    • Sensitivity: 96.5dB (avg. 100Hz-1kHz for 2.83V estimated at 1m).
    • Sensitivity: 76.5dB computed at the measurement distance (10.0m) over the same frequency range.
  • -3dB (resp. -6db) point v.s. reference is at 106.0Hz (resp. 67.0Hz).
  • Reference level is normalised to 0.6dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 3.4dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-30.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
