In some cases, none-symmetric arrays have to be used especially when the arrays are arranged in blocks of 4. In these cases, the pro-
duced coverage is always biased towards one direction, but strategic selection of placement can help shape the coverage to the specific
need. As can be seen in the examples below, placing a rear-facing subwoofer at the bottom of an array is the least effective. Rear-facing
subwoofers can be placed at the top of an array to keep energy off the ceiling.
