2. Your sitting position will be more than ten feet (3 meters)
away from your loudspeakers
The width of your room divided by 3.6 will give you the
distance from the side wall to the center of the front baffle
of your speakers.
We suggest that you start with the speakers aligned directly at
you. Then open them slowly until you get the best soundstage
without losing too much center-stage definition. For most case,
the left speaker should align toward your left shoulder and the
right speaker should align toward your right shoulder. Opening
them will improve your image width and closing them will
improve your image center definition.
Room Treatment
The Fidelio gives its best performance in an average-furnished
domestic listening room. It requires a minimum of room
treatment. Before investing in room treatment we strongly
recommend you to take the time to listen and get familiar with
your speakers. The Fidelio has proved to be a standalone
loudspeaker that rarely needs to be acoustically corrected. A
good room placement is usually the most effective approach.
You should always start to position your speaker without any
treatment. If speaker positioning cannot solve standing waves
or reverberation problems read the following. The principal
design factor for internal acoustics of a room, in addition to
shape and size, is the control of sound absorption and
reflection.
The total absorption required to give optimum reverberation is
inherent to your room characteristics, i.e., which surfaces are
absorptive or reflective, the area of these surfaces and the
selection of acoustical materials.
A flutter echo is a rapid (usually regular) succession of
reflected pulses resulting from a single pulse. They can be
easily identified by clapping your hands while walking in the
room. They are frequently located at the ceiling corners or at
the center of the ceiling-wall intersections. If flutter echos are
prominent, please consult your dealer to get proper assistance
on that matter.
The reverberation in the room is the resulting tendency for
sound level in the room to persist after direct sound ceases.
The optimum reverberation time for a room depends upon
room volume, sound frequency, and the type of sound or
reproduced music. The Fidelio performs at its best in lively
listening rooms.
Overly damped room will be detrimental to the Fidelio
performance. Optimum reverberation time (at 500 to 1,000
Hz) should be between 0.4 and 0.6 second.
Standing waves are reflections from opposing parallel surfaces
resulting in serious peaks in the reverberation-time / frequency
curve. In properly proportioned rooms, resonances can be
effectively reduced and standing waves practically eliminated
by introducing numerous sound treatment devices.
