HT Labs Measures

Satellite Sensitivity: 86.5 dB from 500 Hz to 2 kHz

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

The Imagine Mini’s listening- window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +0.93/–1.19 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +1.40/–1.38 dB from 200 Hz to 10 kHz. The –3-dB point is at 80 Hz, and the –6-dB point is at 71 Hz. Impedance reaches a minimum of 4.03 ohms at 284 Hz and a phase angle of –61.64 degrees at 132 Hz.

The SubSeries 1’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 134 Hz with the Crossover switch set to External (LFE Input).—MJP
