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 medium.
- Origin of the data is KEF.
- Format of the data is a GLL file .
- Sensitivity: 66.5dB (avg. 100Hz-1kHz for 2.83V measured at 1m).
- -3dB (resp. -6db) point v.s. reference is at 160.0Hz (resp. 65.0Hz).
- Reference level is normalised to 0.1dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 3.2dB over the same frequency range.
- Directivity
- Horizontal directivity is (-40.0°, 40.0°) between 1kHz and 10kHz. Angle computed for +/-6dB.
- Vertical directivity is (-50.0°, 40.0°) 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 3.06
and would be 6.2 with a
perfect subwoofer.
- Details: NBD: ON 0.491, LW 0.296, SP 0.3, PIR 0.276; SM: SP0.568, PIR0.243; LFQ 2.785, LFX 77Hz
- Tonality (Preference) Score is 6.61
with an EQ and would be 8.34 with a
perfect subwoofer and the same EQ.
- Details: NBD: ON 0.364, LW 0.197, SP 0.271, PIR 0.205; SM: SP0.952, PIR0.941; LFQ 2.733, LFX 36Hz
