INTRODUCTION
Congratulations on your purchase of the world’s finest brand of car audio speakers.
We have invested tremendous effort in the design process of the new Velocity speaker series, in order to achieve superior musical performance. For maximum performance and reliability we highly recommend that your new
Velocity speakers be installed by an authorized Velocity dealer.
For additional information on the Velocity Product Line visit our internet site at: http://www.velocity.de.
KEY COMPONENT FEATURES
The
Velocity
on performance and ease of installation. Key feature include:
• High power handling and low distortion for the woofer due to the Extended Pole design.
• High power handling for the ”Polyfoam“ tweeter through the use of Neodymium magnets and a circuit breaker type ”poly-switch“ that open the circuit to the tweeter, if overdriven
• Reinforced Polypropylen woofer cones to maintain rigidity and resistance to moisture
• Butyl rubber soround for great cone excursions at low frequencies
• Clear, clean high frequency response and transparency with ”Polyfoam“ dome tweeter
• Easy installation of woofers with car specific design
• 12/12 dB/octave linear phase crossovers with high frequency adjust of level and crossover frequency
• High efficiency
• Speaker and crossover terminals with screw connectors
• The extended pole design offers a longer symmetrical magnetic field compared to a conventional flush type
pole.
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.
ProComponent sets offer tremendous performance because of well thought out designs focusing

Safty Considerations
Before starting to mount your speaker, read the mounting and connection instructions carefully. Discon
nect the vehicle battery's negative terminal before making connections.Be sure to observe the safcty
notes of the aotomobile manufacturer (airbags, alarm sx stems, onboard computers, immobilisers). Befo
re drilling holes, look to see what is on the other side- making holes into the battery, wiring looms or fuse
box is not recommended.
SOUND QUALITY VS. LOUDNESS
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 cymbals, through human voices and most
instruments, and down to the very low tones from synthesisers and drums. Frequency response includes timbre
(the accurate replication of an instrument), linearity (the tonal quality is the same regardless of volume level),
and clarity (lack of distortion of the original signal). Velocity 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 Velocity speakers excel here due to angled tweeter mounting and smooth off-axis frequency response ensuring accurate reproduction.
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 a Velocity subwoofer can offer stunning performance!
The increase in amplifier power help 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.

MECHANICAL AND ELECTRICAL INSTALLATION
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 woofers 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.
Speaker wiring must be isolated from the electrical system of the car and routed away from any factory systems
to avoid potential noise pickup. Use braided wire with 2.5 to 4 mm cable cross section.
FINAL WOOFER INSTALLATION
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 Velocity unit.
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.

FINAL TWEETER INSTALLATION
The biggest advantage of Velocity component speakers is their ability, when properly installed, to provide a
tonally accurate sound with a wide sound stage but pinpoint localisation of performers. The largest impact over
this sound stage is provided by the tweeter location. To determine this optimal location 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 Velocity 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.
4. Enjoy the music, with good tonal balance and good staging in your car.
