HT324A Operating Manual
Figure 9: The above curves illustrate the effect of the 'bass tilt', 'bass roll-
off' and 'bass',' mid' and 'treble' level controls on the free field response,
measured at 2 m
Figure 10: The upper curve group shows the horizontal directivity
characteristics of the HT324A in its horizontal configuration measured
at 2m. The lower curve is a 1/6 octave power response measurement,
derived from 144 directivity measurements.
