What we know about the measurement:

JBL COL800 is a passive columns speaker that cost around 500USD each .

  • Quality of the measurement data is low .
  • Origin of the data is JBL.
  • Format of the data is a GLL file .
  • Sensitivity: 94.5dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 74.5dB.
  • -3dB (resp. -6db) point v.s. reference is at 115.0Hz (resp. 103.0Hz).
  • Reference level is normalised to 0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.7dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-80.0°, 80.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-20.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is 2.32 and would be 5.99 with a perfect subwoofer.
