Introduction
Congratulations on your selection of the Induction Dynamics S2.c 2-way corner-mount
loudspeaker. The S2.c is engineered for smooth performance as a wall-mounted, bookshelf,
or freestanding speaker.
The S2.c 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 S2.c can be combined with any of our main, center, and surround speakers, be they
in-wall, on-wall, or free-standing.
Your S2.c incorporates a 6.5” Kevlar cone woofer with rubber surround and cast frame, and
a 1.125” inverted titanium dome tweeter.
TheS2.cisavailableinRosewoodGloss,BlackSatin,andBlackGlossstandardnishes.
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 connect and operate the
S2.c.
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.
General Care of Your Loudspeaker
Whenever changing speaker wires, interconnect wires, or power cords, always turn off all
equipment.Topreventreorshockhazard,donotexposetheampliertorainorexcessive
moisture.Toavoidelectricshock,donotopentheamplier.Therearenouserserviceable
parts inside.
Yourspeakersandampliercomeinahighqualitynish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.
S2.c Location
S2.c speakers are normally mounted on-wall, but may also be used as bookshelf speakers.
The height of the S2.cs should be determined by locating the tweeter at ear level. The
tweeter reproduces high-frequency audio, which our ears perceive as most directional, so
we are most attuned to their level and placement. Consider whether people will be sitting
or standing in the listening area when placing the S2.cs.
A pair of S2.cs should be placed a few feet from the front wall of the listening area, six
feet or more apart, usually mounted in the corner between two walls, or between a wall
and ceiling. Experiment with the distance between the two speakers to achieve an evenly
spread sound stage. Speakers should be at the same height (with the tweeter at ear level).
Tooptimizebassresponse,varythedistanceofyourS2.cspeakersfromthefrontwall.

Stands
A speaker stand is not included with the S2.c, but is available for purchase through your
authorizedInductionDynamicsdealer.ThecompanionstandfortheS2.cistheST1.S2.c.
Speaker Wire
Use approved wire designed for in-wall or exposed use, as appropriate for your installation.
For the S2.c, 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identies
minimum gauge requirements for various lengths. See your local dealer or installation
contractor for more information.

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
steepcrossoverslope−andthusaatterfrequencyresponse−InductionDynamicsisableto
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specicfrequen-
cies(theS2.cutilizesasinglecrossoverat2500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 sub-
wooferamplier.InductionDynamicsrecommendsasubwoofercrossoverpointbetween
50-60Hz.

6Audio Perfection Realized™
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ndstheoneoptimizationsolutionthat
producesaat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conned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eld
and enjoy clear, undistorted sound regardless
of their position relative to the speakers.

Multi-Channel (Home
Theater) Installation
Speaker Placement and Mounting
Your S2.c speakers surface mount at a 45 degree angle between the ceiling and the wall
or between two walls of your listening room. If possible, prior to installation, connect the
speakers and experiment with their placement within the listening room.
1. The S2.c is shipped preassembled with two mounting bars attached to the speaker. In
ordertoinstalltheS2.cintoacorner,youwillrstneedtoinstallthetwo5/16-18x5/8”
hex head bolts (from the included parts packet) into the mounting bars on the back of the
speaker.Thescrewsshouldonlybescrewedintwoturnsfortherstpartofthisoperation.
2. Square up the corner bracket between the ceiling and wall or two walls so that the slotted
sidesofthebracketlayatagainsttheceilingandwallorbothwalls.Ifyouaremounting
between two walls, make sure that the bolt slots are pointed upward.
3. Use the six #8 x 2” square drive round washer head screws (from the included parts
packet) to screw into the angled holes on the back of the bracket. The holes are angled so
that the screws will hit the corner studs, providing more stability. Therefore, it is important
to screw straight into the holes in the direction they are pointing.
4. If you are running wire into the wall, use one of the oval slots in the side of the bracket
to run wire through.
5. Slide the S2.c, with hex head bolts sticking out from the back, into the bolt slots, making
sure both bolts are in their slot.
6. Tighten the bolts.
7. Attach the cloth grille by carefully pressing the grille mounts into the grille mounting
anges.
S2.c Speaker Connection
Connect the proper output on your home theater processor or receiver to the binding posts
on the S2.c using normal polarity (red to red and black to black).
