Introduction
Congratulations on your selection of the Induction Dynamics S1.iw in-wall loudspeaker.
The S1.iw is engineered for smooth performance in any home theater situation.
The S1.iw incorporates exclusive, patented S4X™ crossover and driver-control technology,
which makes possible virtually perfect integration of drivers which are ideal for their intended
frequencies. S4X also provides greatly increased control over frequency response, phase,
and impedance, resulting in superior performance and imaging. Because of S4X technology,
any of Induction Dynamics’ speakers can be used to build a custom home theater system.
Your S1.iw can be combined with any of our main and surround speakers, be they in-wall,
on-wall, or free-standing.
Your S1.iw incorporates a 6.5” Kevlar cone woofer with rubber surround and cast frame, 3”
soft dome midrange, and a 1.125” inverted titanium dome tweeter.
The S1.iw is available in Rosewood Gloss, Black Satin, White Satin, and Black Gloss standard
finishes. Custom paints and stains are also available. Grille fabric is available in 63 room-
complementing colors.

General Information
Please read these instructions thoroughly before attempting to install and operate the
S1.iw.
Check Speaker and Parts
Unpack and carefully check each loudspeaker. If you suspect damage from transit, report the
problem immediately to your dealer and/or delivery service. If possible, save the shipping
cartons for future use.
Each S1.iw comes with a parts packet and mounting hole template. The parts packet contains
a grille mounting flange driver, a selection of grommets with various hole sizes, four stud
screws and a selection of #8 insulated fork terminals. Check to make sure you have all these
items.

General Care of Your Loudspeaker
Whenever changing speaker wires, interconnect wires, or power cords, always turn off all
equipment. To prevent fire or shock hazard, do not expose the amplifier to rain or excessive
moisture.
Your speakers come in a high quality finish that is both attractive and durable. To clean, use
a soft, damp cloth. If your drivers become dusty, dust them with a paintbrush or a brush
vacuum attachment. Do not use a strong or abrasive cleaner.
The grille is covered in acoustic cloth. To keep your grille clear of debris, we recommend
you use a lint roller (like you would use on clothes).
Bass and Loudness Contour Controls
Do not use bass or loudness contour controls. Induction Dynamics’ subwoofers produce
very low frequencies without these controls. Use of these controls will make the bass sound
“boomy”, obscure higher frequencies, and possibly cause damage to your speakers.
S1.iw Location
The S1.iw mounts between wall studs and should be placed in accordance with the speaker’s
application (mains, surrounds, or stereo speakers).
The height of the speaker should be determined by locating the tweeter near ear level. The
tweeter reproduces high-frequency audio, which our ears perceive as most directional, so
we are most attuned to their placement and level. As you make your decision, consider
whether people will be standing or sitting in the listening area. The S1.iw may be mounted
upside down (tweeter nearest floor) to achieve the proper tweeter level with the look of a
higher mounted speaker.

Speaker Information
S4X™ Crossover
The heart of Induction Dynamics® is found in the S4X™ Super Fourth-Order Crossover. The
patented S4X inductively couples crossover coils and optimizes each driver’s performance,
individually and interactively with the other drivers. This greatly increases control over
driver range, frequency response, phase and impedance. Because S4X produces such a
VWHHSFURVVRYHUVORSH DQGWKXVDIODWWHUIUHTXHQF\UHVSRQVH ,QGXFWLRQ'\QDPLFVLVDEOHWR
use the best possible drivers for each range of frequencies, allowing us to sonically match
every speaker in our lineup and to create speaker models able to perform in any combination
and in any acoustic environment.
The S4X’ optimized frequency response means music that moves dramatically up and down
in pitch will never fade in or out, but rather maintain its power as it seamlessly crosses
over from one driver to the next. It also means that frequencies critical to human speech
(frequencies that deliver consonants like “S” and “C”) will sound as natural coming from
your speakers as they would in real life—making dialogue from movies and television sound
crisp and clearly understood.
Above: The S4X crossover routes audio signal to their intended drivers at specific frequen-
cies (700, 3,800 Hz). Because the S4X produces such a steep crossover slope, Induction
Dynamics is able to use the best possible drivers for each frequency range. Subwoofer
crossover points are generally selectable through your subwoofer amplifier. Induction Dy-
namics recommends a subwoofer crossover point between 50-60 Hz.

