Installation
Moving the speakers
Remove all attached speaker cords and spikes in advance.
The speaker should be carried by two or three persons as
illustrated below. Walk carefully as you move the
speaker. Because the speaker is very heavy (about 58 kg),
be careful not to strain your back while moving the
speaker.
Take care not to touch the speaker domes.
Points to keep in mind before starting the
installation
To achieve the best sound quality, we recommended that
you install the system in the manner described below.
For details, see "Positioning the speakers" on page 10.
• The speaker-to-speaker separation should be less than
or equal to the speaker-to-listener distance.
• Position the speakers at least 1 meter away from any
side walls.
• The listening position should be at least 1 meter away
from the rear wall. It would be very helpful to place a
highly absorbent material (such as rug or drapery) on
the rear wall behind the listening position.
• Place a thick rug between the speakers and the listening
position to eliminate floor reflections.
• Do not put anything between the speakers and the
listening position. Obstacles such as large tables, chairs,
TVs, and other furniture are especially liable to affect
the sound quality adversely.

Attaching the spikes
Attach the supplied spikes to the bottom of the speaker.
There are three inserts per speaker; two in front and one at
the rear. For safety reasons, this procedure should be
done by two or more persons.
Attach the supplied stop nuts to the spikes themselves in
advance.
1
Tip the front or rear of the speaker upwards to
reveal an insert for the spike.
Take care not to touch the speaker domes or the
super-tweeter on top of the speaker cabinet.
2
Screw a spike (attached with a stop nut) into the
threaded insert.
Be sure to screw the spike at least 7 to 8 mm into the
insert.
Stop nut
3
Adjust the speaker height, and then tighten the
stop nut with a wrench.
After adjusting the height of the speaker by screwing
or unscrewing the spikes (see "Height Adjustment" on
page 7), tighten the stop nut firmly.
4
Lower the speaker to the floor.
If the speaker is on a hard wood floor, use the
supplied spike pad under the spike to protect the
floor. This procedure need not be done on a carpet.
5
Repeat steps 1 to 4 for the remaining spikes.
Repeat this procedure until all three spikes are
attached to the speaker.
Notes
• When tipping or lifting the speaker, be careful not to strain
your back.
• Be careful not to catch your fingers or feet under the speaker.
• After attaching the spikes, be careful not to lower the speaker
onto your feet or hand.
