DLS PERFORMANCE SPEAKERS
OWNERS MANUAL
Welcome
Thank you for buying a DLS speaker.
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.
Three-way coaxial system
These speakers have a very good sound but as always it
is important to do a correct installation.
Installation
Speaker drivers:
This kind of speakers are usually mounted in the car’s
parcel shelf. In some older car’s it may also be possible
to install them in the door. We recommend you to install
the drivers in a strong baffle of MDF-board or similar,
this will improve the sound very much. It is important to
fasten the speakers properly in order to avoid bad sound
or rattling.
The speakers are heavy so they must be fastened se-
curely to prevent danger to occupants in a collision
or sudden braking.
Filter boxes:
We use separate crossovers (filters) with high class com-
ponents to these speakers in order to get the best pos-
sible sound. Attach the filter boxes 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.
Install the filter boxes in a dry place. Fasten them with
wire ties. Connect them as in the drawing in this manual.
The filters must be used, if you connect without them
the sound becomes bad and you will destroy the
tweeter.
Wiring:
Use high quality speaker cables. 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 amp-
lifier.
Break-in period
Allow the speakers to play at normal volume for at least
15-20 hours. After this time the performance will be cor-
rect.

Warranty service
This speaker is covered by warranty, depending on the
conditions in the country where it is sold. If the speaker
is returned for service, please include the original dated
receipt (or a copy) with the product.
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.
When the speakers are correctly connected the speaker cone
should move in the same direction 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.
