Now,
tmless
you
floor
is
absolutely
perfectly
flat,
you
will
need
to
make
slight
adjustments
to
the
spikes
so
that
the
Angelus
doesn't
wobble on them. Push back
and
forth
diagonally
(and
gently)
on
the
top
of
the
SPeaker, and
you'll
see
what
I mean. Adjust one
or
other
of
the
spikes
that
are
lined
up
in
the
direction
in
which
the
wobble hapPens,
tmtil
it
stops.
Now
you can
lock
the
spikes
in
place.
Take your
trusty
7/16" wrench
and,
while
securing
the
spike
with
one hand
so
it
doesn't
turn,
tighten
the
lock
nut
up
against
the
enclosure.
Snug
is
just
fine,
and
you'll
need
to
do
all
four.

If
you have followed
the
setup
instructions
in
order,
your
setup
is
now
canplete.
Spend sane time
sitting
and
listening
to
a
variety
of
music through
your
new
system. Notice
how
different
the
quality
of
each
recording
is,
how
easy
it
is
to
pick
out
individual
voices
and
instrunents
even
in
canplex
material,
how
warm
and
rich
the
sotmd
is,
and
how
totally
tmfatiguing
the
Angeli
are
to
listen
through. With
well
recorded
rwsic,
the
magic
of
the
Angelus becanes
evident
in
its
ability
to
reproduce
warm,
natural
tonal
balance
while
at
the
same time
presenting
a
realistic
image
of
the
space
that
the
DllSic
was
recorded
in.
If
you
don't
mind a
little
'tech
talk',
here's
some
general
advice
on
getting
the
most
out
of
your system,
either
now
or
in
the
future.
Amplifiers
'!be
JOb
of
the
power
amplifier,
whether
it
is
a
separate
component
or
part
of
a
rece1ver,
is
basically
twofold.
First,
to
make
the
signal
caning
fran
your
source
(record,
CD,
whatever)
strong
enough
(and
without
distortions
of
any
kind)
to
cause
sotmd
to
cane
out
of
the
speakers.
Second,
it
must
be
able
to
overcane
the
constantly
changing
electrical
conditions
(called
'impedance'
or
'load')
that
a speaker
presents
to
an
amplifier.
Although
it
is
beyond
the
scope
of
this
manual
to
discuss
why,
it
is
a
fact
that
sane
amplifiers
do
this
better
than
others.
Here
are
some
things
to
look
for
when
canparing
power
amplifiers
and
receivers:
>High
instantaneous
current
capacity.
>
Wide
full
power bandwidth.
> Constant damping
factor
over
the
widest
possible
frequency
range.
>
Low
transient
intetmOdulation
distortion
(TIM).
This
is
nn1ch
more important
than
the
usually
quoted hm:monic
distortion.
'!be Angelus
presents
quite
an easy
load
for
an
amplifier
to
drive;
the
mininun
impedance
is
5.8
obns, and occurs
at
8.5
kiloHertz.
How
IllJCh
power you
will
need depends
on
how
loud you
like
to
play
your
DlJsic.
For
soft
to
nonnal volune
levels,
20
to
50
watts
will
be
just
fine.
If
you
really
like
to
'wick
it
up'
sanetimes,
then
the
more power
available,
the
better.
Most
damage
to
speakers
happens because
of
insufficient
power
being
available
for
the
volune
level
being
demanded. With
percussive
music,
it
is
not
uncoom:m
that
the
peak power
required
will
exceed
the
average power by a
factor
of
ten
or
more!
To
illustrate
the
point,
let's
say
your
50
watt
amplifier
is
cruising
along
delivering
7
watts
average
to
the
Angelus. Along canes a
