Unpacking Your IWSub Reference
and SubAmp 600
• Please inspect your new equipment carefully. Notify your Definitive
Technology dealer immediately if you notice any damage or missing items.
• Record the serial numbers of your new equipment (usually found on the
rear panels). Note this information in the appropriate place on your Warranty
Card. Mail in your Warranty Card within 10 days of purchase.
• Keep the cartons and packing material. They will do the best job of
protecting your speakers if they need to be transported.
Important Note Concerning In-Wall Installation
The IWSub Reference is designed to be installed inside the walls of your home
quickly and easily. Because of its superb sonic performance, its installation
location within your room is very flexible. But your room is not like anyone
else’s room, and because of its unique size and shape will have its own requirements for optimal sonic performance. We recommend that you consult with the
Custom Installation Specialist at your Definitive Technology dealer regarding
your special needs or if you are at all uncertain about the best and safest way
to install your subwoofer.
• Before starting construction or modification of your walls or ceilings, you
should familiarize yourself with any applicable local fire and building codes.
• Speaker wire must be run inside your wall as part of the installation process
of in-wall loudspeakers. Plan the connection before you start your loudspeaker installation.
• Make sure the locations you select do not conceal studs, electrical wiring or
plumbing. Prior to installation, hold the speaker in your chosen location to
make sure it safely clears obstacles such as studs, corners, beams, lighting
fixtures and door/window frames. Your cutout must be at least 1" (25mm)
from adjoining walls or ceiling, internal studs or plumbing, and a minimum
of 5" above the floor or 1" above the top of the baseboard (whichever is
higher). Note that the frame around the inset loudspeaker extends 1" beyond
your cutout.
• It is highly recommended that you take advantage of the expertise
of a professional installation specialist.
Important Note Concerning Your
IWSub Reference and SubAmp 600
Your IWSub Reference is specifically designed to be used in conjunction with
the Definitive Technology SubAmp 600 and should never be used with another
amplifier. You will not achieve optimal performance, and you may cause damage to your IWSub Reference if you attempt to power it using another amplifier
Mounting Your SubAmp 600 In An Audio Rack
Your SubAmp 600 features side mounting brackets for use in professional audio
racks. When installing the SubAmp 600 in either professional audio racks or
in AV rack furniture, be sure to leave adequate ventilation space around the
SubAmp 600 unit.

Tools Required for IWSub Reference In-Wall
Pencil for marking the location of installation.
Keyhole saw or utility knife for cutting drywall.
Screwdriver, preferably powered, with Phillips head bit.
Power drill with appropriate bit (optional, for starting wall cut).
Template (included: 143/8" x 197/8").
Gasket material (included).
1. The IWSub Reference is designed to be located between two vertical studs,
inside a space of 141/2"–151/2", with the long dimension of the speaker
oriented vertically. If your studs are spaced wider than this, you will have to
shim one side of the inner wall space to properly secure the speaker in a
141/2"–151/2" space.
Figure 1
Figure 2
2. Make certain to incorporate at least 11/4" of space above and below the area
within the inner wall space to make room for the IWSub’s locking arms.
3. With these measurement requirements in mind, place the template against
the inside edge of one of the studs. (Do not “center” the template if your
studs are wider than 141/2"–151/2".) Use a level to make certain the
template is straight and plumb. The outside edge of the template will
be your exact cutout size. [Figure 1]
4. Carefully cut the hole with the appropriate cutting tool for your wall material. Start the hole by drilling a hole on the inside of the template line (with
the drill bit touching the line). Use this hole to insert your saw or knife
and begin cutting. [Figure 2]
Figure 3
Figure 4
5. Before installing the speaker in the hole, apply the four long strips of
gasket material to the speaker: two pieces on each side of the speaker that
will come into contact with the studs. [Figure 3] Use the three shorter strips
of gasket material to pad the rear of the speaker against the back of the
exposed wall. [Figure 4]
Figure 5
Figure 6
6. Once you have cut the hole, fish your previously positioned wiring out
of the hole and connect your speaker. See the next section for detailed
hookup instructions. Make certain that you connect the wire from the
red terminal (+) of your SubAmp 600 to the red terminal (+) on your
speaker and the wire from the black terminal (-) of your SubAmp 600
to the black terminal (-) on your speaker. Be sure to maintain channel
consistency (use either channel one or channel two).
7. Place the subwoofer carefully into the hole [Figure 5]. Secure the sub
enclosure using the 6 screws provided. These screws go into the holes
in the front of the enclosure and angle back into the studs (or, if the space
between your studs was wider than 141/2"–151/2", into the shims). [Figure
6] Tighten all the screws on one side before installing and tightening the
screws on the other side.
8. Secure the locking arms at the top and bottom of the plastic frame
by turning the screws clockwise, taking care not to over tighten.
Making System Connections With Your
SubAmp 600
Recommended Hookup Method One
1. Use a Low (Line) Level RCA connection from your receiver’s LFE Out in
to the LFE Input of the SubAmp 600.
2. Use Speaker Wire to connect the top set of Sub Out Jacks on the SubAmp
600 to the terminals on the IWSub Reference.
3. The SubAmp 600 features an Adjustable Crossover setting on its
front panel. This hookup bypasses the SubAmp 600’s Adjustable
Crossover feature.
Hookup Method One
RCA from Receiver
To Subwoofer
Hookup Method Two
1. Use a Low (Line) Level RCA connection from your receiver’s L and R
Line Level Outputs in to the L and R Input of the SubAmp 600. This
connection is “summed” within the SubAmp 600.
2. Use Speaker Wire to connect the top set of Sub Out Jacks on the SubAmp
600 to the terminals on the IWSub Reference.
3. The SubAmp 600 features an Adjustable Crossover setting on its front
panel. This setting will work with this connection, giving you extra control
over your subwoofer settings.
Hookup Method Two
RCA from Receiver
To Subwoofer
Hookup Method Three—High Level Speakerwire
When using the IWSub Reference for stereo applications, you can feed it either
Low Level signals as described in Hook Up Methods One and Two, or use
Hookup Method Three described here.
1. Connect Speaker Wire from your receiver’s Left and Right outputs to the
Speaker Level Inputs on the SubAmp 600.
2. Use Speaker Wire to connect the Speaker Level Outputs of the SubAmp
600 to your loudspeakers.
3. Use Speaker Wire to connect the top set of Sub Out Jacks on the SubAmp
600 to the terminals on the IWSub Reference.
4. The SubAmp 600 features an Adjustable Crossover setting on its front
panel. This setting will work with this connection, giving you extra control
over your subwoofer settings.
Hookup Method Three

