DLS Ultimate UP1i Owner's Manual

Welcome
Thank you for buying a DLS Ultimate tweeter.
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. The ULTIMATE speakers are
our best speaker line but 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
The speakers should be installed high up in the door side or
on the dashboard. In competition vehicles they are often
installed in the A-pillar which is a very good installation spot to
achieve a good sound stage. This kind of mounting requires
more job. If you install them in the A-pillar, make sure they are
installed in a strong stable baffle, this will improve the sound
quality.
UP1C comes with mounting accessories for both recessed
and surface mount. Iridium1 and Nobelium 1 are intended for
use only in recessed mounting.
Wiring
Use high quality speaker cables like DLS HQS or similar.
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.
Connect the cables with correct polarity to the speakers.
Break-in period
Allow the speakers to play at normal volume for at least 15-20
hours. After this time the performance is correct.

Crossover
The tweeters must be used with either a passive or an active
filter. When the tweeters are a part of a 2- or 3-way speaker
system, the filters are included, but if you buy them as separate
parts, you must use a separate high pass filter that limits the
lower frequency range. If the tweeters are connected without a
filter they will be destroyed.
A pair of cable filters are normally delivered with the tweeters,
but if you don't have the filters you can build your own filter as
in the drawing below.
If the tweeter level is too high you can connect an extra resistor
in series with the + wire. Use a resistor 3,3 ohms, 5 Watts.
