Morel SoundSpot Music Theatre 2 Ultra Speaker System 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 SP-2 satellite (purple trace) and the PSW10 subwoofer (blue trace). The passive loudspeaker was measured with its grille at a distance of 1 meter with a 2.83-volt input.
The SP-2’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +3.44/–2.65 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +3.46/–3.38 dB from 200 Hz to 10 kHz. The –3-dB point is at 161 Hz, and the –6-dB point is at 139 Hz. Impedance reaches a minimum of 4.69 ohms at 326 Hz and a phase angle of –69.06 degrees at 20 kHz.
The PSW10’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 28 Hz. The upper –3-dB point is at 127 Hz with the Frequency control set to maximum.—MJP
