L/R Sensitivity: 85.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 90.5 dB from 500 Hz to 2 kHz

Surround Sensitivity: 89.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the M16 L/R (purple trace), B10 subwoofer (blue trace), C25 center channel (green trace, corrected for boundary gain), and S16 surround (red trace, corrected for boundary gain). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The M16 listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +0.73/–2.33 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 57 Hz, and the –6dB point is at 50 Hz. Impedance reaches a minimum of 5.05 ohms at 160 Hz and a phase angle of –41.51 degrees at 96 Hz.

The C25’s listening-window response measures +0.73/–3.93 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +1.17/–4.14 dB from 200 Hz to 10 kHz. The –3dB point is at 86 Hz, and the –6dB point is at 67 Hz. Impedance reaches a minimum of 4.79 ohms at 200 Hz and a phase angle of –47.18 degrees at 98 Hz.

The S16’s listening-window response measures +0.85/–3.91 dB from 200 Hz to 10 kHz. The –3dB point is at 71 Hz, and the –6dB point is at 59 Hz. Impedance reaches a minimum of 4.91 ohms at 179 Hz and a phase angle of –45.91 degrees at 98 Hz.

The B10’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 31 Hz and the –6dB point is at 29 Hz. The upper –3dB point is at 145 Hz with the Low Pass Crossover control set to maximum.—MJP
