Ascend Acoustics CMT-340 SE2 is a passive bookshelves speaker that cost around 350USD each .
- 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: 90.6dB (avg. 100Hz-1kHz for 2.83V measured at 1m)
- -3dB (resp. -6db) point v.s. reference is at 77.6Hz (resp. 64.5Hz).
- Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
- Frequency deviation is 2.2dB over the same frequency range.
- Directivity
- Horizontal directivity is (-80.0°, 70.0°) 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 5.52
and would be 8.18 with a
perfect subwoofer.
