Installation
≥ Each speaker must be carried and installed by at least two people.
≥
Do not touch the speaker units. Doing so may result in incorrect audio quality.
≥
Place the speakers at approximately the same distance from the listening position.
≥
The speakers produce bass sound from the bass reflex ports on the rear as well as from the front. Install the speakers at least
5 cm (2
z ) away from the walls so that they do not cover the bass reflex ports on the rear.
≥ Keep the amplifier or any other device and the speakers at least 1 cm (
13
/
32
z ) away from each other.

For optimum position
The quality and volume of the bass sound, sound localisation performance, sound ambience, and other factors that determine the
audio quality vary depending on the installation location of this unit, listening position, room conditions, and other factors. Refer to
the information below when installing the speakers.
Determining an installation location.
≥ Each speaker has a mass of approximately 35 k g (78 lbs). Check that the installation location is strong enough to bear this
mass.
≥
If you need to secure the speakers against tipping over, consult an installation specialist. The strength of the floor and wall must
be verified. (
> 15)
≥ Put the speakers on a flat safe surface.
If the speakers wobble when placed, use the spacers. (
> 13, 15)
≥
To minimize the gap in audio quality between the left and right speakers, install them so that acoustic conditions (reflection and
absorption of sound) around them are the same.
Adjusting the distances between the rear of the speakers and the walls
If you install the speakers close to a wall or in a corner, the bass sound will be more powerful; however, when the speakers are
too close to it, sound localisation performance and sound ambience may deteriorate. If this occurs, adjust the distance between
the speakers and the front wall, which should be between 30 cm (12
z ) to 60 cm (24 z ). (Please note that the distance between the
speakers and the side walls should be greater than 60 cm (24 z ).)
≥
Do not drag the speakers by force. Doing so may damage the speaker and the floor.
Adjusting the angle of the speakers
Angle the front side of the speakers toward the listener. Following these steps will help the speakers deliver more precise sound
localisation.
Adjusting the acoustics of the room and speaker layout
Depending on the room environment (including the size and shape of the room, distance to the walls and reverberation level),
certain sounds may be exaggerated or suppressed, making them difficult to hear. In such cases, adjusting the reverberation level
by moving the speakers, changing your listening position or covering the walls and windows with thick curtains may help resolve
the problem.
≥
The spikes may enhance the audio quality. ( > 12)
