DLS RC6.3 Owner's Manual

DLS REFERENCE SPEAKERS
Welcome
Thank you for buying a DLS RC6.3 speaker system. This
model is a part of DLS Reference line.
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.
A poor installation job can destroy the final result even from these
fine 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. We
strongly recommend you to install the drivers in a strong baffle
of MDF-board or similar. For baffle installation se our advice on
next page. An installation high up on the door side is to be pre-
ferred. The 2,5" midrange driver should also be installed high
up on the A-pillar or in the door.
The tweeter can be installed recessed in the door or A-pillar. It
is important to fasten the speakers properly in order to avoid
bad sound or rattling, a separate baffle will improve the sound
also for the tweeter.
Filter boxes:
It's vital that the filter boxes are attached properly to the inte-
rior of the vehicle to avoid rattling. Don't place them close to
the internal wiring of the car, this can cause interference.
Avoid installing the 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 these high class 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.

Three-way system RC 6.3
The 3-way system have a separate 25 mm tweeter, RC25, and
a 2,5" midrange, UPi2,5, playing together with a 6,5" woofer.
Crossover boxes
RC6.3 has a two crossover boxes, one for each channel. On
next page 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 using active crossover.
Break-in period
Allow the speakers to play at normal volume for at least 15-20
hours. After this time the performance will be correct.
Connection of speakers
Make sure you connect the cables with correct polarity to the
speakers. Observe the markings on the terminals. The red
marked terminal is plus and the black is minus.
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 spea-
kers, to the output terminals of your car stereo or amplifier.
