Introduction
Congratulations on your selection of the Induction Dynamics S2 2-way loudspeaker. The S2
is engineered for smooth performance as a bookshelf or freestanding speaker.
The S2 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 can be combined with any of our main, center, and surround speakers, be they in-
wall, on-wall, or free-standing.
Your S2 incorporates a 6.5” Kevlar cone woofer with rubber surround and cast frame, and a
1.125” inverted titanium dome tweeter.
TheS2isavailableinRosewoodGloss,BlackSatin,andBlackGlossstandardnishes.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.
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.Topreventreorshockhazard,donotexposetheampliertorainorexcessive

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 Location
S2 speakers are normally freestanding, but may also be used as bookshelf speakers. The
height of the S2s 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 S2s.
A pair of S2s should be placed a few feet from the front wall of the listening area, six feet
or more apart. 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
earlevel).Tooptimizebassresponse,varythedistanceofyourS2speakersfromthefront

Stands
A speaker stand is not included with the S2, but is available for purchase through your
authorizedInductionDynamicsdealer.ThecompanionstandfortheS2istheST1.S2.
Speaker Wire
Use approved wire designed for in-wall or exposed use, as appropriate for your installation.
For the S2, 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 identies
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
patentedS4Xinductivelycouplescrossovercoilsandoptimizeseachdriver’sperformance,
individually and interactively with the other drivers. This greatly increases control over
driver range, frequency response, phase and impedance. Because S4X produces such a
steepcrossoverslope−andthusaatterfrequencyresponse−InductionDynamicsisableto
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.
TheS4X’optimizedfrequencyresponsemeansmusicthatmovesdramaticallyupanddown
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.

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“sweetspot”forthelistener.Mostspeakers’driversareonlyoptimizedon-axis,using
measurements from a microphone placed at a single point in front of the speaker. This

Induction Dynamics® eliminates phase differences with respect to height through our Wide

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

this area the sound quality can drastically
decrease, becoming muddy or indistinct.
Patented Wide Angle™ Phase Alignment

of the drivers, noticeably expanding the

Multi-Channel (Home
Theater) Installation
Speaker Placement
5.1 System
A 5.1 system consists of a front left, front right, surround left, suround right, center channel,
and subwoofer channel. An S2 functions equally well as mains or surrounds. In a home
theaterconguration,themainleftandrightchannelsshouldbeplacedafewfeetfromthe
front wall as close to listening height as possible. The surround channels should be placed
to either side of the listening area or behind the listening area at listening height.
6.1 System
A 6.1 system has the same basic channels as a 5.1 system, with the addition of a rear center
channel placed directly behind the listening area.
7.1 System
A 7.1 system has the same basic channels as a 5.1 system, with the addition of a left rear
surround and right rear surround.
S2 Speaker Connection
Connect the proper output on your home theater processor or receiver to the binding posts
on the S2 using normal polarity (red to red and black to black).
