WARNING! Beforeinstalling check for obstructions behind drywall. To do this make a small hole,
cuttingat a 45° angle (this will make the hole easier to patch if obstructions are found). Only cut out the
mounting hole after you have veried there are no obstructions behind the drywall.
AVERTISSEMENT! Avant l’installation, vérier la présence d’obstacles derrière la cloison sèche.
Poury arriver, percez un petit trou, à un angle de 45° (il sera ainsi plus facile de boucher le trou si des obsta-
cles sont repérés). Percez seulement les trous de montage lorsque vous avez vérié qu’il n’y a pas d’obstacle
derrière la cloison sèche.

Subwoofer Assembly Parts List
• 1 subwoofer
• 1 subwoofer grille
• 1 mounting template.
Your New Subwoofer
Break-In
Allow your MartinLogan subwoofer system to operate for several
hours before you listen critically.
Cleaning
Clean subwoofer housing with a soft, damp cloth. Do not use a
strong or abrasive cleaner or get any part of the subwoofer wet.
If you wish to paint your subwoofer grille, you must do so before
installing it. See the section on ”Color Match Painting” for full details.

The Listening Room
MartinLogan in-wall subwoofers are suitable for use in a wide
variety of listening environments. Note however, that room con-
struction, dimensions and furnishings all play a part in the quality
of sound you ultimately achieve. Try to follow these guidelines:
a. Strong, rigid walls are preferred for best bass balance. For
even better results we recommend adding additional bracing
and acoustic damping material to the cavity prior to installation.
See section on ”Subwoofer Installation” later in this manual for
more details.
b. It is important to note that just as the amount of soft furnishings
has a decided impact on mid and high frequencies, those
frequencies below 150 Hz are dramatically affected by the
room itself—its size, shape, as well as the physical boundaries
of the room.
Guidelines For Deciding On
Subwoofer Placement
When considering subwoofer placement directly into a wall, keep
the following in mind:
• DO NOT install subwoofers in a ceiling.
• DO NOT install subwoofers into lath or plaster — over time, the
bass vibrations will cause material to crack.
• DO NOT install subwoofers into cavities that contain ductwork.
• DO NOT locate subwoofers close to wall mounted fixtures that
may vibrate (remember to check the other side of the wall too!).
• If installing in a wall with metal studs, make sure studs are
securely fastened so that they do not vibrate or rattle.
• Some acoustic bleed-through into the adjacent room is
unavoidable. See section on “In-Wall Cavity Preparation” for
suggestions to reduce bleed-through.
Subwoofer Placement
Subwoofers are recommended to be used in pairs. Using a pair
of subwoofers will allow you to randomize the standing waves
within your listening room so that bass is distributed in a more uni-
form manner. Two subwoofers also ensures even lower distortion,
especially at high output levels.
Bass is less and less directional as it goes down in frequency.
For best sonic integration, placing one subwoofer in the wall at
the front of the room and the other in the wall or at the rear usu-
ally provides the best performance and sonic integration. If this
location is not possible, keeping in mind the guidelines provided
earlier, you may place your subwoofers anywhere in the wall
without affecting the stereo image of your front speakers or the
soundstage of your multichannel speaker system.
Figs. 1a and 1b highlight how bass output is generally affected
by in-wall and placement. When seated in the typical listening
area of your room, placing the subwoofers in the various positions
will typically result in bass performance as follows:
Fig. 1a: Corner placement close to the floor provides the best
balance of output and accuracy.
Fig. 1b: Placement anywhere along the walls close to the floor,
but outside the “shaded” area will provide slightly reduced output,
though still acceptable accuracy.
If desired, for further optimized bass performance and even great-
er output, you can install an additional pair of MartinLogan in-wall
subwoofers. Fig. 1c provides recommended placement for four
subwoofers.
Broken lines in figures represent alternate placement for a pair of
subwoofers.

