What we know about the measurement:
Andersson HIS 2.1 is a passive center that cost around 20 USD
- Quality of the measurement data is low.
- Origin of the data is Misc.
- Format of the data is a set of 36 horizontal and 36 vertical measurements .
- Sensitivity: 76.4dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
- -3dB (resp. -6db) point v.s. reference is at 99.3Hz (resp. 59.1Hz).
- Reference level is normalised to 0.5dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.0dB over the same frequency range.
- Directivity
- Horizontal directivity is (-10.0°, 10.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 1.48
and would be 3.89 with a
perfect subwoofer.
