What we know about the measurement:

JBL SLP14 is a passive surround that cost around 280 USD each.

  • Quality of the measurement data is low.
  • Origin of the data is JBL.
  • Format of the data is a GLL file .
  • Sensitivity: 99.2dB (avg. 100Hz-1kHz for 2.83V estimated at 1m) . Sensitivity computed at the measurement distance (10m) over the same frequency range: 79.2dB.
  • -3dB (resp. -6db) point v.s. reference is at 92.5Hz (resp. 80.0Hz).
  • Reference level is normalised to 0.0dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 2.4dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-80.0°, 80.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-50.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Note: The tonality (Preference) score does not make sense for surround speakers. Don't give too much credits to the value.
    • Tonality (Preference) Score is 3.22 and would be 6.47 with a perfect subwoofer.
      • Details: NBD: ON 0.503, LW 0.486, SP 0.588, PIR 0.517; SM: SP0.78, PIR0.685; LFQ 0.931, LFX 82Hz
    • Tonality (Preference) Score is 5.37 with an EQ and would be 8.39 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.255, LW 0.239, SP 0.295, PIR 0.24; SM: SP0.909, PIR0.891; LFQ 0.931, LFX 73Hz
