What we know about the measurement:

EV EVID-S4.2 is a passive bookshelves that cost around 240 USD for a pair.

  • Quality of the measurement data is medium.
  • Origin of the data is EV.
  • Format of the data is a GLL file .
  • Sensitivity: 99.0dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 79.0dB.
  • -3dB (resp. -6db) point v.s. reference is at 122.0Hz (resp. 106.0Hz).
  • Reference level is normalised to 0.4dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 3.3dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-40.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-30.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
