Sonos Sub
The Sonos Sub takes your audio experience to the next level when you add this wireless subwoofer to an
existing Sonos room.
• Instantly adds a dimension of deep bass impact to your audio listening experience.
• Allows placement anywhere because it’s wireless and compact—position it vertically or horizontally on
any floor surface.
Note: The Sonos Sub is designed for use with any amplified Sonos speaker, such as the Playbase. It is not
designed for use with unamplified Sonos speakers, such as the Connect™and ZP80. Make sure you
set up at least one amplifier Sonos speaker before adding the Sub.

network.
AC power (mains) input Use only the supplied power cord to connect to a power
outlet (using a third party power cord will void your
warranty). Be sure to use the proper power adapter for
your country. Push the power cord firmly into the Sub
until it is flush with the surface.
Adding the Sub to Sonos
You can easily add the Sonos Sub to an existing Sonos system.
• You can pair the Sub with any amplified Sonos speaker, such as the Play:5. You cannot associate it with
an un-amplified Sonos speaker such as the Connect or ZP80.
• The Sub is compatible with Sonos software versions 3.8 and later. Be sure to check for software
updates before adding the Sub to Sonos.
1. Carefully unpack the package contents
Caution:Subwoofers are heavy. Exercise caution when unpacking your Sonos Sub. Use the acoustic slot as a
handle to lift the Sub out of the box. (You should always bend your knees when lifting heavy objects
to avoid undue stress on your back.)
2. Choose a location for the Sub. It is designed to provide optimal sound wherever you place it.
• You can position the Sub either vertically or horizontally. If you are going to use the Sub horizontally on
a smooth floor, you can attach the 4 permanent felt feet (included with your Sub) to each of the corners.
See Attaching the feet for horizontal placement for more information.
Make sure at least one side of the
rectangular opening (acoustic slot) is
unobstructed.
• If you place the Sub vertically flush
against a wall, do not block the
front acoustic slot.
• If you place the Sub horizontally
on the floor, don’t put anything on
top of it. Leave at least 1”
clearance along the top of the Sub
if placing under furniture.

• The Sub is designed to be located on the floor. You can place it in a corner, against the wall, behind,
under, or next to any piece of furniture on any kind of floor surface.
Note: The Sub contains strong magnets. Don’t place the Sub near equipment that is sensitive to
magnetic fields.
3. Attach the power adapter and plug in the Sub. Be sure to push the power cord firmly into the Sub until it is
flush with the surface.
4. Choose one of the following options:
• Using the Sonos app on a mobile device: Select > Settings >Add a Player or Sub.
• Using the Sonos app on a Mac or PC: Select Add a Player or Sub from the Manage menu.
Press and release the Join button on the side of the Sub. 
The indicator flashes green and white while the Sub is
connecting.
To optimize your Sub’s performance, during the setup process you will be prompted to make some choices—
• If you are joining a Connect:Amp or ZP100, select the size of your stereo speakers (Compact, Bookshelf/
Ceiling or Floor.)
• Press Play to compare the volume of two test sounds, A and B, and then select No Difference, A is
louder or B is louder.
• Press Play to listen to a test sound, and then select the best level for the Sub.
You may be prompted to update the Sub after you add it to Sonos.
Note: After the Sub is associated with a Sonos speaker, you will not see it displayed separately in Rooms.
Any changes you make to that Sonos speaker (volume, mute, music selection) will also affect the Sub.
Attaching the feet for horizontal placement
If you are going to use your Sub placed horizontally on a smooth floor, the Sonos Sub includes four (4)
permanent felt feet you can attach to the corners of the unit. If you are laying the Sub down on a rug or using it
vertically, there’s no need to adhere the felt feet.
Note: The felt feet are not adjustable—a strong adhesive will keep them permanently attached to the Sub
once you apply them.

Sonos Sub 5
The Sonos logo appears on the front of the Sub—you will adhere the felt feet to the opposite side of the unit.
1. Lay the Sub down on a rug or on top of the Sub’s felt packing bag so the Sonos logo is facing down and
is not visible.
2. Place the enclosed guide on one corner of the unit and fold the flaps over the edge.

Got a new router?
If you purchase a new router or change your internet service provider (ISP), you’ll need to restart your Sonos
products after the router is installed.
Note: If you keep a Sonos product connected to your router and an ISP technician connects it to the new
router, then you’ll only need to restart your other Sonos products.

2. Reconnect all the power cords—if you keep a Sonos product connected to your router, start with that one.
The speaker status light turns solid white on each product when the restart is complete.
If you don’t have a Sonos product connected to your router, you’ll need to change your network password
in the Sonos app.
