3) Satellite Left-Right Phase Reversal
If the right satellite is reversed in phase from
the connections on the left satellite, you
will hear reduced bass and a “phasey” dif-
fused vocal image. If you suspect the sound
is not right and you cannot see any mark-
ings on the wire, try this simple test:
1. Stand half way between the two satellite
speakers.
2. Play some vocal music with the amplifier
or radio set to Mono.
3. Listen to the apparent placement of the
vocals.
4. Turn off the amplifier and reverse one of
the connections on the subwoofer.
5. Repeat the listening test with the same
setting of the volume control. When
the sound has a richer bass, is slightly
louder and the vocal image is
“focused” the satellites are working
together or “in-phase”.

Congratulations
A concealed PSW800 subwoofer installa-
tion frees you to use your tone controls,
play the system loudly and enjoy deep
extended bass, even if your satellite speak-
ers are small. When used with satellite
speakers that have substantial bass of their
own, the PSW800 tightens the deep tones
and augments the bass musically.
Listening at Higher Volumes
It requires more power to achieve a reason-
able volume of sound in a large room than
it does in a small room. It is possible (even
if you are not a teenager) to turn the vol-
ume so high that the amplifier
runs out of
power
. This creates “clipping” distortion. If
you are using an extremely powerful ampli-
fier it may be possible to hear clicking or
buzzing sounds from the subwoofer as it
tries to reproduce too loud a sound. If you
hear these sounds turn the volume down.
More typically you will hear clipping dis-
tortion through your satellite speakers.
Clipping distortion makes treble sound very
harsh and unmusical. When you hear harsh
sounding treble from any good speaker,
turn the volume down immediately! Those
harsh sounds are masking some much
more powerful ultra-high-frequency sound
spikes which will quickly damage any fine
loudspeaker. You are much less likely to
damage a speaker with a large amplifier
because it will be very loud indeed before
it produces any clipping distortion.
Cleaning
You can clean the speaker with a damp-
ened soft cloth or paper towel. If the speak-
er is mounted high up on the wall, use a
broom to gently brush it off.
