What we know about the measurement:
Hsu Research HB-1 MK2 is a passive bookshelves speaker that cost around 218USD for a pair .
- Quality of the measurement data is high .
- Origin of the data is ASR .
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 86.3dB (avg. 100Hz-1kHz for 2.83V measured at 1m)
- -3dB (resp. -6db) point v.s. reference is at 74.7Hz (resp. 58.6Hz).
- Reference level is normalised to -0.3dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 4.5dB over the same frequency range.
- Directivity
- Horizontal directivity is (-40.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-10.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.2
and would be 6.6 with a
perfect subwoofer.
- Details: NBD: ON 0.57, LW 0.48, SP 0.4, PIR 0.4; SM: SP0.88, PIR0.65; LFQ 0.52, LFX 52Hz
- Tonality (Preference) Score is 5.7
with an EQ and would be 7.7 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.49, LW 0.41, SP 0.35, PIR 0.32; SM: SP0.97, PIR0.93; LFQ 0.56, LFX 42Hz
