Satellite Sensitivity: 87 dB from 500 Hz to 2 kHz

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

The MilleniaOne’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.15/–1.46 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses in horizontal center mode measures +1.90/–2.10 dB from 200 Hz to 10 kHz. The –3-dB point is at 124 Hz, and the –6-dB point is at 107 Hz. Impedance reaches a minimum of 4.51 ohms at 277 Hz and a phase angle of –60.56 degrees at 162 Hz.

The Millenia 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 156 Hz with the Cut-Off Frequency control set to maximum.—MJP
