American Acoustic Development C Series-3G - Manual (Page 5)

Placement
Two Channel Stereo Application
For stereo listening, you may choose any one pair of bookshelf or floor standing model.
The size of speakers should be determined by the size of your living space so that they
can provide sufficient volume. The two loudspeakers should be placed an equal
distance from your listening position.
Bookshelf systems will also benefit from placement on stands or shelves. The
C Series-3G stands are designed to match the bookshelf speakers functionally and
aesthetically.
Placing the loudspeakers in corners or against a wall will result in the strongest (but
not necessarily the most accurate) bass. For the best stereo imaging, we recommend
that the systems be placed so that the high frequency transducers are as close as
possible to the ear level of a seated listener.
Every room has different acoustic characteristics and people have different tastes in
sound. You should experiment to find out the placement position that satisfy your
personal tastes.
Home Theater Application
To get the best surround sound from your C Series-3G speakers, we recommend to
position the speakers at the same distance from the listening position.
The centre speaker, however, may be moved closer, but not beyond the straight line
connecting the two front speakers. The rear speakers may also be closer to listening
position than the front speakers to suit the configuration of your room.
Notes:
- Do not place the centre or rear speakers farther away from the listening position
than the front speakers.
- When mounting the rear speakers on side walls perpendicular to the listening
position they should be placed 60-90cm above the listener's ear level at sitting down
position.
