Satellite Sensitivity: 87.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 90 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Quintet 5 satellite (purple trace), Quintet 5 center channel (green trace), and SW-110 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 satellite’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +4.38/–2.60 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 120 Hz, and the –6-dB point is at 103 Hz. Impedance reaches a minimum of 5.03 ohms at 374 Hz and a phase angle of –37.41 degrees at 247 Hz.

The center’s listening-window response measures +3.01/–1.37 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.54/–2.52 dB from 200 Hz to 10 kHz. The –3-dB point is at 107 Hz, and the –6-dB point is at 98 Hz. Impedance reaches a minimum of 5.08 ohms at 408 Hz and a phase angle of –38.04 degrees at 260 Hz.

The SW-110’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 33 Hz and the –6-dB point is at 30 Hz. The upper –3-dB point is at 103 Hz with the Lowpass control set to maximum. —MJP
