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.

TheS2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.

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 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

earlevel).Tooptimizebassresponse,varythedistanceofyourS2speakersfromthefront

wall.

Stands

A speaker stand is not included with the S2, but is available for purchase through your

authorizedInductionDynamicsdealer.ThecompanionstandfortheS2istheST1.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 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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 fre-

quency range. Subwoofer crossover points are generally selectable through your subwoofer

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

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

theaterconguration,themainleftandrightchannelsshouldbeplacedafewfeetfromthe

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).
