** This is selected automatically when using the SubMatch cable connection with an L1 Pro32
* S1 Pro: 150 Hz
**  Press and hold LINE OUT EQ button for 4 seconds. The HPF LED will illuminate green. To deactivate the S1 Pro EQ, press and hold for
four seconds
*LINE IN EQ set to LPF: 100 Hz<br>Use this with third-party full-range and mid-high speaker systems
 
=== SubMatch Connection Signal Flow ===

====L1 Pro 32 SubMatch Output====
* Full range audio signal
* AC Power
 
====Sub1/Sub2 SubMatch Pass Thru====
* Full range audio signal (unaffected by any settings on the Sub1/Sub2)
* AC Power
 
====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


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).
;LINE OUT EQ (FULL RANGE or HPF)
* Line Out 1 LINE OUT EQ is FULL RANGE or HPF depending on the setting of the Line Out EQ button
* Line Out 2 LINE OUT EQ is FULL RANGE or HPF depending on the setting of the Line Out EQ button


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 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>
