This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the V-5.1 L/R (purple trace), V-5.2-C center channel (green trace), V-S surround (red trace), and V-SW10 subwoofer (blue trace). All passive loudspeakers were measured with grilles at a dis- tance of 1 meter with a 2.83-volt input and scaled for display purposes.

The V-5.1’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.15/ –2.61 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 61 Hz, and the –6-dB point is at 56 Hz. Impedance reaches a minimum of 4.65 ohms at 210 Hz and a phase angle of –54.56 degrees at 112 Hz.

The V-5.2-C’s listening-window response measures +5.19/–2.62 dB from 200 Hz to 10 kHz. An aver- age of axial and +/–15-degree horizontal responses mea- sures +5.50/–2.94 dB from 200 Hz to 10 kHz. The –3-dB point is at 54 Hz, and the –6-dB point is at 44 Hz. Impedance reaches a min- imum of 4.53 ohms at 216 Hz and a phase angle of –65.05 degrees at 110 Hz.

The V-S’s three-face averaged response in dipole mode measures +3.41/–8.05 dB from 200 Hz to 10 kHz. The –3-dB point is at 102 Hz, and the –6-dB point is at 84 Hz. Impedance reaches a minimum of 4.60 ohms at 216 Hz and a phase angle of –66.46 degrees at 112 Hz.

The V-SW10’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 29 Hz and the –6-dB point is at 27 Hz. The upper –3-dB point is at 126 Hz with the Low-Pass Filter control set to maximum.—MJP
