Satellite 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 SuperZero 2.0 satellite (purple trace) and Super 8 subwoofer (blue trace). The passive loudspeaker was measured with grille at a distance of 1 meter with a 2.83-volt input.

The SuperZero 2.0’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +3.01/–3.03 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +3.23/–2.60 dB from 200 Hz to 10 kHz. The –3-dB point is at 110 Hz, and the –6-dB point is at 97 Hz. Impedance reaches a minimum of 6.23 ohms at 230 Hz and a phase angle of –40.53 degrees at 146 Hz.

The Super 8’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 38 Hz and the –6-dB point is at 34 Hz. The upper –3-dB point is at 210 Hz using the LFE input with the EQ switch set to Music.—MJP
