depth well behind the speaker, excellent focus of instruments and voices
with proper vertical information and mid bass fill.
A Genesis loudspeaker system correctly set up, can and should provide
a soundstage that is wall to wall and with pinpoint focus, the speakers
disappearing completely on a recording containing such information.
4.4 Room Treatment
No room is perfect. To optimize your sonic presentation it may be helpful
to treat your room. Here are some guidelines:
Front walls. This loudspeaker is a dipole and
therefore there is sound coming from both the
front and the back of the speaker. How the front
wall (the wall you face while listening) is treated
or not treated is important. Generally speaking,
the Genesis loudspeakers prefer a live (hard
reflective) front wall to a dead (soft absorbent)
front wall.
By these terms we mean the amount of reflection
of sound. A typical wall of glass, brick, cement
or drywall material is a reflective surface. A
heavily curtained or sound-proofed wall would be
considered a "dead wall" or a non-reflective wall.
A normal thin curtain across a window causes
only a small amount of absorption.
Sidewalls. Because the speaker is a dipole it is
less sensitive to the sidewalls. However, as a
rule of thumb it is a good idea to keep the
speaker as far away from the sidewalls as is
practical. In some rooms, it may be helpful to
add some damping material or diffuser panels to
the point of first reflection. This is a point on the
sidewalls between the listener and the
loudspeaker. It is where the sound from the
loudspeaker first hits the sidewall, then bounces to the listener.
This reflection is undesirable because it is slightly delayed from the
original sound. This point on the sidewall can be easily determined
with the help of a second person and a mirror.
Sitting in your listening position, have an assistant hold a mirror up
on the sidewall. Move the mirror until you can see the tweeter. This
is the point of first reflection. A diffuser (see your audio dealer), an
