FREESTANDING SPEAKERS
Please read the following instructions carefully before installing your Induction Dynamics
®
freestanding speakers. If you have
any questions regarding installation that are not answered in the following directions, please contact your local sound contractor
or the Induction Dynamics

technical support team. Contact information can be found on the back of the manual.
General Information
Your speakers and amplifier 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).
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
due to excessive cone excursion.
Amplifer location: The A2 amplifier is best located in an equipment rack or shelving with other audio and video equipment. It is
not recommended for placement behind walls or other limited access locations, where service may be restricted.
Carpet spikes are not required for these speakers. However, they have been provided if you would prefer to use them. Should
you choose to do so, lay the speaker on its back side, then screw the carpet spikes into the threaded holes under the base of
each speaker.
Speaker Wiring: Use approved wire designed for in-wall or exposed use, as appropriate for your installation. For freestanding
speakers, 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.
Two-Channel / Stereo Installation
For two-channel stereo listening it is recommended that you place your speakers a few feet from the front wall of the listening
area. Generally, two-channel loudspeakers are set between six and twelve feet apart in small to medium listening rooms. Vary
this distance until you achieve an evenly distributed soundstage with the center filled in. To optimize bass response, vary the
distance of the speakers from walls and corners, paying special attention to any low frequency nulls in the listening area.
Induction Dynamics drivers are carefully selected and optimized for uniform polar response. This means that the tonal quality
of the speakers remains the same off-axis, so it is not necessary to “toe in” the speakers. However, due to variations in the
patterns of reflections from one room to another, you may notice a slight improvement in the soundstage at the center listening
position if the speakers are “toed in”. Start with approximately 20 degrees each, and experiment with different angles. The best
angle will vary with different listening rooms, depending on the pattern of sonic reflections.
Connecting Speakers: In normal 2-channel operation, one stereo amplifier is used. For this configuration, the jumper bars on
the binding posts should be left in place and the switch on the back of the speaker should be set to “Four-Way Loudspeaker”.
The speaker cable can be connected to either the upper or lower binding posts. Connect the red (positive) amplifier post to the
red (positive) speaker post. Connect the black (negative) amplifier post to the black (negative) speaker post. Recommended
speaker wire size will depend on the distance from your amplifier to your speaker (see “Wire Length / Minimum Gauge
Requirements” chart).
Multi-Channel / Home Theater Installation
5.1 System - Consists of a front left, front right, surround left, surround right, center channel, and subwoofer channel. In a home
theater configuration, the center channel should be centered between the left and right front channels and as close to listening
height as possible, either above or below the screen (preferably below the screen). The surround channels should be placed
to either side of the listening area or behind the listening area at listening height.
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 - Has the same basic channels as a 5.1 system, with the addition of a left rear surround and right rear surround.
Connect the proper output on your home theater processor or receiver to the binding posts on your freestanding speaker using
normal polarity (red to red and black to black).
Subwoofer Amplifier Interconnect
The ID1 and ID1.15 are designed to be used with the A2 subwoofer amplifier (designed and built by Induction Dynamics).
The A2 subwoofer amplifier is designed to integrate with audio/video pre-amplifiers and receivers that have their own built-
in low-frequency crossover circuits, typically containing optional crossover frequency settings. If the crossover frequency is
selectable, the recommended setting for the ID1 and ID1.15 is 80 Hz with the subwoofer connected in reverse polarity (see
“Power Connection” section).
Using high quality interconnect cables with RCA type terminations, connect “SUBWOOFER OUT” on the audio/video pre-
amplifier or receiver to “IN” on the A2. You may adjust the subwoofer level using the control in the menu of the audio/video
pre-amplifier or receiver.
