REL Acoustics R-328 Subwoofer HT Labs Measures
This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the R-328 subwoofer (blue trace).
The R-328’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 30 Hz and the –6dB point is at 28 Hz. The upper –3dB point is at 103 Hz using the LFE input. The response reaches a maximum of +6.65dB at 46 Hz.—MJP
