Opalum Flow.1010 On-Wall Speaker System HT Labs Measures
This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Flow.1010 L/C/R (purple trace) and Stream.210 surround (red trace). All loudspeakers were measured at a distance of 1 meter and scaled for display purposes.
The Flow.1010’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.74/–2.23 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +1.10/–2.36 dB from 200 Hz to 10 kHz when operating horizontally. The –3-dB point is at 69 Hz, and the –6-dB point is at 59 Hz.
The Stream.210’s listening-window response with grille measures +1.42/–2.15 dB from 200 Hz to 10 kHz. The –3dB point is at 65 Hz, and the –6dB point is at 57 Hz. Please note that the response is +6.11 dB at 143 Hz.—MJP
