HT Labs Measures: Sonos SP100 Loudspeakers

L/R 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 SP100 L/R (purple trace) measured at a distance of 1 meter with a 2.83-volt input.

The SP100's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.52/–3.70 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 81 Hz, and the –6dB point is at 70 Hz. Impedance reaches a minimum of 4.91 ohms at 198 Hz and a phase angle of –37.44 degrees at 129 Hz.—MJP
