Installation using three subwoofers (recommended):
The performance of the cardioid configuration is better when 3 subwoofers are used together. The
units can be stacked on top of each other or laid side by side on the ground. If in a stack, the low-
est unit should face the rear. If laid side by side, the middle unit faces the rear.
As in the previous example with two subwoofers, the rearwards facing subwoofer is operated in
Cardioid Mode. The two forwards facing units are operated as normal without the Cardioid Mode
activated (e.g. two K Sub 1502 dp with the Cardioid Mode not selected). All of the subwoofers in
the configuration should be operating at the same level and with the same cut-off frequency to get
the best result.
Note:
Both subwoofers must be set to the same cut-off frequency. The cardioid preset of rear-facing
subwoofer must be activated.
Application example:
Only the rear-facing subwoofer is operated in Cardioid Mode. This applies regardless of whether
the two units are stacked on top of each other or laid side by side on the ground.
