Getting Started
Height Adjustment
Adjust the length of the spikes so that the center of the
main tweeter dome is exactly equal to ear level at the
listening position. For safety reasons, this operation
should be done by two or more persons.
The design of the speaker assumes an ear height of 97 cm
to 102 cm while sitting on a chair or couch at the listening
position. Refer to the illustration below and adjust the
height of the spikes accordingly.
Ear position Main tweeter position
You can also tilt the angle of the speaker as shown in the
illustrations below. However, because of the possible
effects of floor reflections, we recommend positioning the
speaker as level with the floor as possible.
Downward tilt Upward tilt
1
Tilt the front or back of the speaker to raise the
spike off the floor.
Take care not to touch the speaker domes or the super-
tweeter on top of the speaker cabinet.
2
Adjust the length of the spike by screwing or
unscrewing it.
Keep the spike threaded at least 7 mm to 8 mm into
the insert. The height of the speakers can be varied by
approximately 13 mm.
3
Repeat steps 1 to 2 to adjust the remaining spikes.
Adjust the height of the speaker so that the center of
the main tweeter dome is directed in a straight line at
the point where the ears will be.
4
Tighten the stop nuts with a wrench to secure the
spikes.
Tighten the stop nuts until they are firmly against the
speaker cabinet.

If you want to lower the height of the speaker even more
Remove the stop nuts from spikes. Tightening the spikes without
the stop nuts allows you to lower the height by another 6 mm.
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.
Adjusting the orientation of the
super-tweeter
The super-tweeter on top of the speaker cabinet
reproduces high frequencies of up to 100 kHz.
Because of its high directivity, the super-tweeter can be
adjusted laterally (horizontally), though the lateral angle
is normally set at 0 degree.
For details, see “Super-tweeter” on page 12.

Note
The super-tweeter grille is not removable since the dome material
is extremely fragile. If you attempt to remove the grille, you may
damage the super-tweeter.
