Figure 4. The upper curve group shows the horizontal directivity
characteristics of the 1031A in vertical configuration measured at 1 m.
The lower curve is a 1/3 octave band power response, measured in an
IEC approved reverberation chamber.
Figure 5. The curves show the effect of the bass tilt, treble tilt and
bass roll-off controls on the free field response.
