AV Receiver Reviews

• Satellite Sensitivity: 84 dB from 500 Hz to 2 kHz

• Center Sensitivity: 88 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the SBS-01 satellite (purple trace), PB10-NSD subwoofer (blue trace), and SCS-01 center channel (green 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 SBS-01's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.82/–2.98 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 84 Hz, and the –6-dB point is at 68 Hz. Impedance reaches a minimum of 7.48 ohms at 166 Hz and a phase angle of –49.67 degrees at 91 Hz.

The SCS-01's listening-window response measures +2.75/–2.78 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.88/–2.57 dB from 200 Hz to 10 kHz. The –3-dB point is at 101 Hz, and the –6dB point is at 80 Hz. Impedance reaches a minimum of 9.00 ohms at 174 Hz and a phase angle of –50.22 degrees at 98 Hz.

The PB10-NSD's close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 39 Hz and the –6-dB point is at 30 Hz. The upper –3-dB point is at 138 Hz using the only input.-MJP
