Connecting and setting up | |||
To configure cardioid subs, stack two identical modules as seen to the left, connect the top sub module to an L1 Pro32 via a SubMatch cable or an external source and A/C power. Next set the top sub to positive polarity and the bottom sub to cardioid mode by pressing and holding the polarity button until the CARDIOID LED is illuminated. | |||
Make sure that the LEVEL settings are matched across the sub modules as mismatching them will skew the performance of cardioid mode. Once this setup has been completed a 10dB down point will be present directly behind the sub stack. This performance will be extremely beneficial if your performance includes any large resonant instruments such as an upright bass or a drum set. | |||

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. | Note: Bose does not claim Cardioid mode increases the Sound Pressure Level (SPL) in front of the subwoofers.
