Line Inputs: Analog input for connecting an L1 Pro or another line-level audio source. Compatible with XLR, TRS balanced, and TS unbalanced cables.
-
Line Outputs: Use an XLR cable to connect the line-level output to a loudspeaker.
-
submatch Thruput: Connect an additional Sub bass module with a SubMatch cable. Up to two Sub1 or Sub2-powered bass modules can be powered by a single L1 Pro32 via SubMatch connection.
-
Power Input Cover: Prevents simultaneous use of the SubMatch Input and Power Input. Slide the cover to reveal the power input that is needed for setup.
-
SubMatch Input: Connect the Sub to an L1 Pro32 with a SubMatch cable.
-
Power Input: IEC power cord connection.

-
Line Input EQ: Select between an optimized EQ for an L1 Pro or a multipurpose LPF when using Line Inputs. Press the button to switch EQ settings. The corresponding LED will illuminate white while selected.
-
Signal/Clip Indicator: The LED will illuminate green when a signal is present and will illuminate red when the signal is clipping or the Sub is entering limiting. Reduce the level or signal volume to prevent signal clipping or limiting.
-
Level Control: Adjust the level of audio output. The Level Control does not affect the Line Outputs. The 12 o’clock position is recommended when in use with an L1 Pro32.
-
Phase/Pattern Button: Adjust the polarity of the Sub. Press the button to switch polarity. The corresponding LED will illuminate white while selected. Also allows access to Cardioid mode when using two identical Sub modules.
Connecting Power
There are two ways to connect a Sub to power: connecting to a power outlet or
connecting to an L1 Pro32 with a SubMatch cable. The Power Input Cover
prevents simultaneous connection of both power inputs. Only one of the two
power connections should be used at a time. If connecting directly to a power
outlet, slide the Power Input Cover to the left, concealing the SubMatch
Input. If connecting to an L1 Pro32 with a SubMatch cable, slide the Power
Input Cover to the right, concealing the Power Input.
WARNING: Do not alter, modify, or remove the sliding cover over the power input of the Sub1/Sub2. There is uninsulated, dangerous voltage within the product enclosure that may present a risk of electrical shock.
Connecting Directly to a Power Outlet
-
Plug the power cord into the Power Input.
-
Plug the other end of the power cord into a live electrical outlet.
Note: Do not power on the Sub until after you’ve connected your sources. -
Press the Standby Button. The LED will illuminate white while the Sub is on.
Connecting to an L1 Pro32 with a SubMatch Cable
Phase/Pattern
-
Plug the SubMatch cable into the SubMatch Input on a Sub1/Sub2.
-
Plug the other end of the SubMatch cable into the SubMatch Output of the L1 Pro32.
-
Plug the power cord into the Power Input on the L1 Pro32.
-
Plug the other end of the power cord into a live electrical outlet.
Note: Do not power on the L1 Pro or the Sub until after you’ve connected your sources. See the L1 Pro32 owner’s guide at PRO.BOSE.COM for more information about connecting sources to an L1 Pro32. -
Press the Standby Button on the L1 Pro32 then press the Standby Button on the Sub. The LEDs will illuminate white while the L1 Pro and Sub are on.
Note: Press and hold the Standby Button for 10 seconds to reset the Sub to factory settings. When using two Subs via SubMatch cable connection, first turn on the Sub connected directly to the L1 Pro32, then turn on the second Sub.
AutoOff/Low-power Standby
After four hours of no use, the Sub will enter AutoOff/Low-power Standby mode
to save power. To wake the Sub from AutoOff/Low-power Standby mode, press the
Standby Button.
Note: Disable AutoOff/Low-power Standby mode by pressing and holding the
Phase/Pattern Button and Line Output EQ button simultaneously for 10 seconds.
Enable AutoOff/Low-power Standby mode by repeating this step. Disabling
AutoOff/Low-power Standby mode will result in higher energy usage when the Sub
is not in use.
Inputs and Outputs
-
Line Input
Analog input for connecting an L1 Pro or another line-level audio source. Compatible with XLR, TRS balanced, and TS unbalanced cables. Use Line Input 1 (Left) and Line Input 2 (Right) together for stereo applications. -
Line Output
Use an XLR cable to connect the line-level output to a loudspeaker. Use Line Output 1 (Left) and Line Output 2 (Right) together for stereo applications.