Wide Angle™ Phase Alignment
In each crossover region, which spans approximately one octave, the sound from two
different drivers must be added together. This simple fact creates problems in most speakers,
because the phase must be matched, not just on axis, but also off axis in order to create a
large “sweet spot” for the listener. Most speakers’ drivers are only optimized on-axis, using
measurements from a microphone placed at a single point in front of the speaker. This
produces a horizontal zone in which the sound is optimized; however there may be drastic
differences in sound quality along the vertical axis—meaning there may be a loss of sound
quality if you stand up, sit, or otherwise move out of the optimized zone.
Induction Dynamics® eliminates phase differences with respect to height through our Wide
Angle™ phase alignment technology. Because our patented circuitry provides additional
variables that can help control phase, Wide Angle finds the one optimization solution that
produces a flat frequency response along the vertical axis, when the microphone (or listener’s
ear) is moved up and down vertically. This means you experience true audio perfection
whether you’re standing, sitting, or lying down.
Conventional Speaker
System
Wide Angle™ Phase
Alignment
Most conventional speaker designs have a
small and horizontally narrow “sweet spot”
caused by inaccurate phase matching of the
drivers. The best quality sound can be heard
only within a very confined area. Outside of
this area the sound quality can drastically
decrease, becoming muddy or indistinct.
Patented Wide Angle™ Phase Alignment
circuitry provides precise phase matching
of the drivers, noticeably expanding the
“sweet spot” both horizontally and vertically.
Listeners are immersed in a large sound field
and enjoy clear, undistorted sound regardless
of their position relative to the speakers.

Installation
Speaker Wire
Use approved wire designed for in-wall or exposed use, as appropriate for your installation.
For the S1.iw, we recommend using high-quality speaker wire that is 12 gauge or lower,
with easily visible polarity coding to make your connections. The following chart identifies
minimum gauge requirements for various lengths. See your local dealer or installation
contractor for more information.

New Construction Installation
In new home construction, or with walls where drywall has not been applied, it is
recommended that you wait until after the drywall application before installing the easy-
mount boxes for the following reasons:
1. The installer gains the control to cut a neat and accurate hole, eliminating possible
mistakes by drywallers.
2. Drywall around the hole is more likely to be flat. This is especially true if any mudding
is done in the vicinity of the hole. The result is a cleaner final fit around the edges.
3. Possible shimming behind drywall can throw off depth calculations and final alignment
of gasket with the face of the drywall. Drywallers sometimes shim to level out the wall
where studs are out of line.
4. Mud and construction dust is kept from getting into the box.
If circumstances require the easy-mount boxes to be installed prior to drywall, then be sure
the gasket on the front of the boxes protrudes out from the edge of the wall studs by an
amount equal to the thickness of the drywall plus 1/4”. Alternatively, the outside back of the
metal box should be 3 7/8” back from the finished drywall surface.
Check for Obstacles Inside Walls
Check the home’s architectural blueprints to verify that your preferred mounting location
is free from obstacles including extra wall studs, electrical wires, plumbing, and heating
ducts.

