Sonos Sub Gen 3 with Sonos One speakers

The Sub can add deep bass to a single Sonos speaker or a stereo pair (sold separately).

Like its popular predecessor, it has two force-canceling woofers positioned face-to-face in the cabinet to deliver powerful, bass with minimal distortion. It also still has those glossy good looks. But the new version has increased memory and processing power for better performance now, and as it gets updated in years to come.

Convenient to set up

This sub is wireless, so it's easy to tuck neatly almost anywhere in the room. You can even place it flat on its back under the couch. You just need to be within reach of an AC outlet. Pairing it with your compatible components is easily done in the Sonos app.

Wireless Powered Sub

Sonos Sub (Gen 3): The Sonos Sub (Gen 3) is a wireless powered subwoofer, designed to add deep bass (down to 25 Hz) to your Sonos listening experience. The Sub works with a variety of Sonos speakers and components that support the new Sonos S2 operating system and S2 controller app.

  • Compatible Speakers: Works with the Sonos One, One SL, and Five; as well as older Sonos speaker like the Play 1, Play 3, and Play 5 (Gen 2).
  • Compatible Soundbars: Works with the Sonos ARC, Playbar, Playbase, and Beam.
  • Compatible Components: Works with the Sonos Amp.

Notes:

  • The Sonos Sub (Gen 3) is only compatible with Sonos products that support the new Sonos S2 operating system (OS) and S2 controller app (except for the Sonos Move, Port, and Connect).
  • The Sonos Sub (Gen 3) is not compatible with older "Legacy" Sonos products that only utilize the Sonos S1 operating system and the older S1 controller app.

Woofer & Amplifier Design: The Sonos Sub (Gen 3) features two force-canceling speakers (3" x 6" race-track shaped drivers) positioned face-to-face to provide deep, rich bass with no resonance from the cabinet. The speakers are powered by two Class-D digital amplifiers, perfectly tuned to match the speakers. The speakers are mounted into a unique cabinet that features an acoustic slot and dual acoustic ports that encircle the enclosure to enhance the Sub's performance.

Wired or Wireless Network Connection: The Sonos Sub (Gen 3) works on your home WiFi network with practically any 802.11b/g, 2.4GHz network capable router. It also works on SonosNet, a secure AES encrypted, peer-to-peer wireless mesh network dedicated exclusively for your Sonos system to reduce WiFi interference. In addition to its built-in SonosNet Wireless Mesh Network and WiFi, the Sub (Gen 3) is also equipped with one Ethernet port (10/100 Mbps). Use it to wire directly to your router to operate if WiFi is unstable, or use the Ethernet port to provide Internet accessibility to non-wireless devices if you're using a SonosNET Boost setup.

  • You cannot connect the Sonos system via both the SonosNet proprietary mesh network and WiFi; you will need to choose one. Sonos recommends using its proprietary SonosNet wireless mesh network over WiFi when applicable.
  • The Sonos proprietary mesh network will provide a more secure wireless connection with fewer interruptions for optimum performance.
  • WiFi is subject to greater interference from other WiFi and 2.4GHz devices on your network.
  • WiFi connectivity is not compatible with 5GHz (you will have to use the Sonos wireless mesh network in this case).

Simple Setup: Once you have positioned the Sub in the room, you can press the Join button on the side of the Sub (Gen 3) in order for the system to recognize it. During setup you will be prompted through the Sonos S2 Cotnroller app to set the subwoofer's level and phase. In some cases, you will be prompted to select the size of the stereo speakers (compact, bookshelf/ceiling, or floor) connected to the amplified player. If you move the Sub (Gen 3) to another room, you can easily reconfigure the audio and room association settings.

  • DSP: The system automatically adjusts the audio settings to perfectly balance the Sub (Gen 3) and the paired Sonos component for best performance. All of the filter settings, active equalization, and time alignment are done digitally through a state-of-the-art Digital Signal Processor (DSP).
  • TruePlay: Trueplay software (for Apple iOS only) dynamically tunes the speaker to the unique acoustics of the room. Trueplay, an auto-tune app within the Sonos S2 App, uses the microphone in your Apple iOS device to measure how sound reflects off walls, furnishings and other surfaces in a room, and then fine tunes the Sub (Gen 3) to make sure it sounds great no matter where you've placed it.
  • Equalizer: Adjustable EQ settings can be manually tailored in the Sonos S2 Controller app.

Notes:

  • In order to perform Trueplay tuning, the Sonos S2 app for iPhone, iPad or iPod touch running iOS 11.0 or higher is required. This includes iPhone 4s and higher, iPad 2 and higher, as well as iPod touch 5th generation and higher. Trueplay tuning is not available if the "VoiceOver" feature is enabled on your Apple iOS device. Trueplay is currently not compatible with Android.
  • You will need to retune the Sub (Gen 3) using TruePlay, if you move the subwoofer, change the orientation of subwoofer (horizontal vs. vertical), or change the configuration of the speaker setup.

Mounting & Placement Options: The Sonos Sub (Gen 3) is designed to sit 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. The Sonos Sub (Gen 3) is designed to stand upright on the integrated rubber feet. You can also lay the sub horizontally on its side, if desired.

