HT Labs Measures

Satellite Sensitivity: 87 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (corrected for on-wall boundary gain and employing close-miking of all woofers) frequency response of the Min 21 satellite (purple trace) and X300 subwoofer (blue trace). The passive loudspeaker was measured with grille at a distance of 1 meter with a 2.83-volt input.

The Min 21’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.01/–4.99 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses (in horizontal mode) measures +2.50/–4.78 dB from 200 Hz to 10 kHz. The –3dB point is at 168 Hz, and the –6dB point is at 143 Hz. Impedance reaches a minimum of 6.31 ohms at 144 Hz and a phase angle of –53.61 degrees at 100 Hz.

The X300’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 35 Hz and the –6-dB point is at 32 Hz. The upper –3-dB point is at 129 Hz with the Crossover Frequency control set to maximum.—MJP
