What we know about the measurement:
LD Systems DDQ15 is a active liveportable speaker that cost around 1800USD each .
- Quality of the measurement data is medium .
- Origin of the data is Vendors-LD Systems .
- Format of the data is .
- -3dB (resp. -6db) point v.s. reference is at 47.5Hz (resp. 45.0Hz).
- Reference level is normalised to -0.0dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 1.5dB over the same frequency range.
- Directivity
- Horizontal directivity is (-20.0°, 20.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-30.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Tonality (Preference) Score is 4.2
and would be 6.1 with a
perfect subwoofer.
- Details: NBD: ON 0.47, LW 0.59, SP 0.73, PIR 0.65; SM: SP0.78, PIR0.67; LFQ 1.94, LFX 41Hz
- Tonality (Preference) Score is 5.3
with an EQ and would be 7.2 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.41, LW 0.46, SP 0.6, PIR 0.51; SM: SP0.91, PIR0.87; LFQ 1.92, LFX 40Hz
- Tonality (Preference) Score is 4.2
and would be 6.1 with a
perfect subwoofer.
