D.
Recommended Power
We
recommend
amplifiers
and
receivers
rated
from
a
range
of
20-150
watts.
For
playing
at
consistently
space-filling
volume,
a
minimum
of
50
watts
is
usually
a
good
idea.
As
just
indicated
in
the
paragraph
above,
be
wary
of
driving
low-
powered
amplifiers
to
their
limits.
We
recommend
a
maximum
of
80-120
watts
for
sustained
program
mate-
rial-as,
for
instance,
with
organ
pedal
tones
of
long
duration,
or
minutes-long
subterranean
special
effects
in
movies.
Amplifiers
with
equal
power
rating
may
not
play
equally
loud.
Those
with
higher
dynamic
power
ratings,
better
satisfy
the
power
requirements.
Some
have
pro-
tective
circuitry
that
curtails
power
available
in
demanding
situations.
E.
Cabinet
Care
If
necessary,
wipe
the
cabinets
carefully
with a
slightly
dampened
cloth.
Do
not
use
solvents
or
any
abrasive
materials.
F.
Grilles and Ports
A lint
brush
does
a
good
job
of
cleaning
grilles.
The
grilles
can
be
taken
off
and
vacuumed
if
you
prefer.
If
need
be,
you
can
use
a lint
brush
to
clean
ports.
Avoid
touching
speaker
diaphragms.
Particularly,
pushing
in
the
tweeter
domes
will
permanently
damage
tweeters.

TROUBLESHOOTING
A.
Lower
the
volume
if a
speaker
begins
to
sound
distorted
or
seems
to
be
missing
certain
frequencies,
to
check
first if
playing
at
somewhat
lower
volume
seems
to
clear
up
the
problem.
It
can
be
especially
important
to
turn
down
the
volume
right
away
if
you
have
pushed
a
low-powered
amplifier
or
receiver
past
its
comfortable
limits.
B.
Determine
if
the
problem
is
caused
by
the
electronics
or
the
speakers
and,
if it
is
the
speakers,
which
specific
speaker.
Interchange
the
speaker
wire
connections
on
your
amplifier
or
receiver
between
channels,
for
example
by
connecting
the
left
speaker
to
the
right
channel,
or
vice
versa.
If
the
problem
shifts
to
the
other
speaker,
the
problem
is
not
in
the
speaker
but
in
the
electronics.
C.
Another
component-or,
very
often,
a
cable
or
connection
problem
between
components-may
be
at
fault.
If
the
problem
stays
in
the
same
speaker,