Locating the Loudspeaker Mounting Holes
1. To find wall studs, use a stud finder. The S1.iw will mount between two studs and should
be positioned so that the tweeter is at ear level.
2. When you’ve decided on a location, cut a 3”
hole in the approximate center of the proposed
cutout area. Measure the exact distances from the
left and right wall studs from the inside of the wall,
to establish the horizontal center line between the
wall studs and mark this with a pencil.
3. Place the mounting hole template flush against
the wall. The template should be centered between
the wall studs, making sure that the left and right
channels are the same height.
4. Using a drywall knife or keyhole saw, carefully
cut along the drawn line and remove the cutout.
5. Before installing the easy-mount box into the
walls, you will need to bring the speaker wire into
the mounting hole. Be sure to leave plenty of extra
wire coming into the mounting hole, especially if
you are bringing in the wire from below since the
speaker wire access holes are at the top of the easy
mount box.
Installing the Easy-Mount Box Into the Wall
1. The S1.iw is shipped preassembled with the faceplate attached to the easy-mount box
with bolts. In order to install the S1.iw easy-mount box into the wall, you will first need
to separate the faceplate from the box. First, remove the grille mounting flanges, using
the grille mounting flange driver. Note that there may be shims under some of the grille
mounting flanges. You will need to save these shims to use when you reinstall the faceplate.
Then unscrew the faceplate mounting bolts using a 1/4” hex key or driver. You will later
reattach the faceplate with these same faceplate mounting bolts. See illustration on page 11
for an exploded view.

2. There are two speaker wire access holes located at the top of the easy-mount box. The
box comes with a solid grommet preinstalled in the large hole and a small size grommet
preinstalled in the smaller hole. The grommet hole size you will need depends on the size
of the wire you are putting through the hole. In the parts pouch you will find a selection
of large and small grommets that have holes through them of various sizes. Use a grom-
met of the appropriate size to get a snug fit around the speaker wire where it enters the
box. Put a solid grommet in the other hole. Make sure there is enough extra speaker wire
feeding into the box for easy handling of the loudspeaker faceplate.
3. Place the easy-mount box into the mounting hole.
4. Snug the Stud Grabber™ bolts against the left and right wall studs just enough to cause
the easy-mount box to be suspended in the cutout opening. Do not overtighten these
bolts to avoid distorting the studs or box. Make all necessary adjustments to level and po-
sition the easy-mount box in the wall. The preferred method is a small level held against
the inner side of the easy-mount box to make sure it is perfectly vertical. Upon comple-
tion, the box should be level and centered in the cutout opening with the box gasket pro-
truding 1/4” out from the drywall surface.
5. Tighten the Stud Grabber lock nuts with a wrench.
6. Place the 4” stud screws into the hole in the inside of the Stud Grabber bolts. Carefully
pound them in about 1/4” with a hammer to get the threads started. Tighten each of the
screws with a #2 square head screwdriver until the screws are snug.
This assemble consists of an outer flange, inner flange, lock nut, bolt and 4" stud screw.

Installing the Faceplate
While installing the faceplate, we recommend that an assistant help hold the faceplate. Be
careful working with the assembly that you don’t damage any of the speaker components.
If the 3” soft dome midrange gets dented in, you can work it back out with your fingertips or
use a vacuum cleaner to suck it out.
1. Hold the speaker faceplate up to the wall opening and attach the speaker wire to the
terminal block on the back of the faceplate, observing the proper polarity. To make the
connections to the terminal block, solder or crimp with high pressure the insulated fork
terminals provided in your parts packet. Soldering is best. For in-wall use make sure the
compensator switch is in the proper position.
2. Position the speaker faceplate over the easy-mount box. Gently move it around from
side to side and up and down until the rubber gasket slides around the faceplate mounting
inserts. Screw in the faceplate mounting bolts, gently tightening each one a little at a time,
until the faceplate is approximately 1/32” from the drywall all around. DO NOT TIGHTEN
THE BOLTS ANY FURTHER. The faceplate should not contact the drywall. This avoids any
vibration or distortion of the drywall.
3. Install the grille mounting flanges that came in the parts packet using the grille mounting
flange driver. Any shims that were removed should be replaced back under the grille
mounting flanges to make them level with the faceplate. The grille mounting flanges should
be used even if the grilles are not, as this gives the loudspeakers a finished appearance.
4. Attach the cloth grille by carefully pressing it into the grille mounting flanges.
Connecting to an Amplifier
1. Be sure the amplifier is turned off to avoid damage to the speakers.
2. Connect the speaker wires to the speaker outputs on your amplifier. Observe proper
polartity (red to red and black to black).
3. Make sure each speaker is connected to the correct amplifier output (e.g. left front
loudspeaker to left front output).
