Attaching the cushions
Attach four cushions to the base of the subwoofer, one at
each corner. The cushions prevent the subwoofer from
sliding, and dampen its vibrations.
Accessories

Installation
The Subwoofer is a virtually omnidirectional speaker, so it can
be installed in almost any location. For example, the Subwoofer
can be installed next to the component system (consisting of
an amplifier, tuner, cassette deck, etc.), or in a corner of the
room, etc.. The subwoofer’s deep-bass reproduction charac-
teristics are richest when the subwoofer is installed in a corner
or near a wall. Since the low-bass component in music is usu-
ally monaural, only one subwoofer is necessary to obtain a
sufficient stereo effect when used in combination with a ste-
reo music system.

Howling
If the Subwoofer is installed near an analog record turntable, a
howling sound may be generated. If this occurs, place the
Subwoofer farther away from the turntable or reduce the
Subwoofer volume (By rotating the VOLUME control
counterclock-wise). The howling phenomenon may also occur
due to cross interference with a cassette deck, compact disc
player, or Laserdisc player, although this is very rare. If sound
or picture seems to be distorted due to this reason, place the
Subwoofer farther away from other components or reduce its
volume.
Operation near a TV
If the Subwoofer is installed near a TV set, the TV reception
may be affected and interfered with color irregularities. Should
color irregularities observed on TV screen, separate the
Subwoofer from the TV until its reception becomes normal.
Caution
To assure ventilation, observe the follow-
ing points when installing the unit.
•Leave a distance of more than 10
cm between the Subwoofer back
and the surrounding wall(s).
Use special care not to cover the
heat sink with a curtain, etc. when
installing.
•Be sure to install the Subwoofer ver-
tically.
