SUB2
POWERED BASS MODULE
Product Overview
A powered, portable bass module, the Sub2 subwoofer combines with virtually any portable PA and delivers low-end performance down to 37 Hz. It’s unique 10″ × 18″ high-excursion neodymium RaceTrack driver allows for an ultra-slim enclosure, delivering a performance that rivals a traditional 15″ woofer without the cumbersome size, freeing up room in your vehicle and on the stage. Compared to the Sub1 subwoofer, Sub2 is the more powerful subwoofer option for the Bose L1 Pro32 system, combining seamlessly via single-cable SubMatch connectivity. You can stack multiple Sub2 subwoofers for even more low-end — or to unleash Cardioid Mode for directional bass. With a Sub2, you get a subwoofer that easily fits onstage — and effortlessly fills up the dance floor.

Connections and Controls
-
Standby Button: Press the button to power on the Sub. The LED will illuminate white while the Sub is on.
-
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 a 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.
-

Architect and Engineer Specification
The sub shall be a single-driver, subwoofer with internally supplied power
amplification and active equalization for multiple operating modes as follows:
The sub shall consist of a modular 10″ x 18″ (254 mm x 457 mm) RaceTrack low-
frequency driver mounted in a ported bass enclosure.
The nominal horizontal beamwidth of the loudspeaker shall be omnidirectional,
with a –10 dB rear rejection when in Cardioid mode. The nominal vertical
coverage shall be 0°. The power amplification for transducers shall be
supplied by an integral single-channel onboard amplifier providing 1000 W for
the low-frequency transducer.
The onboard digital mixer shall consist of two input channels. Each input
channel shall provide two combination XLR or 1/4″ TRS connectors (line-level)
with selectable equalization presets for low-pass filter and L1 optimization.
Each input channel shall also provide an XLR balanced line-level connector
with selectable equalization presets for full bandwidth, high-pass filter, and
S1 Pro optimization. The digital mixer shall provide master output level
control and phase/pattern control for the positive polarity, negative
polarity, and Cardioid mode.
The sub shall provide multi-pin SubMatch input and output connectors to
receive power from L1 Pro32 and send power to another Sub1/Sub2 with a Bose
SubMatch cable.
The enclosure of the sub shall be constructed of high-impact polypropylene and
birch plywood. The sub shall provide a pole-mount M20 threaded insert for use
with the Bose Sub1/Sub2 Adjustable Speaker Pole. The sub shall provide four
interlocking feet on each side for stacking with one other Sub2.
The sub’s dimensions shall be 27.3″ H × 12.5″ W × 21.7″ D (694 mm × 317 mm ×
551 mm). Its net weight shall be 50.7 lbs (23.0 kg).
The sub shall be the Bose Sub2 portable powered bass module.
