Three-Box Cardioid Systems
A three-box array, with two forward-facing subwoofers and one rear-facing subwoofer, gives additional acoustic output to the front
but with slightly less optimal rear attenuation.
Figure 6 is a top view of a back-to-back three-box array.
Figure 7 is a front view of a stacked three-box array. Use the bottom subwoofer as the rear-facing one.
