What we know about the measurement:

Magnepan LRS is a passive panel that cost around 650 USD each.

  • Quality of the measurement data is high.
  • Origin of the data is ASR.
  • Format of the data is generated by a Klippel NFS .
  • Sensitivity: 82.2dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
  • -3dB (resp. -6db) point v.s. reference is at 165.5Hz (resp. 74.7Hz).
  • Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
  • Frequency deviation is 4.8dB over the same frequency range.
  • Directivity
    • Horizontal directivity is (-10.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
    • Vertical directivity is (-10.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
  • Tonality (Preference) Score
    • Note: The tonality (Preference) score does not make sense for panel speakers. Don't give too much credits to the value.
    • Tonality (Preference) Score is -0.32 and would be 5.01 with a perfect subwoofer.
      • Details: NBD: ON 0.728, LW 0.529, SP 0.431, PIR 0.433; SM: SP0.325, PIR0.191; LFQ 10.0, LFX 250Hz
    • Tonality (Preference) Score is 4.65 with an EQ and would be 7.01 with a perfect subwoofer and the same EQ.
      • Details: NBD: ON 0.556, LW 0.398, SP 0.342, PIR 0.342; SM: SP0.763, PIR0.75; LFQ 3.93, LFX 51Hz
