a stereo source with a distinct center image (e.g. solo instrument, human voice), through both channels. If the
image is not in the center carefully rotate the loudspeakers inward in small increments to bring the image in
precise center focus. Toe-in is rather delicate, and experimentation is necessary to achieve proper angle for your
listening situation. The optimum angle is usually 3-10 degrees inward
.
Once you are happy with the positioning of your speakers, it is important to ensure that they are completely
stable. For floor models it is essential that you use the accompanying spikes.
Room acoustics and corner treatment
Listening your Teresonic speakers in a properly set-up room can be a startling experience. The listening room is
the final link of the playback system, as important – or more important, than other components in the chain:
1)Turntable, CD or SACD player, 2)Interconnect cables, 3)Amplifier, 4)Speaker cables, 5)Loudspeakers, and
6)Listening room! Some simple and relatively inexpensive adjustments can lead to superb results as described in
the following chapter five.
Some of the sound you hear comes not from the actual speakers but from reflections from floor, ceiling and
walls. These reflections are dampened by objects such as furniture, plants and carpets. If the sound is bright,
soft items such as curtains and carpets can help. If the room has large window panes, drawing the curtains will
prevent reflections from the glass surfaces.
Both the amount and quality of the deep bass depend on the size and shape of the room and the position of
the speakers. If positioned near a side or back wall, this will accentuate the bass. A corner location will
accentuate it even more, but will also increase the reflections. The decision is yours, so experiment with
different positions to find which provides the ideal sound for you.
Damping with a sonically absorbent material on the side and rear walls near the speakers is strongly
recommended in order to get well balanced sound stage and image depth (see “Improve the sound stage and
image depth” section in the chapter five. In addition, it’s critical to control the first reflections of low frequency
sound, which normally occurs at the corners behind the loudspeakers. Placing Tube-Traps (available from
Acoustic Sciences Corp) at the room corners can significantly improve the quickness of bass transients (see
“Getting fast, tight, realistic bass” section in the chapter five.
