Revel Performa F52 Speaker System:
HT Labs Measures: Revel Performa F52 Speaker System
L/R Sensitivity: 87.5 dB from 500 Hz to 2 kHz Center Sensitivity: 89.5 dB from 500 Hz to 2 kHz Monopole Surround Sensitivity: 85.5 dB from 500 Hz to 2 kHz Dipole Surround Sensitivity: 86 dB from 500 Hz to 2 kHz This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the F52 L/R (purple trace), B15A subwoofer (blue trace), C52 center channel (green trace), M22 monopole surround (red trace), and S30 dipole surround (brown trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and were scaled for display purposes. The F52's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.44/–2.37 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 41 Hz, and the –6-dB point is at 25 Hz. Impedance reaches a minimum of 4.10 ohms at 2.2 kHz and a phase angle of –40.85 degrees at 208 Hz. The C52's listening-window response measures +1.53/–2.03 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +1.68/–1.68 dB from 200 Hz to 10 kHz. The –3-dB point is at 67 Hz, and the –6-dB point is at 56 Hz. Impedance reaches a minimum of 3.44 ohms at 351 Hz and a phase angle of –19.23 degrees at 48 Hz. The M22's listening-window response measures +1.25/–2.42 dB from 200 Hz to 10 kHz. The –3-dB point is at 44 Hz, and the –6-dB point is at 39 Hz. Impedance reaches a minimum of 5.23 ohms at 177 Hz and a phase angle of –71.17 degrees at 80 Hz. The S30's three-face averaged response in dipole mode measures +1.29/–5.30 dB from 200 Hz to 10 kHz. The –3-dB point is at 81 Hz, and the –6-dB point is at 69 Hz. Impedance reaches a minimum of 3.89 ohms at 186 Hz and a phase angle of –48.87 degrees at 96 Hz. The B15A's close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 20 Hz and the –6-dB point is at 18 Hz. The upper –3-dB point is at 270 Hz with the filter switch set to out and the contour switch set to Music.—MJP
