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 installa-
tion 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.
Two-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 speaker is normally mounted in factory pre-made
holes in for example Ford and Mazda cars, but can be used in
any other vehicle where they fit.
Filter boxes:
We use separate crossovers (filters) with high class com-
ponents to these speakers in order to get the best possible
sound. Attach the filter boxes are properly to the interior of
the vehicle to avoid rattling. Don’t place them close to the in-
ternal 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 dama-
ge the output circuits of your head unit or amplifier.
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.

We follow a policy of continuous advancement in development.

Warranty service
This speaker is covered by warranty, depending on the condi-
tions 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.
