IN COMBINATION WITH
SPEAKERS
The frequency characteristics of the S-51W
combined with small-size speakers are shown
below. As shown in these figures, the low
frequency range is improved.
• These special characteristics are obtained
in an echoless chamber. The effect of an
additional S-51W in an ordinary listening
room is better than the chart indicates
when positioned adequately.
• With playback of Dolby* Digital,
establishment of a special channel for the
subwoofer is recommended; and with
playback of LFE (Low Frequency Effect:
sound effect like the rumbling of the earth,
whose purpose is to intensify the force of
the video), the S-51W is especially effective.

INSTALLATION
Speaker Installation
• Subwoofer Installation Criteria
1 Left speaker
2 Right speaker
3 Recommended installation range for
the subwoofer
4 Listening position
The subwoofer plays back the bass in
monaural, making use of the fact that the
human ear is not very sensitive to the direction
of low-pitched sound. Because of this, the
subwoofer can be installed almost anywhere.
If it is installed too far away, however, the
sound from the other speakers may become
unnatural.
