Editing Subwoofer (section)

=====Delay-shaded array=====
A long line of subwoofers placed horizontally along the front edge of the stage can be delayed such that the center subwoofers fire several milliseconds prior to the ones flanking them, which fire several milliseconds prior to ''their'' neighbors, continuing in this fashion until the last subwoofers are reached at the outside ends of the subwoofer row ([[beamforming]]). This method helps to counteract the extreme narrowing of the horizontal dispersion pattern seen with a horizontal subwoofer array. Such delay shading can be used to virtually reshape a loudspeaker array.<ref name=Engebretson2007 />
