What we know about the measurement:
KEF CI250RRM-THX is a passive inwall that cost around 2500 USD each.
- Quality of the measurement data is high.
- Origin of the data is ASR.
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 86.6dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
- -3dB (resp. -6db) point v.s. reference is at 51.3Hz (resp. 30.8Hz).
- Reference level is normalised to 0.0dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.6dB over the same frequency range.
- Directivity
- Horizontal directivity is (-60.0°, 60.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-50.0°, 50.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Tonality (Preference) Score
- Note: The tonality (Preference) score does not make sense for inwall speakers. Don't give too much credits to the value.
- Tonality (Preference) Score is 3.15
and would be 5.17 with a
perfect subwoofer.
- Details: NBD: ON 0.64, LW 0.436, SP 0.236, PIR 0.307; SM: SP0.429, PIR0.0; LFQ 2.697, LFX 42Hz
- Tonality (Preference) Score is 5.73
with an EQ and would be 6.85 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.591, LW 0.448, SP 0.355, PIR 0.372; SM: SP0.872, PIR0.759; LFQ 2.694, LFX 26Hz
