Subwoofer Reviews

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the SB13-Ultra subwoofer (blue trace).

The SB13-Ultra’s close-miked response, normalized to the level at 80 hertz, indicates that the lower –3-decibel point is at 25 Hz and the –6-dB point is at 21 Hz. The upper –3-dB point is at 160 Hz with Low Pass & High Pass set to Disabled and EQ set to Disabled.—MJP
