REFERENCE SERIES
SUBWOOFERS
WELCOME
Thank you for buying a DLS REFERENCE subwoofer.
The subwoofer must be installed correctly in order to work
well. This manual will show you how to install it like a pro.
Please read the entire manual before beginning the in-
stallation.
Install the subwoofer yourself if you feel confident with
our instructions and if you have the proper tools. However
if you feel unsure, turn over the installation job to someone
better suited to it.
The speakers are designed for use in vented enclosures.
They are NOT suitable for open air, or door mount. Do not
use them as mid bass drivers in the door, they are mainly
designed for subwoofer use.
CONNECTION OF SUBWOOFER
The connection depends on what type of amplifier you
use. The best is to follow the instructions given in the
manual for the amplifier. Most amplifiers today have built-
in lowpass crossover and possibilities to connect your
subwoofer in bridge mode.
If you have a 2 ohm stable amplifier we advice you to
connect the speakers in stereo mode.
If you have a 1 ohm stable amplifier like the DLS Ultimate
amplifiers, it´s possible to connect two 4 ohm subs parallel
in bridge mode.
If you use a DLS mono amplifier like A6, RA10, CAD11,
CAD15 or CA12, you can also connect both speakers in
parallel at a 2 ohm load.
We also recommend the use of a subsonic highpass fil-
ter. This gives a better bass reproduction with less
"rumble". In most DLS amplifiers this feature is already
built-in.
For wiring use high class speaker wires, min AWG13 (2.5
mm
2
). For example
DLS SC 2x2,5.
SUBWOOFER ENCLOSURES, GENERAL
Build your enclosure in a stable and airtight material. The
best is 19 mm MDF-board. Larger enclosures must have
bracing inside to avoid vibrations. The enclosure must be
completely airtight. Use sealing compound in all joints,
also around the cable terminals. The size of the enclosure
is decided by the speaker data.

VENTED ENCLOSURES
In a vented enclosure the sound from the speaker and the
port work together creating a higher sound level. The best
result is achieved if the port is mounted on the front of the
speaker box. Second best is to mount the port on the side
of the enclosure. In the examples for this subwoofer we
advice you to mount the port on the right side of the
enclosure.
The size of the vehicle often decides the practical size of
the enclosure. A smaller enclosure has a higher resonant
frequency than the larger one. The size of the enclosure
should not be so big that the speaker plays below it´s own
free air resonance (Fs), then it looses in power handling
capacity.
We advice you to follow the examples in this manual when
designing an enclosure. These enclosures have been
tested by DLS together with the RW6 drivers.
BANDPASS ENCLOSURES
In all bandpass enclosures the speakers are hidden in-
side the enclosure, all sound is coming out through the
ports. There are different types of bandpass enclosures
and they have in common that they are a bit more difficult
to build.
A suitable example of a band pass enclosure is found on
the back side of this paper.
