On-axis response at 1M with 1/3 octave smoothing.  Same as above but with 1/12 octave smoothing.
 Two curves, one at 1M distance / height and the other 1M distance with the microphone on the floor.
 These curves were taken at 1M distance in small increments from 24" to 48" high. Notice the
very uniform vertical response at such a short distance.
 1M distance at 66" height.  1M distance, on-axis versus off-axis (30 degrees horizontal).
