Surround Sensitivity: 84.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Verus II Grand Tower L/R (purple trace), Bravus II 12D subwoofer (blue trace), Verus II Grand Center center channel (green trace), and Verus II Grand Bookshelf 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 Grand Tower’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.49/–3.36 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 49 Hz, and the –6dB point is at 35 Hz. Impedance reaches a minimum of 4.58 ohms at 114 Hz and a phase angle of –38.90 degrees at 73 Hz.

The Grand Center’s listening-window response measures +2.39/–3.55 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.04/–3.26 dB from 200 Hz to 10 kHz. The –3dB point is at 72 Hz, and the –6dB point is at 59 Hz. Impedance reaches a minimum of 4.88 ohms at 146 Hz and a phase angle of –40.27 degrees at 84 Hz.

The Grand Bookshelf’s listening-window response measures +1.37/–4.29 dB from 200 Hz to 10 kHz. The –3dB point is at 58 Hz, and the –6dB point is at 49 Hz. Impedance reaches a minimum of 5.91 ohms at 186 Hz and a phase angle of –33.19 degrees at 118 Hz.

The 12D’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 22 Hz and the –6dB point is at 18 Hz. The upper –3dB point is at 229 Hz using the LFE input.—MJP
