Infinity Crescendo Series User Manual

When
the
speakers
are
moved
inward
(toward
each
other)
this
generally
achieves
better
focus
of
instruments
and
vocalists;
however,
moving
the
speakers
too
close
together
can
reduce
the
front-to-
rear
stage
effect
and
you
may
need
to
experiment
with
the
trade-off
between
focus
and
imaging.
If
your
listening
room
is
larger
than
average
and
yout
listening
position
is
relatively
far
from
the
speakers,
wider
placement
of
the
speakers
may
be
required
(approximately
10
feet
apart).
FIGURE 5 -
Suggested starting
placements for
Crescendo Series
speakers
Try angling the speakers inward for better
projection of midrange and high frequencies;
however,
do
not
angle
the
speakers
too
sharply
because
this
may
reduce
stereo
imaging
as
well
as
front-to-rear
depth.
The
exact
angle
of
toe-in
must
be
deter-mined
by
careful
experimentation.
There
is
no
formula
to
follow
because
rooms
differ
in
acoustics
and
the
listener's
position
may
vary
considerably. See Figure 6.
The toe-in angle for each speaker should be
exactly
the
same
for
best
sonic
results.
This
can
be
done
effectively
by
eye
or
by
using
a
tape
measure
or straight edge to measure the amount of toe-in
from a forward firing position.

FIGURE 6 — Angling Crescendo Series speakers.
Using
the
two
adjustable
front
feet
to
tilt
the
speakers
either
forward
or
rearward
may
enable
you
to
obtain
better
sound
balance
throughout
the
entire
middle
and
high
frequency
range.
The
feet
may
be
rotated
in
either
a
clockwise
or
counter-
clockwise
direction
to
obtain
the
proper
alignment
for
your
installation.
Rotating
the
feet
clockwise
will
tilt
the
speaker
rearward.
Rotating
the
feet
counter-
clockwise
will
tilt
the
speaker
forward.
Be
careful
not
to
tilt
the
speakers
too
far
forward
or
rearward
since
this
may
cause
them
to
become
unstable.
Aligning
your
speakers
with
a
slight
tilt
either
forward
or
rearward
will
help
“tune”
them
to
the
room
and
to
your
listening
position.
If
your
sitting
position
aligns
your
ears
on
a
plane
that
is
lower
than
the
midrange
and
tweeter,
you
may
wish
to
tilt
the
speakers
downward
so
the
acoustic
output
from
the
speakers
reaches
your
ears
on
a
direct
plane.
If
you
are
seated
in
a
position
that
directs
the
sound
toward
your
chest
or
shoulders,
it
may
be
necessary
to
tilt
the
speakers
slightly
rearward
so
the
acoustic
output
from
the
midrange
and
tweeters
reaches
your
ears
on
a
direct
plane.
Toe-in,
tilting
and
moving
the
speakers
closer
and
further
from
walls
and
corners
are
all
part
of
the
speaker
tuning
procedure.
Don't
be
afraid
to
experiment
as
this
will
result
in
the
best
sound.
If
a
specific
location
yields
satisfying
results
and
you
wish
to
continue
to
experiment
with
speaker
placement,
mark
the
ideal
location
so
you
can
always
return
to
it.
When installing your speakers, be very careful
to
keep
them
on
the
same
plane
(exactly
the
same
distance
from
the
front
wall).
It
is
advisable
to
use
a tape measure or a string to measure the exact
distance
the
speakers
are
located
from
the
front
wall.
Also
keep
the
fronts
of
the
speakers
aligned
so
they
face in exactly the same direction. See Figure 7.
