In a forward firing (FF) configuration of Wilson Audio Autobiography speakers, low frequency output in the 10 Hz to 75 Hz region is reduced by approximately 1.0 to 1.5 dB, while output between 75 Hz and 130 Hz increases by 1.5 to 2.0 dB. Switching to a rear firing (RF) configuration gives the inverse response, offering flexibility to accommodate unique room boundaries and overall listener preference.
