This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the B&W Panorama’s left channel (purple trace) and center channel (green trace). The soundbar was measured with its grille at a distance of 1 meter.

The left channel’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures + 1.90 /– 9.39 decibels from 200 hertz to 10 kilohertz.

The center channel’s listening-window response measures +1.43/–6.68 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +1.18/–7.46 dB from 200 Hz to 10 kHz. The –3dB point is at 42 Hz, and the –6dB point is at 37 Hz.—MJP
