What we know about the measurement:

JBL Control 25T is a passive outdoor speaker that cost around 350USD for a pair .

  • Quality of the measurement data is low .
  • Origin of the data is JBL.
  • Format of the data is a GLL file .
  • Sensitivity: 110.6dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 90.6dB.
  • -3dB (resp. -6db) point v.s. reference is at 150.0Hz (resp. 128.0Hz).
  • Reference level is normalised to 0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.4dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-60.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-40.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Tonality (Preference) Score is -0.09 and would be 4.28 with a perfect subwoofer.
      • Details: NBD: ON 0.629, LW 0.613, SP 0.625, PIR 0.612; SM: SP0.099, PIR0.0; LFQ 1.728, LFX 150Hz
    • Tonality (Preference) Score is 1.69 with an EQ and would be 5.77 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.454, LW 0.458, SP 0.551, PIR 0.491; SM: SP0.476, PIR0.296; LFQ 2.126, LFX 127Hz
  • Note: Data provided by JBL in GLL format is highly variable, beware. It ranges from excellent to surprising
