Recommended
Power
We recommend amplifiers and receivers rated from a range
of
20-150 watts
with our compact systems, 20-200 watts with our tower models. For playing at
consistently room-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
80-150 watts for sustained program
material-as,
for instance, with organ pedal tones
of
long duration, or minutes-
long subterranean special effects
in
movies.
Be
aware amplifiers with equal power rating may not play equally loud. Those
with higher dynamic power ratings, better satisfy the power requirements.
Some have protective circuitry that curtails power available
in
demanding
situations.
E.
Cabinet
Care
Cabinets have varying materials and finishes, including wood veneers, vinyl,
anodized aluminum and high gloss "poly lacquers" and should be treated as
you would furniture with similar finishes. Dust lightly with a soft cloth; avoiding
abrasives. If necessary, wipe carefully with a cloth slightly dampened with
glass cleaner to remove heavy soil.
F.
Grilles
and
Ports
A lint brush does a good job
of
cleaning grilles. Removable 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
domes will permanently damage tweeters.

IN
CASE OF PROBLEMS
A. Lower power if a speaker begins to sound distorted, or seems to be missing
certain frequencies, to check first to see whether playing at somewhat lower
volume seems to clear up the problem. As we noted under "Recommended
Power," 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. Isolate the problem to the electronics or the speakers and, if the speakers, to
specific speakers. Interchange the speaker wire connections on your amplifier
or receiver between channels, so that the left speaker is connected 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,
irrespective
of
the channel to which it's
connected-and
after changing the
connecting
wire-chances
are the speaker itself probably needs service.
