Specifications
A
coomon
question
is
whether
the
speakers
should
be
set
up
along
a
long
or
short
wall
in
the
room.
In
smaller
rooms, where
the
longest
distance
between opposing
walls
is
14
feet
or
less,
setup
along
the
long
wall
will
probably
give
the
best
results.
In
larger
rooms,
setup
along
a
short
wall
is
preferable.
Placement
Relative
to
the
Listening
Position
In
phase-coherent
systems
(as
in
life
in
general),
TIMING
IS
OF
'lHE
ESSmCE.
And
in
matters
Pertaining
to
sotmd, time
translates
directly
into
distance,
because
sound
moves
through
air
at
a
given
SPeed.
In
the
introduction
to
this
section,
we
hinted
at
the
fact
that,
while
smooth
tonal
balance
can
be
achieved
over
a
wide
range
in
your
room,
the
magic
of
nearly
holographic
imaging
can
only
occur
at
one
point
in
space.
In
order
to
reproduce
a
stable
and
lifelike
stereo
image
with
the
Angelus,
two
things
are
necessary:
1>
The
distance
from
each
Angelus
to
your
listening
position
should
be
the
same.
2>
'Ibe
tilt
of
each
speaker
should
be
the
same,
and
adjusted
according
to
the
instructions
that
follow.
For
convenience
in
explanation,
we
will
refer
to
your
listening
position
as
a
chair.
<>
Find
the
point
at
ear
height
at
the
center
of
your
chair,
and mark
it
with
a
piece
of
masking
tape.
<>
Using a
tape
measure,
find
the
distance
from
this
point
to
the
floor,
and
jot
the
figure
down
somewhere.
<>
Measure
the
distance
from one Angelus
to
your mark.
<>
Now
measure
the
distance
to
the
other
Angelus,
and
move
it
toward
or
away
from you
until
it
is
the
same
distance
as
the
first
Angelus.
As
for
the
height
and
tilt,
take
a peek
at
Figure
2.
It
shows a
line
drawn
perpendicular
to
the
back
of
the
Angelus from
the
point
that
is
halfway between
the
woofer and
the
tweeter.
The
object
is
to
have
this
line
point
right
at
your
ears
when
seated
in
your
chair.
Now,
there
is
no
such
line
on
the
Angelus
cabinet,
and you
wuld
have
thought
we
were
nuts
if
we
had
put
one
there.
So,
instead,
we
will
use
the
top
of
the
pedestal
as
our
sight-line,
which happens
to
be
parallel
to
this
line,
and
apply
a
'fudge-factor'
to
make
it
work.
If
you
are
using
the
Angelus
without
spikes,
you
cannot
make
this
adjustment;
so
sorry.
The magic
line
for
you
is
36
inches
off
the
floor.
For
an
Angelus
with
spikes,
this
line
is
37
inches
off
the
floor.
If
the
floor-to-ear-height
measurement you
made
just
a minute ago
was
37
inches
(give
or
take
a
half
inch),
you
may
skip
the
next
four
instructions.
The
rest
of
us
will
be
adjusting
the
tilt
of
the
Angelus by
raising
or
lowering
the
spikes.
For
ear-heights
below
37",
you
will
lower
both
front
spikes;
for
heights
above
37",
lower
both
rear
spikes.
<>
Using your measuring
tape,
find
the
point
on your
chair
that
is
7
inches
below
the
ear-height
mark, and mark
it
with
a
piece
of
tape.
<>
Sighting
along
the
top
edge
of
the
pedestal,
adjust
the
tilt
of
the
speaker,
so
that
the
point
just
marked on your
chair
lines
up
directly
the
ledge.
<>
Repeat
this
procedure
for
the
other
Angelus.
