DLS R4, R5, R6 REFERENCE series
Thank you for buying DLS REFERENCE 2-way system.
This instruction will help you to do a correct installation.
If you want to get the best sound from your speakers we advice
you to read and follow this instruction.
If possible mount the speakers in a baffle of MDF-board or similar
to avoid rattling.
For best result use high quality speaker cables, minimum 1,5 mm
For example the DLS SC 2 x 1,5.

MOUNTING:

Mount the speakers in the door or in the dashboard of your car.
Normally they will fit in the cars original mounting hole. If
possible reinforce with a baffle of MDF-board or similar. An in-
stallation 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. An installation of the tweeter close to the
bass/mid element is to be prefered. The tweeter can be installed
on the dash-board, or recessed in the door with the accessories
in the kit.
It is important to fasten the speakers properly in order to avoid
bad sound and rattling.
The filters included with the speakers must also be fastened
properly to avoid rattling. Don´t place them close to the internal
wiring of the car, this can cause interference. Make sure the
cables don´t get jammed causing a short circuit to ground. This
can damage the amplifier circuits.
The speaker grilles are mounted in the plastic speaker frame by
the use of the rubber coumpound included in the packing.
Spread the compound even in the frame.
The sealing strip coming with the kit can be used for improved
sealing between the bass element and the mounting surface.
The tweeter installation is described in the instruction sheet
coming with the tweeters.

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.

BUILDING BOXES

If you want to build a box to your
speaker a sealed type is to be
prefered. The box volume can vary
depending on how much bass you
want from your speakers. For
fullrange use of the speakers,
follow the recommended box
volumes in the table. If you want to
limit the reproduction at for ex. 100
Hz, divide these volumes by half.
