Satellite Sensitivity: 89.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the SE 1 satellite (purple trace) and SE SUB subwoofer (blue trace). The passive loudspeaker was measured with its grille at a distance of 1 meter with a 2.83-volt input.

The SE1’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.34/–2.63 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +2.52/–2.13 dB from 200 Hz to 10 kHz. The –3-dB point is at 61 Hz, and the –6-dB point is at 55 Hz. Impedance reaches a minimum of 4.17 ohms at 232 Hz and a phase angle of –55.52 degrees at 106 Hz.

The SE SUB’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 26 Hz and the –6-dB point is at 24 Hz. The upper –3-dB point is at 218 Hz using the LFE input.—MJP
