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).  
=== SubMatch Connection Signal Flow ===
[[File:Sub1 Sub2 io panel.jpg|thumb]]
====L1 Pro 32 SubMatch Output====
* Full range audio signal
* AC Power


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.
====Sub1/Sub2 SubMatch Pass Thru====
* Full range audio signal (unaffected by any settings on the Sub1/Sub2)
* AC Power


See the tutorial in the video below starting at 4:05.
====Sub1/Sub2 using a SubMatch port for input====
;LINE IN EQ (LPF or L1)
* The LINE IN EQ is automatically set to '''L1''' regardless of the position of the button

Sub1 and Sub2 have extruded aluminum heat sinks mounted to the backside of the I/O panel. This pulls heat out of the electronics and transfers some to the air moving through the acoustic volume of the sub and helps to cool.<ref>[https://www.facebook.com/groups/BoseL1/permalink/10159635582172446/?comment_id=10159637158957446 Bose Professional]</ref>
