What we know about the measurement:
Ascend Acoustics ELX Ribbon Horizon is a passive center that cost around 2800 USD
- Quality of the measurement data is high.
- Origin of the data is Ascend Acoustics.
- Format of the data is a set of 36 horizontal and 36 vertical measurements .
- Sensitivity: 87.6dB (avg. 100Hz-1kHz for 2.83V estimated at 1m)
- -3dB (resp. -6db) point v.s. reference is at 51.3Hz (resp. 36.6Hz).
- Reference level is normalised to -0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 1.9dB over the same frequency range.
- Directivity
- Horizontal directivity is (-60.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-20.0°, 30.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 6.24
and would be 7.9 with a
perfect subwoofer.
- Details: NBD: ON 0.378, LW 0.322, SP 0.388, PIR 0.319; SM: SP0.952, PIR0.913; LFQ 1.364, LFX 35Hz
- Tonality (Preference) Score is 7.12
with an EQ and would be 8.34 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.302, LW 0.264, SP 0.328, PIR 0.26; SM: SP0.961, PIR0.944; LFQ 1.192, LFX 27Hz
- Tonality (Preference) Score is 6.24
and would be 7.9 with a
perfect subwoofer.
