Setting the level too hig h w ill cause the bass to seem bloated and is the sing le most common cause of bad sounding
subw oofers. A rule of thumb is that the subwoofer should
not draw attention to itself, but should simply make the systems low end seem more extended and accurate.
Phase Control Switch
The phase con trol is entirely dependent on the size a nd
configuration of your listening enviro nment, the placement
of the unit, and your seating arrangement. Due to the w ay

As a general rule the low pass filter should be set equal
to approximately 7 0 % of your speaker's lowest frequency
response . Remember, this is a general rule. We advise
that once you try the recommended setting using the formula above, you should try the surroundi ng settings to see
w hich sounds best.

This setup is recommended if your subwoofer will be used
in a dedicated home theater or multi-channel system. When
a signal is connected to the subwoofer's LFE input, and the
crossover switch is set to 'Bypass (LFE In)' the internal low pass
filter is not active. By following this setup, you will allow your
processor to handle most of the bass management.
If you w ill be using your system for both 2-channel and
multi-channel listening we recommend using this setup

AC Power Connection
power cord should not be
installed, removed, or leh detached from
the subwoofer while the other end is connected to an AC power source.
The IEC power cord should be firm ly inserted into the AC
power receptacle on the rear connection panel of the
subwoofer, then to any convenient AC wall outlet. The sub
also integrates a signal sensing pow er supply that automatically switches off after sensing no music signal for several
minutes (this will occur when the power switch is set to 'Auto').
Your subwoofer is wired for the pow er service supplied in
the country of original consumer sale. The AC pow er rating applicable to a particular unit is specified both on the
pocking carton and on the serial number plate attached to
the subwoofer.
If you remove your subwoofer from the country of o rig inal
sole, be certain that AC power supplied in any subsequent
location is suitable before connecting and operating the
subwoofer. Substa ntially impaired performance or severe
damage may occur to the subwoofer if operation is attempted from an incorrect AC pow er source .
Replacing the Fuse
2 Press the sync button on the SWT-2 transmitter and hold for
3 seconds. The LED will blink quickly . If pairing has completed successfully both LEDs will stop blinking and remain
on. Please note: If a link is not established aher 30 seco nds this transmitter's LED w ill start blinking slowly. Repeat
both steps. Please note: The LED will blink slowly if the
w ireless transmitter is not in use. This blinking is part of the
normal operation of the w ireless subwoofer system. If you
should choose to mask this LED with a small piece of tope
or other opaque material doing so will not affect the performance of the subwoofer.
WARNING! For best performance w e recommend that
the SWT-2 wireless transmitter not be placed on the floor.
WARNING! When operating w irelessly this subwoofer
may be suscepti ble to RF interference in the 2 .4G Hz
ba ndwidth fro m microwave ovens a nd w ireless devices
such as WiFi systems, video game consoles, cordless
telephones , blue tooth devices, and baby monitors.
G enerally, this issue (intermittent sound or slight popping
no ises) is easily resolved by physica lly separating problematic devices from one another-a distance as little as
two feet will ohen alleviate the interference. In the case of
microwave ovens, the interference w ill only occur when
the microwave is operating.
If the fuse in your subwoofer sho uld require chang ing , turn
off a nd unplug your subwoofer befo re removing the fuse.
Replace w ith a matching fuse .
O ur custom made woofers require approximately 50 hours
of break-in at moderate listening levels before their opti mal
performa nce occurs. This will fa cto r in on any critical listening and judgment.
Optional Wireless Connection
The Dynamo l OOOW and 7 00W subwoofers incorporate
a wireless receiver for use with the M artinLoga n SWT-2

Listening Position
Generally, subwoofers have the most output when placed
in the corner of a room. However, this can also exaggerate the subwoofers output making blending difficult. We
recommend starting by placing the subwoofer in a corner. If, after the full range of tuning techniques have been
employed, the subwoofer sounds like it has too much upper
bass energy try pulling it away from the wall, toward the
listening position. Th is will lessen the reinforcement of these
problematic frequencies from the wall and likely smooth out
the response. Repeat the tuning techniques with the woofer
controls after you move it (see figure 7).
Ask Your Dealer
Your Martinlogan dealer can suggest many options for
optima l subwoofer placement. They also have many tools
at their disposa l, such as experience, familiarity with the
associated equipment, and even sound analysis equipment
w hich may make the task of determining optimal subwoofer
placement easier.

Installing in a Cabinet
When placing the subwoofer inside of a cabinet it is recommended that there be o minimum of three inches of open
space between the cabinet and the front and bock sides
(see figure 8 ).

Figure 9. The Dynamo l OOOW and Dynamo 700W are capable of both front-firing and down-firing woofer orientations.
Changing Woofer Orientation
When installing the subwoofer in a cabinet it is recommended that the subwoofer be converted to a front firing
configuration. (see figure 9).
Prepare a flat surface with a blanket to protect the finish.

