
GIVE YOURSELF
LOTS OF TIME!
Back-tracking to find problems after the installation can
often be avoided by moving slowly and carefully through the installation process.
READ THIS MANUAL! Read
aJ
of this manual to ensure an optimum performance and
reliability.
TAKE CARE
IN DISASSEMBLING THE VEHICLE!
Every manufacturer uses slightly different
construction
mqthods.
Take special care in removing trim and door panels since they often
use unique screws or snap fasteners.
For most installations, simple hand tools are adequate if replacing the factory speakers. If the
factory locations are not used power tools for drilling and cutting will likely be needed. A good
starting list is the following:
Marking pen and starting punch
Tape measure or ruler
Phillips and flat blade screwdrivers (small and medium sizes)
Wire cutters, and wire strippers, and electrical tape
Standard size vice-style pliers and needle nosed pliers
Light duty trim type pry bar
Cutting shears or nibbling tool (for cutting metal)
Crimping pliers and appropriate crimp-on spade terminals
Power drill with appropriate
sized drill bits
(118”
and
114”
as a start)

SOUND QUALITY
.A good audio system will faithfully reproduce the original recording by offering accurate
frequency response
and staging. Good frequency response reproduces high tones such as
symbols, through human voices and most instruments, and down to the very low tones from
synthesizers and drums. Frequency response includes timbre (the accurate replication of an
instrument), linearity (the tonal quality is the same regardless of volume level), and
c/&v
(lack
of distortion of the original signal). Blaupunkt speakers address these properties by having a very
smooth frequency response with low distortion levels.
Good staging offers the illusion of a stage upon which players are located and it has a sense of
height, width, and depth.
Imaging
is a sound system’s ability to correctly place the instruments
on the imaginary stage. Again, the Blaupunkt speakers excel here due to angled tweeter
mounting and smooth off-axis frequency response ensuring accurate reproduction.
LOUDNESS
It is fairly easy to build a sound system that plays loud but has very poor tonal accuracy. This is
done by simply placing lots of amplifiers and subwoofers in a car without attention to midrange
and high frequency speakers and ignoring their positioning. But, with some basic attention to
design, a loud system can also play accurately. In most vehicles, 50 watts per satellite speaker
(midrange/tweeter) and 100 watts into 2 subwoofers will provide nearly 120 decibels across the
audio spectrum of
20-20,000
Hz. This is the threshold of instantaneous permanent hearing loss
so it is useless (and dangerous) to add much more than 400 watts of system power.
MOUNTING SPEAKERS IN BOXES
We often receive calls from people wanting
to install their speakers into custom made
boxes. We whole
heattedly
support this
concept since the box provides an acoustical
“air-spring” for the woofer thus lowering
distortion and increasing power handling
compared to that of a free-air installation in a
car door.
These volumes are dictated by the speaker’s
“Thiele-Small” parameters which are noted in
the TECHNICAL SPECIFICATIONS section
of this manual. Since the
“Qts”
values are all
around 0.70 for this family of speakers, a
sealed box is the ONLY recommended
enclosure design. It must be understood that
a supplementary subwoofer is needed for
music below 100 Hz. Please note the
attached table for recommended box
volumes and dimensions
for
best
performance.

WHAT IS SYSTEM ARCHITECTURE?
System architecture is simply the design strategy
used
to assemble the radio, speakers, and any
additional amplifiers in order to maximize the overall system performance. Is the system two-way
or three-way? Are the crossovers passive or active? Are the amplifiers being operated in bridge
mode or stereo mode? All of these questions are answered in the outline diagram of the system.
A completely passive system can often sound as good as a completely active one if care is taken
in the component choice, speaker location choice, and the final installation.
Rarely is a 4x20 watt receiver and four coaxial speakers going to provide an impressive
performance. By moving to some good component speakers for the mids and highs (“satellite
speakers”) and adding a separate subwooofer speaker, overall performance is areatlv improved.
Noted below are a couple of popular
“satellife/subwoofer
systems that can tremendously
improve the performance but with reasonable cost and complexity.
ADD-ON COMPONENTSlSUBWOOFERS
Changing to component speakers for the mids
and highs greatly improves the tonal quality
and imaging over simple factory speaker
installations. In most cases, the factory radio
with its 4x20 watts is adequate for these
components. Also, the factory radio may be
installed in
a
cosmetically non-removable
fashion so this approach will solve many
installation problems.
Even with the addition of the component
speakers the sonic “impact” of a system is
often dictated by the low frequency response.
By adding a subwoofer and a basic 100 watt
amplifier the low
end
performance can now
offer the complementary ‘wow” effect of the
bass to the sonic accuracy of the component
speakers.
MULTI-CHANNEL
I
HIGH POWER
Moving up to a 4x50 watt satellite channel
amplifier powering four sets of components
and a 2x100 watt subwoofer amplifier
powering 2 subwoofers can offer stunning
performance!
The increase in amplifier power helps reduce
“clipping” which yields a “cracking” type of
sound which can damage nearly any speaker
over time. The tonal accuracy of the system is
also often improved because the amplifiers
are no longer strained at high listening levels.

