Snell CR7 Speaker System HT Labs Measures
Satellite Sensitivity: 87 dB from 500 Hz to 2 kHz
This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the CR7 satellite (purple trace) and Basis 150 subwoofer (blue trace). The passive loudspeaker was measured with grille at a distance of 1 meter with a 2.83-volt input.
The CR7’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.20/–3.15 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +1.81/–3.14 dB from 200 Hz to 10 kHz. The –3-dB point is at 85 Hz, and the –6-dB point is at 68 Hz. Impedance reaches a minimum of 3.98 ohms at 230 Hz and a phase angle of –48.19 degrees at 96 Hz.
The Basis 150’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 36 Hz and the –6-dB point is at 32 Hz. The upper –3-dB point is at 216 Hz using the Ext Crossover input.—MJP
