The left and right line-level outputs from a mixer feed the left and right inputs of the first subwoofer. The
inputs are summed in mono to play in the subwoofer, but this does not affect the full-range or high-pass
outputs, which remain fully stereo. The left and right full-range line-level outputs of this subwoofer feed
the left and right inputs of the second subwoofer. The high-pass outputs or full-range outputs of either
subwoofer could feed the other powered loudspeakers in your system.
The left and right line-level outputs from a mixer feed the inputs of a pair of subwoofers. Their respective
full-range outputs feed the inputs of another pair of subwoofers. The high-pass outputs from the second
set of subwoofers then feed the inputs of a pair of powered loudspeakers.
NOTE: It is highly recommended that you use straps to secure your loudspeakers for stacked scenarios
such as this one. Be sure to loop a strap through each handle going down each side of the cabinet setup,
as shown above.