Color Match Painting
The grille of your MartinLogan In-Wall Subwoofer is finished in
neutral white to blend into any room. However, the grilles may be
painted to match any decor.
Please note:
• Do not paint the surface behind the grille
• Do not use a paint roller or brush
To Paint, Follow These Steps:
1. Remove the grille.
2. Remove the scrim. Set the scrim aside to install after the grille
has dried.
3. In a well-ventilated area, spray a light coat of paint to the grille,
letting the paint dry completely between coats. Always follow
the paint manufacturer’s directions.
TIP! Be careful to not plug the grille holes with paint. Do not paint
the grilles when they are installed on the speaker.
In-Wall Cavity Preparation
When considering subwoofer placement directly into a wall, keep
the following in mind.
Stiffening and Strengthening the Cavity
Although MartinLogan in-wall mounting systems are the most rigid
on the market, when installing your subwoofer directly into a
wall, to help avoid bass vibrations and minimize acoustic bleed-
through, we recommend the following:
Additional Bracing
Additional cross-bracing will further stiffen the cavity. We suggest
placing two to three pieces of 2
” x 4 ” (more if application allows)
within the cavity, evenly spaced above and below the cutout.
Additional bracing can also be sandwiched to the studs/joists on
either side of the subwoofer.
New Construction
New construction offers an excellent opportunity to strengthen and
stiffen the cavity with additional bracing or construction-grade stiff-
ening adhesives applied directly to the drywall. (See Dealer
for more information).
1. Place the mounting template onto the wall. Use a level to make
sure it’s straight (Fig 2a).
2. Trace along the mounting template cut-out (Fig. 2b).
3. Cut a hole as indicated (Fig. 2c).

Wiring Connections
MartinLogan Dynamo in wall subwoofers present a load that is
compatible with 8 ohms. Please refer to your amplifiers owner’s
manual for it’s specific capabilities and wiring instructions.
Subwoofer Installation
IMPORTANT! While it is possible to use a manual screwdriver
for installation, we strongly suggest using a power drill. To avoid
damaging or breaking the clamps, set your drill to a LOW setting.
A high power setting is NOT necessary and may cause clamps to
crack or break from the added force. Such damage is NOT
covered under warranty.
1. Remove the magnetically attached baffle from the subwoofer
assembly (Fig. 4a).
2. Set your Power Drill to the Low setting.
3. Gently position the assembly into the wall cavity (Fig. 4b).
4. Supporting the assembly with one hand, tighten each screw
(Fig. 4c). Stop tightening when you sense resistance.
5. Gently press the baffle onto the front face of the speaker (Fig.
4d). The magnets will ensure correct attachment.
6. Gently press the grille onto the front face of the speaker (Fig.
4e). The magnets will ensure correct attachment.

Warranty and Registration
Your in-wall subwoofer is provided with an automatic Limited 90
Day Warranty coverage. You have the option, at no additional
charge, to receive Limited 3-Year Warranty coverage. To obtain
the Limited 3-Year Warranty coverage you need to register your
product with MartinLogan. For your convenience MartinLogan
offers online warranty registration at www.martinlogan.com.
Please retain your original sales receipt from an authorized
MartinLogan dealer or distributor for proof of warranty terms and
proof of purchase.
MartinLogan may not honor warranty service claims unless we

Service
Should you be using your MartinLogan product in a country other
than the one in which it was originally purchased, we ask that you
note the following:
1. The appointed MartinLogan distributor for any given country is
responsible for warranty servicing only on units distributed by
or through it in that country in accordance with its applicable
warranty.
2. Should a MartinLogan product require servicing in a country
other than the one in which it was originally purchased, the
end user may seek to have repairs performed by the nearest
MartinLogan distributor, subject to that distributor's local servic-
ing policies, but all cost of repairs (parts, labor, transportation)
must be born by the owner of the MartinLogan product.
3. If, after owning your in-wall subwoofer for six months, you relo-
cate to a country other than the one in which you purchased
your subwoofer, your warranty may be transferable. Contact
MartinLogan for details.
