ULTIMATE Nobelium* SERIES
CAR AUDIO SPEAKERS
WELCOME
Thank you for buying a DLS ULTIMATE Nobelium speaker.
This manual will show you how to do a correct installa-
tion. Please read the entire manual before beginning the
installation. Install the speakers yourself if you feel
confident with our instructions and if you have the proper
tools. The ULTIMATE speakers are our best speaker line
but a poor installation job can destroy the final result even
from these speakers. So if you feel unsure, turn over the
installation job to someone better suited to it.
INSTALLATION
Speaker drivers:
Mount the bass speakers in the door sides of your car.
They will fit in the facory pre-made mounting holes but
we strongly recommend the use of a baffle made of
MDF-board or similar to achieve the best performance.
An installation high up on the door side is to be prefered.
An alternative installation is in so called kick panels
down on each side of the floor with the speakers facing
up- and inwards towards the listener. You can also build
a separate sealed box in the door side.
The tweeter can be installed recessed in the dash-board,
or in the door.
It is important to fasten the speakers properly in order to
avoid bad sound or rattling.
Filter boxes:
It´s vital that the filter boxes are attached properly to the
interior of the vehicle to avoid rattling. Don´t place them
close to the internal wiring of the car, this can cause
interference.
Avoid to install filter boxes in the door sides because
they can easily be broken because of rattling or
moisture.
Wiring:
Use high quality speaker cables. Avoid using the factory
pre-installed cabling, they will not give the sound
reproduction that you should expect from the Nobelium
speakers. The DLS SCP cable is a perfect allround
cable for all kind of speakers.
Make sure the cables don´t get jammed causing a short
circuit to ground. This can damage the output circuits of
your head unit or amplifier.
Nobelium 5.2
Nobelium 6.2
Nobelium 8.2
TWO-WAY SYSTEMS Nobelium 5.2, 6.2 & 8.2
These 2-way systems have a separate 1” tweeter. The
filters are combined low pass and high pass in a plastic
box with selectable tweeter level inside.
On the back of this paper you can see how to connect the
filters.
The filters must be used, if you connect without them
the sound becomes bad and you will destroy the
tweeter. You don´t have to use the passive crossover
if the system is connected to separate amplifiers and
an active crossover.
