Getting Started

Unpacking

Check that you received the following items:

• Audio connecting cord (1)

• Speaker cord (2)

Installation

Since the human ear cannot detect the direction and
position where the bass sound being reproduced by a
woofer (below 150 Hz) comes from, you can install the
woofer wherever you like in your room. To obtain a
better bass reproduction, we recommend you to install
the woofer on a solid floor where the resonance is
unlikely to occur.
You can obtain a sufficient heavy bass reproduction
from a single woofer. However if you use a couple of
the woofers, you can obtain an even more effective
heavy bass reproduction.

Notes

• Always install the woofer vertically, keeping a few
centimeters from away the wall.

• Do not place an object on the woofer or sit on it.

• If the woofer is installed in the center of a room, the bass
could be extreamely weakened. This is due to the
influence of the standing wave of the room. If this
happened, move the woofer away from the center of a
room or eliminate the cause of the standing wave, by
installing a bookshelf on the wall, etc.
