This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the B&W CM10 (purple trace). The passive loudspeaker was measured with the grille at a distance of 1 meter with a 2.83-volt input.

The CM10’s listening-window response (a five-point average of axial and ±15º horizontal and vertical responses) measures +2.40/–2.78 dB from 200 Hz to 10 kHz. An average of axial and ±15º horizontal responses measures +2.67/–5.97 dB from 200 Hz to 10 kHz. The –3-dB point is at 49 Hz, and the –6-dB point is at 37 Hz. Impedance reaches a minimum of 3.72 ohms at 115 Hz and a phase angle of –69.15º at 69 Hz. —MJP