  • If you place the Sub (Gen 3) vertically flush against a wall, make sure not to block the front acoustic slot port.
  • If you place the Sub (Gen 3) horizontally on the floor, don't put anything on top of it. Leave at least 1" of clearance along the top of the Sub (Gen 3) if placing under furniture.

Note: Placing the Sub (Gen 3) in a very confined space can affect the dispersion of the sound.

Sonos Wireless Multiroom Audio Eco-System: The Sub (Gen 3) is part of the Sonos wireless multiroom audio eco-system consisting of a family of wireless network speakers, players, and amplifiers. Start with a single Sonos product and add more Sonos products over time. With multiple zones, you can play the same or different songs in different rooms of your home. Compatible distributed audio sources include internet radio, online music services, local network music libraries, as well as hardwired inputs. Up to 32 Sonos devices and 16 groups can be connected in one system. The Sonos Amp is compatible with the new Sonos S2 operating system (OS) and the older Sonos S1 operating system (OS).

  • Sonos S2 OS Compatible Products: The Sonos Five, ARC, Sub (Gen 3), and any Sonos products released after May 2020 will only be compatible with Sonos S2.
  • Sonos S2 and S1 OS Compatible Products: The Sonos Play:1, Play:3, Play:5 (Gen 2), Playbase, Playbar, Connect (Gen 2), Connect:Amp (Gen 2), One (Gen 1/2), One SL, Beam, Amp, Port, Boost, Move, and Sub (Gen 1/2) support both Sonos S2 and S1 operating systems.
  • Sonos S1 OS Compatible Products: The Sonos CR200 Controller, Zone Player, Bridge, Connect (Gen 1), Connect: Amp (Gen 1), and Play: 5 (Gen 1) will only support the older S1 operating system.

Notes:

  • If you have have both, older "legacy" Sonos products and newer Sonos products in your system, you have the option to create two separate eco-systems - one that will be controlled with the older Sonos S1 controller app and the other that will be controlled by the newer Sonos S2 controller app.

Detachable AC Power Cord: The Sonos Sub (Gen 3) operates on standard household current using the supplied detachable 6.5' AC power cord. The Sub (Gen 3) is not battery powered.

Intuitive Control

Powerful CPU: The Sonos Sub (Gen 3) features updated internal technology, including increased memory and a more powerful CPU; plus a new join button for simpler wireless connection.

Sonos S2 App: Sonos S2 is a new app (for Apple iOS 11.0+ / Android OS 7.0+ / Mac OSX 10.11+ / Windows 7+) that powers the next generation of Sonos products. The Sonos S2 app offers new features, usability updates, and more personalization moving forward. The updated app makes it even simpler for you to search for content, control the sound, and personalize your listening experience. Use the Sonos S2 app to setup your Sonos speaker system, control your Sonos speaker system, stream your favorite internet radio stations and online music services, access local network music libraries, and personalize your speaker system.

  • Setup: The app lets you easily setup the Sonos speaker system. Get step-by-step instructions for setting up a new system and/or adding more speakers to your system.
  • Control: With the Sonos S2 app, you can control all your Sonos speakers, soundbars, and components. Adjust volume levels, group products to play in sync, or play something different in every room.
  • Music & Radio: The Sonos S2 app brings together hundreds of internet radio stations and online music services.You also get access to local network music libraries on your smartphone, tablet, laptop, or desktop computer. Use the app to browse all your music, podcasts, radio, and audiobooks all in one place.
  • Personalized Settings: Save favorites and room groups to My Sonos to get to the music faster, create alarms so you can wake up to a favorite radio station or playlist, filter out explicit content, and more.
  • Security: Enhanced protocols, including support for elliptic curve cipher suites in SSL/TLS, keep your system safer and your data more secure.

Notes:

  • The Sonos Sub (Gen 3) is not compatible with the older Sonos S1 Controller app and requires the new Sonos S2 Controller app.
  • Some older Sonos products ("legacy" products) will not support the advances of the S2 app due to their memory and processing power. If you own any of these products, you can continue to use your system as you do today. See System Requirements for more details.

Optional Voice Control: You can control your Sonos system through any Alexa or Google Assistant enabled device (including the Sonos One, Sonos Beam, Amazon Echo, and Google Home - all sold separately). Specific control functions will vary by digital voice assistant.

