FILTER DIAGRAM:
DLS U35 & U36, ULTIMATE series
NOTE, IMPORTANT!
The bass element in the drawing above is connected phase reversed.
Connect it as the marking on the filter box. If the system is used
together with a subwoofer try to phase reverse this also.
If you run the system without the bass element connected to the
filter you must disconnect the 33
µµµµµ
F capacitor inside the filter box
(cut off one lead).
Tchnical data on the back side.
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 in the same direction on both right and left
channel (normally outwards). This is not working on mid and
tweeter elements.
This control must be made on the cables that goes to the
speaker terminals of your car stereo or amplifier. If you have
an extra highpass filter in line with the bass element you can´t
see any cone movement, you must first disconnect the filter.
If you have any questions about this product, contact
your local dealer or DLS customer support center.
Thank you for buying DLS ULTIMATE 3-way system. This
instruction will help you to do a correct installation. This kit is de-
signed to reproduce the music in a natural way and it is the best
there is on the market. In order to get the best sound possible
from your speakers we advice you to read and follow this
instruction. A poor installation can ruin the sound from even the
most expensive speaker system.
MOUNTING:
Bass element 5,25" / 6,5"
Mount the speakers in the door side. If possible reinforce with a
baffle of MDF-board or similar. A mounting high up on the door
side is to be prefered. An alternative mounting is in kick panels
down on the floor on each side with the speakers facing up- and
inwards towards the listener. The best result will be achieved
using sealed boxes for the elements, 5-6 liters maximum. It is also
possible to use a membrane box of 2-3 liters. A mounting in the
door side without the use of boxes will lower the power handling
capacity, the cone movement will be too large causing a bad bass
reproduction. In a system with a separate subwoofer, and active
crossover, the system should be used with a 120-150 Hz high-
pass x-over. When using a passive x-over to the subwoofer,
connect a 150 - 200
µ
F capacitor in series with the 5,25" / 6,5"
bass element.
It is important to fasten the speakers properly in order to avoid
bad sound and rattling.
2,5" midrange element U2,5:
Should be mounted high up in the door side or in the dashboard.
Normally these speakers don´t require any box. To get an
improved midrange, mount the U2,5 chamber box behind the
dome (extra accessory). When the midrange is mounted high up
in the dashboard the mid level becomes high. If so use the low mid
level in the filter box (jumper J1). If the level is still too high,
connect a 3-5 ohm resistor in series with the s feed.
1" tweeter RC1:
A tweeter mounting together with the bass/mid element is to be
prefered. The tweeter can also be mounted on the dash-board or
recessed in the door using the delivered tweeter accessories. If
the midrange elements are mounted in the dashboard the best
sound stage will be achieved by mounting the tweeters in the front
side posts directed towards each other. The tweeter level can be
adjusted inside the filter box with jumper J2.
Filter boxes and grilles:
The filters included with the speakers must also be fastened
properly to avoid rattling. Don´t place them close to the cars cable
mats, this can cause interfering sounds. Make sure the cables
don´t get jammed causing a short circuit to ground. This can
damage the amplifier circuits. Both tweeter and midrange levels
can be adjusted in two steps inside the filter box by moving the
two jumpers J1 and J2. Make your own tests for best result. To
remove the cover just press on both sides and lift it upwards.
NOTE! The filters must be used. If the tweeters are connected
without filters they may be damaged and the sound reproduction
will be bad.
The speaker grilles are mounted in the plastic speaker frame by
the use of the rubber coumpound coming with the system. Spread
the compound even in the frame.

CONNECTION:
The drawing shows the connection of a 3-way system to one
channel. The other channel is connected in the same way. The
tweeter and mid levels are adjustable in two steps as described
below:
Tweeter level:
High = jumper connected between pin 2-4.
Low = jumper connected between pin 1-2.
Midrange level:
High = jumper connected between pin 1-2.
Low = jumper connected between pin 2-4.
