3. High Frequency Level (dB)
Control
Provides a shift in the output level
of the tweeter or overall high-frequency
response (active above approximately
2.5kHz). The options are -1dB, 0dB,
and +1dB.
4. High Frequency Tilt Control
Adds a "tilt" to the high frequency
response. The tilt will become active
above approximately 8kHz (depart
from nominally flat response) and will
increase to 3-4dB at 20kHz. This will
offer an improved high frequency
response for installations where the
primary listening position is located
significantly off the tweeter axis (for an
effect almost like adding "toe in"
towards the listening position). The
added high frequency contour helps to
offset perceived reduction of high
frequency response for off axis listeners
due to the increase in directivity of the
system (tweeter beaming) above 8kHz.
5. Listener Axis Control
All loudspeakers sound best when the
listener is positioned at optimum
angles relative to the speaker place-
ment. This is a fixed angle for most
loudspeakers, but the I20/I30 provides
compensation for much greater place-
ment flexibility. The listener axis con-
trol, used in conjunction with the
placement of the speaker, can obtain
excellent results in a very wide range
of circumstances. This control opti-
mizes system response for installations
where the listening positions are lower,
higher, or directly on level with the
tweeter. This switch will be active in the
network transition regions between the
woofer and tweeter (in the I20) and the
midrange and tweeter (in the I30).
• Select the “high” (up arrow) setting
if the speaker is mounted so that the
listener is at tweeter level or above.
• Select the on axis setting if the
listener position is located directly
on axis with the tweeter level.
• Select the “low” (down arrow)
setting if the speaker is mounted so
that the listener is below tweeter
level.
Note
In some circumstances, such as when the
speaker is to be mounted high on the wall
towards the ceiling, it may be desired to
invert the speaker in order to place the
tweeter axis closer to the listener’s ear
level. The Listener Axis Control will also
optimize these inverted speaker installa-
tions. Refer to the Note on page 13 and
the Optimizing Performance (page 18)
section for additional information.
6. Low Frequency Boundary
Compensation Control
Compensates for less-than-ideal speak-
er placement near adjacent walls or
boundaries.
• Select the off setting if the speaker
is mounted at least four feet away
from adjacent walls or boundaries.
• Select the on position if the speaker
is less than four feet from one (or
possibly two) or more adjacent
walls or boundaries. In the on posi-
tion, system output is reduced
below approximately 400Hz to off-
set the increased low frequency
support due to the boundary.
Note
Refer to the Optimizing Performance section
on page 18 for more information about the
front panel controls.
