INSTALLATION TIPS:
AMPLIFICATION AND POSITIONING
OF IL CREMONESE IN THE ROOM
There are countless questions about the proper interfacing
of Il Cremonese, but what we would like to emphasise is that
a project like this is not designed to be at its first with just a
specific type of amplification.
All we can say is that a state-of-the-art loudspeaker system
requires an amplification system that is just as state-of-the-art,
no matter what technology is used.
Regarding the position of the loudspeakers in a room, some
general advice can prove useful to obtain the maximum
performance possible:
1. the choice of the listening room and the speaker
position influence the performance of the whole
system. A room with an irregular shape is preferable;
this type of room improves the response in the
environment because it limits the formation of standing
waves;
2. rugs and curtains (without exaggerating) positively
influence the acoustic response, because they
contribute to the absorption of reflections and standing
waves that are created in the listening room;
3. there are no hard and fast rules for every environment.
A good approach to the issue of positioning Il
Cremonese in a room, however, is to virtually divide the
listening room into three equal parts, as shown by the
broken lines in figure 15.
At this point, position the speakers on the first of these
broken lines and well away from the side walls.
The listening position should be placed on the second
broken line, as shown in figure 15.
In this manner a good amount of air is guaranteed all
around the subjects involved in the stereo reproduction,
because the speakers can work freely while the listener
is not struck by the acoustic reflections that generate
near the walls and the corners of the room.
Figure 16 shows how the speakers should be angled
to converge towards the listening point, thus creating
the classic 'isosceles triangle' configuration.
This final adjustment, consisting of angling the
speakers literally towards the ears of the listener,
greatly improves the focus of the stereophonic image.
We are aware that many of our customers will not be able
to create these quasi-ideal listening conditions because
of objective problems connected with the organization
of space and furniture in a house; therefore we advise
positioning the Il Cremonese speakers away from the room
corners and keeping them at a distance of at least 100 cm
min. from the side and back walls. We also recommend
placing the two speakers at a distance of no less than 180 cm
from one another and between each Il Cremonese speaker
and the listening point.
During the very first listening occasions you might need to
change the distance between the speakers and between
each speaker and the listening position.