From Receiver
To Subwoofer
Making Adjustments to Your SubAmp 600
The rear panel of your SubAmp 600 features a Remote Mini Plug Input and
Auto/Remote Slider Switch.
• Use this feature to connect your SubAmp 600 to the Remote Out of your
receiver. Moving the Slider Switch to “Remote” will enable your SubAmp
600 to then switch on when you power up your other equipment.
• If a remote connection is not used, this slider MUST be switched to “Auto”
in order for the SubAmp 600 to operate properly.
The front panel of your SubAmp 600 features Volume, Crossover and Phase
Adjustment controls.
Volume Adjustment
Use this setting to control the level (volume) of bass response. Begin with
the volume set at about the 11 o’clock position, and, once you have made all
your other settings, modify this setting for optimum volume and low distortion.
Remember: damage can occur to loudspeakers when an amplifier, regardless of
its wattage, is made to play at higher listening levels than its power can clearly
produce. This is usually beyond the “noon or 1 o’clock” position on the volume
control. If you hear distortion, TURN IT DOWN.
Crossover Adjustment
This control adjusts the frequency range over which your subwoofer operates. In
most situations, the middle range (11 – 2 o’clock) of this control will sound best.
Experiment and let your ears be the final judge. Turning the setting higher will
tend to add more “warmth” to the bass and lower midrange, possibly at the sacrifice of bass “tightness” and midrange clarity. Turning the setting down from the
recommended setting will make the bass and lower midrange sound “leaner.”
Phase Adjustment
Adjusting the Phase can be a little tricky. If you're in doubt, just leave the Phase
at 0 (zero). The best way to adjust the Phase is to get a friend to help you out.
Play music that features a good combination of bass notes and deep male vocals
at different frequencies. Have one person sit in the normal listening position
while the other person slowly rotates the Phase control until it reaches the position that produces the fullest bass sound across the bass spectrum.
Installing More Than One IWSub In Your Room,
Or One Each in Each of Two Rooms
Installing two IWSub References into the walls of your room, or one each in
each of two rooms, will allow you to achieve a mind-blowing amount of bass
from subwoofers that take up no floor space! The SubAmp 600 has two separate
high power amplifiers for just this purpose. It is designed to drive one or two
IWSub References with full performance and maximum power delivered to each
1. Connect inputs to the sub as described in Hookup Methods One, Two
or Three.
2. Use Speaker Wire to connect the top set of Sub Out Jacks on the SubAmp
600 to the terminals on one IWSub Reference.
3. Use Speaker Wire to connect the bottom set of Sub Out Jacks on
the SubAmp 600 to the terminals on the other IWSub Reference.

Painting Your IWSub Reference
The IWSub Reference is easy to paint. It virtually disappears into your room
when it is the same color as your wall. For best results, paint the grille and frame
separately prior to in-wall installation.
You Will Need:
• Paint of your choice (to make the job easier, we recommend spray painting
the grille).
• A paperclip (for removing the paintable grille).
• Masking tape.
• Paint mask (to cover unpaintable parts, supplied).
Preparing to Paint:
1. Separate the parts of the speaker. The grille can be removed simply by
carefully hooking it with a bent paperclip and pulling it gently away from
the frame. [Figure 7]
2. When painting the frame of the speaker, use the supplied paint mask to
carefully mask off the front of the speakers to protect the drivers and baffles
while painting [Figure 8]. You can do this while the speaker is already
installed in the wall (if, for instance, you’re repainting the room). If you do
not have the paint masks, carefully mask the speaker components using
paper and masking tape.
Figure 7
Figure 8
Painting the Frame:
1. Apply paint to exposed (unmasked) parts. Use two or more thin coats.
Spray painting is recommended.
2. When the paint is completely dry, remove the masking material.
Painting the Grille:
1. The grille of the IWSub Reference features an even, protective powder
coating. This powder coating is an ideal primer.
2. Grilles must be spray painted. Do not use a brush and paint. Thick, brushed
paint may clog the grille holes and impair performance.
3. After removing the grille by carefully hooking it with a bent paper
clip and pulling it gently away
from the frame, spray on two thin
coats of finish color. [Figure 9]
If you’re using a compressor and
spray gun, use the finest, most diffuse setting. Be careful not to fill
the holes in the grille with paint.
4. When paint is completely dry,
carefully reinstall the grille.

Troubleshooting Your IWSub
• If, after following these hookup and installation directions, you
experience difficulty, please double-check all wire connections.
• Check the setting of the “Auto/Remote” slider switch on the rear panel of
the SubAmp 600. If no remote connection is made, this switch MUST be
set to “Auto” in order for the SubAmp 600 to operate properly.
• Many amplifiers and receivers have sophisticated internal protection
circuitry. If for some reason your protection circuitry is tripped, turn
down your system’s volume level and wait five minutes before restarting
the system.
