Center Sensitivity:
91 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the SuperSat 3 satellite (purple trace), SuperSat 3C center channel (green trace), and ForceField 3 subwoofer (blue 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 SuperSat 3’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.83/–3.30 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 181 Hz, and the –6-dB point is at 158 Hz. Impedance reaches a minimum of 4.71 ohms at 374 Hz and a phase angle of –41.12 degrees at 254 Hz.

The SuperSat 3C’s listening-window response measures +2.49/–3.11 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.58/–4.18 dB from 200 Hz to 10 kHz. The –3-dB point is at 178 Hz, and the –6-dB point is at 156 Hz. Impedance reaches a minimum of 4.65 ohms at 374 Hz and a phase angle of –41.44 degrees at 247 Hz.

The ForceField 3’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 34 Hz and the –6-dB point is at 29 Hz. The upper –3-dB point is at 134 Hz with the Lowpass Crossover control set to maximum.—MJP
