A configuration of subwoofers that delivers even coverage throughout the listening area in front of the array with cancellation behind it. This configuration eliminates the "power alley" and nulls that result from the standard left/right configuration.

This is a MAPP Online drawing of the standard configuration of subs left and right of the stage This array uses 16 boxes with 4 double stacks of Meyer 700HP subs per side. Notice the cancellation nulls, power alley and equal coverage forward and back. CLICK HERE.

This is a MAPP Online drawing of a cardioid Sub Array using 14 boxes. Each box is a double stack of Meyer 700HP subs where the top box is firing backward, polarity reversed and delayed 2.5ms. 5 double stacks face fwd/back and each side of the array it turned out 90 degrees. This array uses 6 drive lines using delay to create a digital arc in the array. Notice the width of the coverage without nulls or power alley. This configuration has leakage on stage but has generous width. CLICK HERE