Your Room
This is an area that requires both a little background to
understand and some time and experimentation to a ttain
the best performance from your system. Your room is actually a component and an important part of your system.
This component is a Iorge variable and can dramatically
add to or subtract from a great sonic experience.
All sound is composed of waves. Each frequency has its
own wove size, with the lower, or boss frequencies literally encompassing from l 0 feet to as much as 40 feet. Your
roo m pa rtic ipates in this wave experience like a sw imming pool with waves reflecting and becoming enhanced
depending on the size and shape of the room and the
types of surfaces in the room.
Remember that your audio system can actually generate all
of the information required to recreate a sonic event in time,
space, and tonal balance. Acoustically, the role of on ideal
room w ould be to neither delete nor contribute to that information. However, nearly every room does to some degree.
Standing Waves
Sound coming from a speaker bounces around in a room
until a pattern emerges-this is called a standing w ove.
Typically, this is o nly a pro blem w ith frequen c ies below
l OOHz. When this ha ppens different parts of yo ur room
experience either an excess or a lack of boss.
Some peo ple believe that having a room without para llel
walls will eliminate this effect. The truth is that non-parallel
walls only generate different standing wove patterns tha n
those that occur in recta ng ular rooms.
with the music, and may contribute in a nega tive way to
the sound. Ringing , boom iness, and even brightness can
occur simply because surfaces and objects are "singing
along" w ith your speakers.
Resonant Cavities
Small alcoves or closet type areas in your room can be
chambers that creole their own "standing w aves" and can
drum their own "one note" sounds.
Solid Footing
After liv ing and exper imenting with yo ur subwoofer,
you may want to use ETC™ (Energy Tran sfer Coupler)
Spikes (see figure l l ). W ith the use o f these spikes,
the subwoofer will become more firm ly planted o n the
floor a nd , co nsequently , bass will tighten. It is best not
to implement the spikes, however, until you are secure in
the positioning, as the spikes con damage the floor if the
subwoofer is moved.
Spike Installation Instructions:
Carefully lay the subwoofer on its side to gain access
to the bottom of the feet.
2 Firmly press the spikes into the feet.
Caution: Make sure yo ur hand s a nd any c a bling are
clear of the spikes . Do not slide the subw oofer as spikes
are sharp and can damage your floor or carpet.
Usually, you can exc ite most o f the standin g waves in
a roo m by putting the subwoofer in a corn er. Li ste ning
pos ition determines w hich standing w aves yo u will experien ce. For instance, if yo u sit in a corner you will hear
most of the stand ing waves . This can be on overpow ering
experien ce . Sitting next to a wall con also intensify the
levels of the sta nding w aves tha t are experienced.
Resonant Surfaces and Obiects
A ll of the surfaces a nd objects in your room ore subject to
the frequencies generated by your system. Much like a n
instrument, they w ill vibrate and "carry on" in syncopation
Figure 11. To insta ll the spikes, press them into the feet.
Room Acoustics
It had long been the practice of stereo buffs to connect their
television to a stereo system. The advantage was the use
of the larger speakers and more powerful amplifier of the
stereo system. Even though the sound was greatly improved, it
was still mono and limited by the broadcast signal.
In the late 1970's and early 1980's two new home
movie formats became widely available to the public:
VCR and laser disc.
By 1985, both formats had developed into very high quality
audio/video sources. In fact, the sonic performance of some
video formats exceeded audio-only formats. Now, with
theater-quality sound available at home, the only element
missing was the "surround sound" presentation found in
movie houses.
Fortunately, Dolby and DTS encoded DVD's emerged
with the same surround sound information encoded on
home releases as the theatrical release. Additionally,
new high-resolution home-viewing formats such as Blu-ray
as well as high-definition content provided via cable or
satellite have evolved which include multi-channel encoded audio that is virtually master tape quality. All that is
required to retrieve this information is a decoder and additional speakers and amps to reproduce it.
speaker, and that it is recommended for use as a center
speaker. This is not the place to cut corners.
Surround Speakers
We recommend (along with the film industry) that the surround speakers play down to at least 80 Hz. Surround
speakers contain the information that makes it appear that
planes are flying over your head. Some may suggest that
this is the place to save money and purchase small, inexpensive speakers. If you choose to do so, be prepared
to upgrade in the future as discrete multi-channel digital
encoding is proliferating rapidly and the demands on surround speakers have increased.
With any good surround system you will need one or
more high-quality subwoofers (the .1 in a 5.1, 6.1, or 7.1
channel surround system). Most movie soundtracks contain
large amounts of bass information as part of the special
effects. Good subwoofers will provide a foundation for the
rest of the system.
Home theater is a complex purchase and we recommend
that you consult your local Martinlogan dealer, as they
are well versed in this subject.
Each piece of a surround system can be purchased separately. Take your time and buy quality. No one has ever
complained that the movie was too real. The following list
and descriptions will give you only a brief outline of the
responsibilities and demands placed on each speaker.
Front Left and Front Right
If these speakers will be the same two used for your stereo
playback, they should be of very high quality and able to play
loudly (over 102 dB) and reproduce bass below 80Hz.
Center Channel
This is the most important speaker in a home theater
system, as almost all of the dialogue and a large portion of the front speaker information is reproduced by the
center channel. It is important that the center speaker
be extremely accurate and mate well with the front
