Focal Dimension Soundbar System Review Test Bench

Test Bench


This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Dimension soundbar (purple trace) and the Dimension Sub (blue trace). The left channel was measured with the grille on, at a distance of 1 meter.

The Dimension soundbar’s listening-window response (a five-point average of axial and ±15° horizontal and vertical responses) measures + 8.04 /– 2.51 dB from 200 Hz to 10 kHz. An average of axial and ±15° horizontal responses measures +8.45/–1.83 dB from 200 Hz to 10 kHz. The –3-dB point is at 107 Hz, and the –6-dB point is at 94 Hz.

The Dimension Sub’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 35 Hz and the –6-dB point is at 33 Hz. The upper –3-dB point is at 91 Hz. Please note that the response is +5.87 dB at 44 Hz, which would typically make the level setting required for proper integration tricky at best in a system that provided these adjustments.—MJP
