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.

The extended pole design offers a longer

symmetrical magnetic field compared to a

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:

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.

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.

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

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

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

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

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:

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.

SYSTEM TEST

‘Rveeter

From

Redb

Anwli~

Once the system is installed, turn on the audio system power and SLOWLY turn up the volume

while playing a favorite music track.

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.

-6-

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.

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

mounted to the panel with the bolt 8 nut, and the tweeter is

then snaooed to the cup.
