DB Audiotechnik AL90 is a passive toursound speaker .
- Quality of the measurement data is medium .
- Origin of the data is DB Audiotechnik.
- Format of the data is a GLL file .
- Sensitivity: 86.3dB (avg. 100Hz-1kHz for 2.83V measured at 10m)
- -3dB (resp. -6db) point v.s. reference is at 103.0Hz (resp. 67.0Hz).
- Reference level is normalised to 0.6dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.4dB over the same frequency range.
- Directivity
- Horizontal directivity is (-20.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-20.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 1.79
and would be 4.65 with a
perfect subwoofer.
