WELCOME

Thank you for buying a DLS ULTIMATE Nobelium speaker.
This manual will show you how to do a correct installa­tion. 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.

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.

SPEAKER ENCLOSURES

If you want to install the speaker in an enclosure the
recommended sizes are:

Nobelium 5,25” bass driver in a kick panel:
min 3 liters (0,105 cuft) and max 5 liters (0,18 cuft).

Nobelium 5,25” bass driver in door side: 5 liters (0,18
cuft) sealed box.

Nobelium 6,5” bass driver in a kick panel:
min 4 liters (0,14 cuft) and max 6 liters (0,21 cuft).

Nobelium 6,5” bass driver in door side: 6 liters (0,21 cuft)
sealed box.

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.

SPEAKER PHASING

To be sure to have the correct speaker polarity (phase) you can
check this by using a 1,5 Volt battery.
Connect a cable from the battery plus-pole to the speaker plus,
and a cable from the battery minus to the speaker minus.
If the speakers are correctly connected the speaker cone should
move outwards on both right and left channel.
This check must be made on the cables going from the speakers,
to the output terminals of your car stereo or amplifier.

TWEETER INSTALLATION
Nobelium1

Nobelium1 can be installed recessed in a doorside.

RECESSED MOUNTING 1:

You need a hole with a diameter of 46 mm / 1,77" in the door side.
Attach the tweeter driver to the door side (or where you prefer to
install it) and use the four long screws to attach it.

RECESSED MOUNTING 2:

Sometimes it´s necessary to install the tweeter at places where you
cant use the round flange. The flange (A) is possible to remove from the
tweeter element (B) by turning it CCW.
If you prefer to install the tweeter with the flange attached to the tweeter
element, we recommend you to add a string of strong glue on the bot­tom side, between flange and chamber, to secure it. This gives you the
best sound reproduction in this installation.
