Atlantic Technology FS-7.0 Soundbar and SB-800 Sub HT Labs Measures

HT Labs Measures

L/R Sensitivity: 83.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 84.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the FS-7.0 left channel (purple trace), SB-800 subwoofer (blue trace), and FS-7.0 center channel (green trace). The passive loudspeaker was measured with the grille at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The left channel’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +3.12/–6.23 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 83 Hz, and the –6-dB point is at 76 Hz. Impedance reaches a minimum of 17.02 ohms at 4.9 kHz and a phase angle of –17.94 degrees at 3.4 kHz.

The center channel’s listening-window response measures +4.63/–8.55 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +4.64/–8.54 dB from 200 Hz to 10 kHz. The –3-dB point is at 83 Hz, and the –6-dB point is at 73 Hz. Impedance reaches a minimum of 5.94 ohms at 3.7 kHz and a phase angle of –60.05 degrees at 2.2 kHz.

The SB-800’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 42 Hz and the –6-dB point is at 36 Hz. The upper –3-dB point is at 131 Hz with the Low-Pass control set to maximum.—MJP
