• Surround Sensitivity: 89 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the 826 V L/R (purple trace), SW 800 V subwoofer (blue trace), CC 800 V center channel (green trace), and SR 800 V surround (red 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 826 V's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.13/–3.79 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 46 Hz, and the –6-dB point is at 38 Hz. Impedance reaches a minimum of 3.56 ohms at 114 Hz and a phase angle of –60.21 degrees at 70 Hz.

The CC 800 V's listening-window response measures +2.45/–2.25 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.13/–2.66 dB from 200 Hz to 10 kHz. The –3-dB point is at 74 Hz, and the –6-dB point is at 63 Hz. Impedance reaches a minimum of 4.42 ohms at 200 Hz and a phase angle of –47.36 degrees at 111 Hz.

The SR 800 V's three-face averaged response measures +2.62/–4.76 dB from 200 Hz to 10 kHz. The –3-dB point is at 84 Hz, and the –6-dB point is at 76 Hz. Impedance reaches a minimum of 4.43 ohms at 254 Hz and a phase angle of –42.49 degrees at 120 Hz.

The SW 800 V's close-miked response with the Boost switch on, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 39 Hz and the –6-dB point is at 37 Hz. The upper –3-dB point is at 110 Hz using the LFE input.—MJP