Settings
Phase/Pattern
Adjust the polarity of the Sub. Press the button to switch between positive
polarity (+) and inverted polarity (–). The corresponding LED will illuminate
white while selected. Choose the polarity that sounds best for your
application.
Cardioid Mode
Cardioid mode is for use with a stack of two identical Sub modules, which
allows for most of the sound energy to be focused in front of the Sub stack
while reducing the sound energy that is generated behind the Sub stack. Press
and hold the button for four seconds to select CARDIOID. The LED will
illuminate white while selected. Press and hold again to switch back to +.
Cardioid mode should only be used in a stacked configuration of two identical
Sub modules, with the top Sub facing the coverage area and the bottom Sub
facing the non-coverage area. Set the Phase/ Pattern of the top Sub to + and
the Phase/Pattern of the bottom Sub to CARDIOID. When adjusting the level of
the stacked subs in Cardioid mode, be sure that the Level Control is set to
the same position on both Subs. See the below diagrams for Sub stack
orientation and coverage patterns.
Level
Adjust the level of audio output from the Sub. Begin with the Level Control
set to a low setting and increase the level until the Signal/Clip Indicator
illuminates green. The Level Control does not affect the Line Outputs. The 12
o’clock position is recommended when in use with an L1 Pro32. If using two
Subs with a single L1 Pro, it is recommended that the Level Control is set to
the same position on both Subs.
Line Input EQ
Change the EQ of both Line Inputs by pressing the Line Input EQ button until
the corresponding LED for your desired EQ illuminates white. Use L1 to apply
an input EQ optimized for L1 Pro products; use LPF to apply a low-pass filter
to the inputs. When a Sub is connected to an L1 Pro32 with a SubMatch cable,
the Line Input EQ will be fixed to L1.
Line Output EQ
Change the EQ of both Line Outputs by pressing the Line Output EQ button until
the corresponding LED for your desired EQ illuminates white. Use FULL for full
frequency or HPF to apply a high-pass filter to the outputs. Note: If
using the Sub with an S1 Pro, press and hold the Line Output EQ button for
four seconds to enable an EQ specifically optimized for use with an S1 Pro.
The HPF LED will illuminate green. To deactivate the S1 Pro EQ, press and hold
for four seconds.
Sub1/Sub2 Orientation
WARNING: Do not place the equipment in an unstable location. The
equipment could become unstable leading to a hazardous condition, which could
result in injury.
CAUTION: Do not stack more than two Subs together. Only stack two Subs of
the same model. For horizontal configurations, adjust the logo by rotating it.
For stacked configurations, the Sub includes four interlocking feet that will
attach to another Sub of the same model. When stacking Subs horizontally,
always make sure the feet lock together before connecting power and sources.
Using the Pole-mount Insert with an S1 Pro
WARNING: The pole-mount M20 threaded insert on the Sub1 and Sub2 is
designed to support a pole of up to 1.3 meters (51 inches) with a Bose S1 Pro
mounted on the pole. Do not use the Sub1 or Sub2 with a pole exceeding 1.3
meters (51 inches) in height or a loudspeaker weight that exceeds 7.1
kilograms (15.7 pounds). Using a pole/loudspeaker combination that exceeds
either of these limits or creates an unstable mounting scenario may lead to a
hazardous condition that could result in injury. The Sub1/Sub2 includes a
pole-mount M20 threaded insert. The insert is compatible with the Bose
Sub1/Sub2 Adjustable Speaker Pole accessory, designed for use with the Bose S1
Pro system (for more information, see the Adjustable Speaker Pole owner’s
guide at PRO.BOSE.COM).
Care & Maintenance
Cleaning Your Sub
Clean the product enclosure using only a soft, dry cloth. If necessary,
carefully vacuum the grille of the Sub.
CAUTION: Do not use any solvents, chemicals, or cleaning solutions
containing alcohol, ammonia, or abrasives.
CAUTION: Do not use any sprays near the product or allow liquids to spill
into any openings.
