Connecting multiple subwoofers to make a Plane Wave Bass Array™
A 4-way column loudspeaker installation is possible for large systems, for example O 410 and O 870. Hardware is
available for the main loudspeaker to be mounted on top of the subwoofer with a tilting function. The
subwoofers should be calibrated so that they smoothly extend the bass response of their respective main
loudspeaker (see Acoustical Controls and Calibration section). The LFE channel should be connected to all of the
subwoofers, using XLR "Y" cables, and the signal level adjusted at the source by -9.5 dB or +0.5 dB so that the
reproduction level (at 0 or +10 dB) is consistent with the main channels.

location and will probably be different for the same subwoofer type positioned in different locations in the same
