Genelec 1038AC, Operating Manual

Page: 4 / 4

Figure 5. The curves above left show the effect of the 'bass tilt', 'bass level'
and 'bass roll-off' controls on the free field response. The curves to the
right show the effect of the treble and midrange 'level' controls.
Figure 6. The curve group above shows the horizontal directivity charac-
teristics of 1038AC in its vertical configuration measured at 1m.
