Frequency Response Curves: Anechoic Far Field above 200 Hz, Half-space Anechoic below 200 Hz.
Impedance: Voltage to Current Ratio, Free Field measurement
Off-Axis Frequency Response: 1/3 octave smoothed frequency response, normalised to On-Axis response.
Directivity Curve, Coverage Angle and Polar Diagram from computer processing on off-axis response curves.
