Three-box cardioid systems
A three-box array, with two forward-
facing and one facing to the rear,
gives additional acoustic output
to the front but with slightly less
optimal rear attenuation.

back three-box array.
Figure 12 is a front view of a
stacked three-box array. Use the
bottom subwoofer as the rear-
facing one.
