DLS RM5.2 Installation Manual

Welcome
Thank you for buying a DLS RM-series speaker system.
This model is a part of DLS Reference speaker line.
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. 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.
We recommend you to install the drivers in a strong
baffle of MDF-board or similar, this will improve the
sound verey much. For baffle installation se our advices
on next page. An installation high up on the door side is
to be preferred. If it is possible you should attach DLS
Max damper, asphalt damping mat to the door inside,
this will furher improve the sound.
The tweeter can be installed recessed in the door, on the
dash board or in the 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
interior 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.

Two-way system
This 2-way system have a separate 25 mm tweeter. The
filters are combined low pass and high pass in a plastic
box with selectable tweeter level in four steps inside.
On next pages you can see how to connect the filters and
adjust the tweeter level.
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 in
an active system.
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.
NOTE! The speaker impedance is 3 ohm. If you plan to
connect the RM6.2 in bridge mode the amplifier must
be 1 ohm stable. Not suitable for CA41 and CA51
.
amps
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.
