The greatest stereo sound a compact smart speaker can deliver: For every room

The compact multi-room speaker Smart Soundbox 3 with integrated AirPlay 2 technology, Chromecast built-in and Spotify Connect delivers room-filling sound in an elegant design. The compact and powerful speaker is easy to set up via Wi-Fi with AirPlay or the Google Home app, providing your smart home with music in the best audio quality. With a system output of 120 watts and versatile connection and use options, the active, smart speaker is a match for any room - on its own, stereo with a second Smart Soundbox 3 or as part of a larger multi-room set in conjunction with other models from the Canton Smart series. Once connected to Wi-Fi, your favourite music can be distributed throughout the house at the touch of a button.


Outstanding sound quality, smarter than ever.

Once integrated into the WLAN via AirPlay or Google Home, you can easily stream your favourite music to the Smart Soundbox 3. Simply select the AirPlay 2 or Chromecast icon in your preferred music app (such as Spotify, Apple Music, Deezer, etc.) and start playback. The speakers can be controlled directly from your smartphone or tablet, no matter which room you are in your home. You can use your smartphone to make phone calls while the music is playing, play games, send text messages and leave the room at any time. 

Technology down to the smallest detail.

The Smart Soundbox 3 combines elegant design, top-class sound and great technology. Thanks to the control buttons on the touch panel, it is easy to start music playback, change the volume or control the menu settings - everything is just a touch away. With the 3 memory buttons (presets), your favourite Spotify playlists and sound settings can be set and saved. This means your favourites are immediately at hand - without having to use the smartphone. For playback, just press a button and your favourite music will sound everywhere in your home. 


Multiroom or Singleroom - you decide.

The Canton Smart World opens up many unique connection possibilities: With AirPlay 2 or the Google Home app, your favourite songs can be distributed throughout the house or connected as a single room solution per room to form an individual home cinema set. Additional Smart speakers can be connected wirelessly per room via the internal wireless network - whether as a large home cinema set in combination with Smart products such as Smart Vento 9, Smart Vento 3 or even in combination with our Smart soundbars, the possibilities are flexible and perfect for any room situation, no matter how difficult. 

Select your favourite music - By voice command.

In addition to manual operation via the app, you can also start and pause playback, adjust the volume or operate an entire Canton Smart System by voice. Although there are no built-in microphones in the Smart Soundbox 3, it still offers the highest possible compatibility when it comes to voice control. There are several ways to operate the Smart Soundbox 3 by voice: Use the Siri or Google Assistant voice assistants on your smartphone or an external Apple or Google device of your choice. In this way, you can play your favourite music either at the touch of a button or by voice in any desired room.



Easy setup with Apple AirPlay or Google Home App

With Apple Airplay or the Google Home app, the Smart Soundbox 3 can be conveniently set up and managed from your smartphone. The speaker supports both 2.4 GHz and 5 Ghz WLAN connections. 

Always up to date with automatic software updates 

Once integrated in the WLAN, the Smart Soundbox 3 always stays up to date with automatic software updates. This way, you can receive all new functions on your device via update if desired. 

Music playback via Bluetooth® or 3,5 mm input

Even without a WLAN connection, you can stream music wirelessly to the Smart Soundbox 3 via Bluetooth®. In addition, a playback device can be connected by cable via the 3.5 mm input.
