Soundbar Reviews

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the S5451w-C2 Sound Bar (purple trace) and subwoofer (blue trace). The left channel was measured with grille at a distance of 1 meter.

The S5451w-C2’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures + 4.42 /– 3.56 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +4.72/–3.66 dB from 200 Hz to 10 kHz. The –3dB point is at 99 Hz, and the –6dB point is at 87 Hz.

The subwoofer’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 47 Hz and the –6dB point is at 32 Hz. The upper –3dB point is at 107 Hz.—MJP