  • Amazon Alexa: You can ask Alexa to play music on a specific Sonos device in an specific room of your home from these featured music services (Apple Music, Amazon Music, TuneIn, Pandora, iHeartRadio, SiriusXM, & Spotify). Using the Alexa app, you can group your Sonos products and your Alexa-enabled devices together. This makes it easier for Alexa to control your Sonos products based on which room or area they are in. You can pause, resume, and skip songs, as well as change the volume with all Sonos compatible online music services. Click here for more information regarding Amazon Alexa on Sonos.
  • Google Assistant: You can ask Google to play music on a specific Sonos device in an specific room of your home from these featured music services (Google Play, Spotify, YouTube Music, Pandora, Deezer, Tidal, TuneIn, and iHeartRadio). You can pause, resume, and skip songs, as well as change the volume with all Sonos compatible online music services. Click here for more information regarding Google Assistant on Sonos.
Notes:
  • The Sonos PlayBase does not have a built-in microphone for voice control. A separate Alexa or Google Assistant enabled device is required and sold separately for voice control.
  • You can only configure your Sonos system to work with one digital voice assisant; choose either Alexa or Google Assistant (you cannot use both). You will need to search and enable the Sonos skill from the Alexa or Google Home app on your mobile device or computer. Your Sonos equipment and Amazon Alexa-enabled devices must be on the same wireless network.
  • Sonos and Alexa or Google Assistant work together using a single Amazon or Google account. If you have a second Sonos system in another location, you'll need to use a second Amazon or Google account if you'd like to use Alexa. An Amazon or Google account can only be in use on one Sonos system at a time.

System Requirements

Internet Service Provider: You'll need a high-speed, wired internet service provider connection such as cable, fiber, or DSL. Wireless internet connections such as satellite, mobile hotspots, or 4G LTE routers can experience delays between the internet connection and Sonos and are not supported. Using these types of connections can cause music to not play, skip, or cut out completely.

Wireless Setup: Your network router must broadcast a 2.4GHz signal for Sonos products to connect to. If you have a dual band router (2.4GHz and 5GHz), do not disable the 2.4GHz signal. Wireless-N and Wireless-AC routers should work with Sonos as long as they are still broadcasting over B and G WiFi. Most Wireless-N and AC routers should do this unless manually configured not to.

  • The network must not contain enterprise access points that have been configured to require certificates or other forms of enterprise authentication. If you are using multiple access points, make sure they are all set to the same 2.4GHz wireless channel.
  • Networks using wireless range extenders are known to cause issues with Sonos systems that are configured in a wireless setup. If you need to extend your home WiFi to use Sonos in a wireless setup, we recommend using a WiFi mesh router to do so.
  • Sonos cannot connect to guest networks or networks that use a Port page to login.

Wired Setup Requirements: A Sonos system operating in a wired setup will require one of your Sonos products to remain connected to the router via Ethernet cable at all times. If your Sonos system is in a wired setup and you use a WiFi mesh router with multiple wireless nodes, we recommend wiring your Sonos product directly to the primary wired mesh node. Avoid wiring any Sonos products to the wireless mesh nodes. If you are on a corporate or advanced network, it must not block Spanning Tree Protocol (STP).

Note: Ethernet over Power devices (also known as HomePlugs or Powerline adaptors) are not supported by Sonos. While they may work for some systems, they tend to cause intermittent problems with Sonos. EoP adapters create an added delay between your network and Sonos. If the internet connection is too slow or the delay is too great, it can cause your music to skip or cut out completely or your players to drop off from the network.

Sonos S1 or S2 Controller App: Sonos offers a Sonos Controller app for Apple iOS 11.0+, Android OS 7.0+, Mac OSX 10.11+, and Windows 7+. The Sonos S2 is a new app and operating system (OS) that powers the next generation of products and experiences. In addition to new features, usability updates, and more personalization moving forward, Sonos S2 enables higher resolution audio technologies for music and home theater. Most Sonos products are compatible with S2. Some older Sonos "legacy" products will not support the advances of S2 due to their memory and processing power. The older Sonos "legacy" app is referred to as the Sonos S1 app.

  • Sonos Products That Support the Sonos S1 and S2 Controller App: Play:1, Play:3, Play:5 (Gen 2), Playbase, Playbar, Connect (Gen 2), Connect:Amp (Gen 2), One (Gen 1/2), One SL, Beam, Amp, Port, Boost, Move, Sub (Gen 1/2).
  • Sonos Products That Only Support The New S2 Contoller App: Five, ARC, Sub (Gen 3), and any Sonos products released after May 2020.
  • Sonos Products That Only Support The Old S1 Controller App: CR200 Controller, Zone Player, Bridge, Connect (Gen 1), Connect: Amp (Gen 1), Play: 5 (Gen 1).

Notes:

  • If you have have both, older "legacy" Sonos products and newer Sonos products, you have the option to create two separate eco-systems - one that will be controlled with the older Sonos S1 controller app and the other that will be controlled by the newer Sonos S2 controller app.
  • Click here for more information regarding Sonos "Legacy" S1 versus the new Sonos S2 Operating System and App.

Supported Audio Files: Supported audio files from online music services and local music libraries include MP3, WMA, AAC, OGG, FLAC, ALAC, AIFF, and WAV. Sonos can supports FLAC music files up to 16-bit/44.1kHz for "CD-quality" sound. All supported sample rates include 16kHz, 22.5kHz, 24.0kHz, 32.0kHz, 44.1kHz, and 48kHz. Internet Radio streams are supported only in WMA, MP3, and AAC.

Crutchfield asked: Why did you buy this?
A
My first Sonos surround system needed a matching subwoofer. Tbh most of the reviews I've read say the Arc is enough but I'd like to give the full setup a try to see for myself in my home. [ Micheal  Jul 08, 2020 ]
