=== Cardioid Mode ===
[[File:Sub Cardioid Mode.jpg|thumb|Cardioid Mode]]
 
Stack two Sub1 or Sub2 subwoofers in Cardioid Mode for focused, directional performance with reduced rear-firing bass energy (-10 dB SPL). This steers the bass out front, and reduces feedback. This is particularly useful when you have resonant instruments on the stage (e.g., kick drum, upright bass).
 
Note: Bose does not claim Cardioid mode increases the Sound Pressure Level (SPL) in front of the subwoofers. The main benefit is that it reduces the SPL behind the subwoofers.