MOUNTING COMPONENT SPEAKERS
The prime objectives of component speaker mounting are:
q
q
q
n
q
Positioning the speakers correctly
Mounting them to a solid surface
Making sure there are no air leaks between the front and back of the woofer cone
Protecting the speakers
Ensuring the wiring is correct
The lower the frequencies a speaker reproduces, the more solid it’s mounting surface must be.
This is necessary because a vibrating panel winds up acting like another loudspeaker and
introduces its own sound into the car. This secondary sound can severely degrade the sound of
the music yielding a “muffled” or “howling” sound at certain listening‘levels. A good air seal
isolating the sound from the back of the speaker from the front wave sound is critical. Lack of a
good air seal reduces the bass response and often creates a “hollow” sound from the woofer.
The tweeter’s mounting is not nearly so critical since it does not require a rear air seal and it
vibrates very little.
WIRING
Your
ProComponent
series speakers have
crossovers with wires which are clearly
marked regarding input (RED), tweeter output
(YELLOW), and the woofer output (GREEN).
Proper electrical phasing is maintained by
electrically “keyed” terminals using narrow
and wide spade terminals.
The crossover network is optimized for use
with these tweeters. If you prefer an active
crossover network, the lowest crossover point
should be 4.0
kHz
and with 12 dB/octave
high-pass.
Speaker wiring should be isolated from the
electrical system of the car and routed away
from any factory systems to avoid potential
noise pickup. If installing these speakers in
combination with other speakers make sure
that the combined impedances cannot
damage the amplifier or radio.

If the signal is heavily distorted or the music occasionally drops out check for short circuits of
wires to other wires or to the chassis of the car.
If nothing is heard at all but the power lights come on, check all connections between the radio
and speaker.
If the radio or amp does not turn on at all, contact your Blaupunkt dealer for help or the
Blaupunkt Technical support at l-800-266-2528.

INSTALLING THE WOOFERS IN FACTORY LOCATIONS
Most of today’s newer cars have speaker grilles which blend in aesthetically with the interior of the
car. The grille is usually held in with small screws or spring clips. To remove a clipped on grille,
gently
pry
up on the side with a flat blade screwdriver. (Some grilles are an integral part of the
door such that the entire door panel must be removed to expose the speaker.) Once the factory
speaker is exposed, remove the hardware and replace the factory unit with the new Blaupunkt
unit.
INSTALLING THE WOOFERS IN NON-FACTORY LOCATIONS
If you choose to install your new Blaupunkt speakers in locations other than the factory locations
make certain the new location is clear of obstructions in front of (e.g., armrests, window cranks)
and behind the speaker (e.g., door wiring, sheet metal).
Once the location is chosen, carefully cut the hole (using the cutout sizes at the back of the
manual), install the crossover in a convenient location, route and connect all wires, mount the
speaker, install the grille, and reinstall any panels and/or factory components.
DOOR MOUNTING
Door locations are most often favored because
of the tonal quality and imaging advantages
-
they provide compared to the typical dash
locations. Unfortunately the woofer is forced
into the very bottom of most doors because of
space constraints.
This low woofer installation creates a dilemma
because the tweeter should be kept close to
the woofer to maintain a unified sound field but
this often places the tweeter firing into the legs
of the passengers therefore high frequencies
are lost. If the tweeter is too high (at the top of
the door) the listener is overwhelmed with high
frequencies and the
left/right
balance is
damaged; therefore accurate imaging is lost.
Optimally, a balance must be achieved with
location which can often be found with the
tweeter just above knee
Ieve!
in most
automobiles. This will provide good frequency
response and imaging
REAR DECK MOUNTING
Rear
deck or sail panel installations are easily
accommodated with these speakers since the
woofers can often drop into factory holes or
may require a simple adaptor plate which can
be purchased or formed from wood.
The surface mount tweeter assembly does not
require any significant holes so a factory look
can be maintained in most cases.
.

The biggest advantage of component speakers is their ability, when properly installed, to provide
a tonally accurate sound with a wide sound stage but pinpoint localization of performers. The
largest impact over this sound stage is provided by the tweeter location and mounting angle. To
determine this optimal location and angle we recommend a simple experiment.
1.
Complete all of the installation except for the tweeters
(i.e,
woofers, crossover, and wiring).
2. Have a friend sit in the passenger’s seat while you sit in the driver’s seat, each holding a
tweeter up to the door.
3. With music having good high frequency content, move the tweeters around listening for the
best high frequency response yet maintaining a good left/right acoustical balance in the car.
Mounting the tweeters mid level and as far forward in the door panel is often the best
acoustical location in most cars. In most cases, the preferred location usually has the
tweeters facing the opposite occupant in the car.
The tweeter can now be mounted in one of the following four methods.
FLUSH MOUNT
This mount looks as though it is styled into the car. The
listeners are still slightly off-axis from the tweeter so high
frequency response suffers slightly.
A hole must be drilled to accommodate the flush cup. A
screw run in from the back and through the spring clip is
necessary to ensure a solid lifetime fit.
ANGLE FLUSH MOUNT
Acoustically and aesthetically, this is the BEST mounting
system. The tweeter is angled at the opposite occupant in the
car.
Like the flush cup, a hole must be drilled to accommodate the
cup. The spring clip is attached with the screw as shown.
SURFACE MOUNT
This method is used in installations where room is not
available behind the tweeter to drill a mounting hole for a flush
type
cup.
For this mounting method, a hole is drilled for both the wires
and mounting screw. A rear spring clip is not necessary but a
small backing washer is recommended to ensure that the
screw will not pull through the door panel over time.
ANGLE SURFACE MOUNT
Angling the tweeter puts the acoustical output of the tweeter
pointing ‘more at the listeners which give better high frequency
response.
Like the flat surface mount above, holes must be drilled for
the wires and screw. This mount is unique since the
Cup
is
mounted to the panel with the bolt 8 nut, and the tweeter is
then snaooed to the cup.
