One need all three mics, 4133 for low noise on axis curves, 4135 for high accuracy and above 20kHz tests, and 4134 for reverb.Our ears detect a 0.3dB change within a 1/3 octave. That leaves 6 different sounding steps within each of many 1/3 octaves within the normally accepted +-1 dB band. Different sounds galore!
After I have measured and trimmed a loudspeaker system, I allways check with many different pieces of well known music.
If I do not like the balance of the music, I start all over again with measuring and adjusting, until I hit something better sounding...
