MB Quart Vera VS 1F Speaker System HT Labs Measures

HT Labs Measures: MB Quart Vera VS 1F Speaker System

Vera VS 1F L/R Sensitivity: 84.5 dB from 500 Hz to 2 kHz

Vera VS 1C Center Sensitivity: 87 dB from 500 Hz to 2 kHz

Vera VS 1B Surround 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 Vera VS 1F L/R (purple trace), Vera VS 1C center (green trace), and Vera VS 1B surround (red trace). All passive loudspeakers were measured at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The VS 1F's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +0.24/–2.20 dB from 200 Hz to 10 kHz. The –3dB point is at 38 Hz, and the –6dB point is at 34 Hz. Impedance reaches a minimum of 8.30 ohms at 216 Hz and a phase angle of –44.66 degrees at 82 Hz.

The VS 1C's listening-window response measures +0.88/–3.71 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +0.89/–4.55 dB from 200 Hz to 10 kHz. The –3dB point is at 55 Hz, and the –6dB point is at 46 Hz. Impedance reaches a minimum of 5.86 ohms at 205 Hz and a phase angle of –50.97 degrees at 96 Hz.

The VS 1B's listening-window response measures +0.72/–2.96 dB from 200 Hz to 10 kHz. The –3dB point is at 50 Hz, and the –6dB point is at 43 Hz. Impedance reaches a minimum of 4.43 ohms at 1.5 kHz and a phase angle of –53.26 degrees at 96 Hz.—MJP
