Introduction

Congratulations on your selection of the Induction Dynamics® S1.8Swd 3-way/dARTS, on-

wall, surround loudspeaker. The S1.8Swd is engineered for smooth performance and very

high power handling.

Induction Dynamics dARTS uses complex circuitry and room correction software to carefully

match each speaker to a room’s unique acoustic signature. This provides uniform, precise

sound reproduction throughout the entire listening area, making every seat in the room a

“sweet spot”.

The S1.8Swd 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 S1.8Swd can be combined with any of our center and surround

speakers, be they in-wall, on-wall, or free-standing. For more details on S4X technology, see

the “speaker information” section of this manual.

Your S1.8Swd incorporates an 8” Kevlar cone woofer with a coated foam surround and cast

frame, dual 3” soft dome midranges and dual 1.125” high-power soft dome tweeters.

WARNINGS:

WARNING! - SHOCK HAZARD

General Information

Please read these instructions thoroughly before attempting to connect and operate the S1.8Swd.

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

carton(s) for future use.

General Care of Your Loudspeaker

Whenever changing speaker wires, interconnect wires or power cords, always turn off all

equipment. There are no user serviceable parts inside.

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.

S1.8Swd Location

The S1.8Swd mounts on drywall, preferably over studs, and should be placed in accordance

with the type of system you are installing as discussed on page 7. The S1.8Swd was designed

in such a way that the tweeter will be at ear level when the audience is sitting. The tweeter

reproduces high-frequency audio, which our ears perceive as most directional, so we are

most attuned to their level and placement.

A pair of S1.8Swd speakers should be placed 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).

A certified installer will finalize the placement of your S1.8Swd speakers in accordance with

the Audyssey MultEQ XT software. For more information, refer to the SX7000d instruction

manual.

Speaker Wire

Use approved wire designed for in-wall or exposed use, as appropriate for your installation.

For the S1.8Swd, we recommend using high-quality speaker wire that is 14 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.

WIRE LENGTHS / MINIMUM GAUGE REQUIREMENTS

Length (in feet) AWG size and stranding

up to 18’ 14 gauge (19/27)

up to 29’ 12 gauge (65/30)

up to 61’ 10 gauge (105/30)

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 flatter frequency response, Induction Dynamics is able

to use the best possible drivers for each range of frequencies. This allows 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 Hz, 3800 Hz). Subwoofer crossover points are generally selectable through your

subwoofer amplifier. Induction Dynamics recommends a subwoofer crossover point be-

tween 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 reduces phase differences both horizontally and vertically through

our Wide Angle® Phase Alignment technology. Because our patented circuitry provides

additional variables that can help control phase, Wide Angle finds the one optimized

solution that produces a flat frequency response along both the horiztonal and vertical axis.

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.

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 S1.8Swd functions as a rear surround speaker. In a home

theater configuration, 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.

A certified installer will finalize the placement of your dARTS speakers in accordance with

the Audyssey MultEQ XT software. For more information, refer to the SX7000d instruction

manual.

Installing the Easy-Mount Box Onto the Wall

1. The S1.8Swd is shipped pre-assembled with the faceplate attached to the easy-mount

box with bolts. In order to install the S1.8Swd onto the wall, you will first need to separate

the faceplate from the box. First, remove the grille mounting flanges, using the grille mount-

ing flange driver. Note that there may be shims under some of the grille mounting flanges.

You will need to save these shims for use when you reinstall the faceplate. Once the grille

mounting flanges and shims are removed, use a 5/16” hex key or driver to unscrew the face-

plate mounting bolts. You will later reattach the faceplate using these same bolts.

2. There are speaker wire access holes located on the back plate of the easy-mount box,

the box comes with a solid grommet pre-installed in each of the nine holes. Any solid

grommet may be replaced with a regular grommet. The grommet hole size you will need

depends on the size of the wire or screw you are putting through the hole. You will need to

feed one set of speaker wire into the S1.8Swd.

In the parts packet you will find a selection of regular grommets with holes through them

in varying sizes. Use of a snug fitting grommet is important to get a good seal around the

speaker wire or screws where they enter the box. Once you have determined the proper

grommet sizes, feed the speaker wire through its grommet. Make sure there is enough extra

speaker wire feeding into the box for easy handling of the loudspeaker faceplate.

3. If possible, find a wall stud to screw the easy-mount box into. To find a wall stud, use a

stud finder.

4. Square up the easy-mount box over the stud at listening height using a level.

5. If you can screw into a wall stud, use 2 #10 x 2” square drive round washer head screws

with metal washers (from the included parts packet). These screws should fit snugly in the

appropriate size grommet hole. Make sure that any holes not used for mounting or running

speaker wire have solid grommets in them. These solid grommets not only seal the box, but

also act as a rubber cushion between the box and the wall.

6. If you cannot screw into a wall stud, use 4 dry wall anchor bolts that spread out behind

the drywall. Select grommets that fit snugly around the bolts you have chosen. Be sure to

put a metal washer between the head of the bolt and the grommet.
