Satellite Sensitivity: 84 dB from 500 Hz to 2 kHz

Center Sensitivity: 85 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the CG3 satellites (purple trace), 10S subwoofer (blue trace), and CG23 center channel (green trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The CG3’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.78/–2.93 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 96 Hz, and the –6dB point is at 73 Hz. Impedance reaches a minimum of 4.69 ohms at 232 Hz and a phase angle of –38.94 degrees at 154 Hz.

The CG23’s listening-window response measures +4.89/–2.14 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +4.92/–2.50 dB from 200 Hz to 10 kHz. The –3dB point is at 54 Hz, and the –6dB point is at 47 Hz. Impedance reaches a minimum of 4.31 ohms at 216 Hz and a phase angle of –33.69 degrees at 4.1 kHz.

The 10S’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 30 Hz and the –6dB point is at 27 Hz. The upper –3dB point is at 127 Hz using the LFE input.—MJP
