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 in­stallation.
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 built­in 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 fil­ter. 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
mm2). 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 in­side 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.

RECOMMENDED SUBWOOFER ENCLOSURES FOR RW6

VENTED ENCLOSURE WITH
TWO RW6

This is the enclosure we recommend you
to build and use for the two drivers in this
kit. It ’s carefully tested and found to be
the best choise. The port to be used is
included with the kit. The tube is cut to it’s
correct length and should not be changed.
There are two ports coming with this kit.
The larger one is for mount on the outside,
and the smaller one should be attached to
the tube inside the enclosure.
Make a round hole in the box where you
want to mount the bass port. Mounting
hole for the port is 115 mm
The larger flange should be mounted in
the box. Fasten it to the box with screws
or with some glue. There are prepared
drill holes on the back of the flange.
The smaller flange is for the inner end of
the tube. Use a PVC-glue to fasten it on
the tube.
Then glue the tube to the port mounted
in the box.
Use sealing compound round the flange
to make the box as airtight as possible.
The given enclosure volume is the inner
volume.

CALCULATE YOUR OWN ENCLOSURE

Box volumes:

When calculating the volume of an enclosure you simply multiply
the width (W) x heigth (H) x depth (D).
Use measures in dm and you will get the answer in liters.

A trapezoid box is calculated like this:

Vol = width (W) x heigth (H) x upper depth (UD) + lower depth (LD)

W

UD

H

LD

Be sure to use the inside
measures to get the correct
volume. The outside measures
depends on the material you use
for the box

h = 25 cm*
w1 = 13,92 cm*
w2 = 23,71 cm* *These are inside measures
d1 = 25 cm*
d2 = 25 cm*
x = 25 cm*

Some useful measure conversions

1 yard (yd) = 3 ft = 36 in = 0,9144 m
1 foot (ft) = 0,3048 m
1 inch (in) = 2,54 cm
1 cubic foot (ft3) = 1728 in3 = 28,32 dm
