Two-Channel (Stereo)
Installation
Speaker Placement
For two-channel stereo listening it is recommended that you place your ID1.15s 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 ID1.15s 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 Stereo Mode
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
ID1.15 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 chart on page 4).
