Atlantic Technology PB-235 PowerBar Soundbar HT Labs Measures
This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the PowerBar 235 Sound Bar (purple trace). The left channel was measured with grille at a distance of 1 meter. As per the manufacturer’s instructions for our free-space measurements, the Bass control was set to +3, and the Treble control to +2.
The PowerBar 235 Sound Bar’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.25/–2.60 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 57 Hz, and the –6dB point is at 50 Hz.MJP
