Sonos Sub Review Wireless Subwoofer for Deep Bass

Sonos Sub Review Wireless Subwoofer for Deep Bass

Sonos started an inventive way of listening to music 20 years ago in California. At that time, who knew that the company would become a leader in high-performance wireless speakers over the years.

Sonos Sub made of simple lines and fantastic sound entered into many music lovers’ hearts and created fans’ and followers’ armies.

Later on, Sonos entered the home theater market with soundbars and scored once again. People changed their way of thinking about soundbars.

The first wireless subwoofer from Sonos came in 2012. Today we have the third generation of this great addition to the Sonos family.


  • Beautiful design
  • Powerful bass even at high levels
  • Adjustable bass levels
  • Easy integration with other Sonos speakers


  • Very pricy
  • Large cabinet
  • Only works with Sonos system


The Sonos Sub is large and has a size of a PC tower, shaped like the letter O. The dimensions are 15.3 x 15.8 x 6.2 inches and comes in black and white, both glossy. There is a rumor that a non-glossy version will come out soon that will be a bit cheaper. The cabinet weighs 36.3 lbs and has only a power cable, a cleaning shammy, and felt feet as accessories.

The subwoofer is very eye-pleasing and doesn’t have many things on the surface. The Sonos logo is on the front, and the status light and Join button for the wireless network are on the left panel.

At the subwoofer’s center, there are two oval, six-inch drivers in a push-pull arrangement. According to Sonos, this way eliminates the cabinet’s rattling. Two Class-D amplifiers power the drivers, allowing the subwoofer to go down to 25 Hz, while the highest crossover frequency is 110 Hz.

The subwoofer comes with rubber feet, and it can be in a standing position or mounted on its size. In case you want it on the side, you need to apply the felt feet. The positioning won’t change the sound quality, but be aware that the adhesive is strong, and you will find it difficult to change it once the feet are in their position.

When placed vertically, the Sonos Sub sits on four feet. The feet help minimize the vibrations transferring to the floor and provide space under the device for two connections: the power cable and Ethernet port. Too bad there is no Ethernet cable for the port, considering the price of the device.

There is no Bluetooth connectivity for the Sonos Sub, only wireless, and you need an 802.11b/g 2.4 GHz router.

The Sonos Sub setup with an already existing Sonos system is effortless, which is typical for the Sonos. The company has a fantastic app that allows you to set up any speaker. All you need is Wi-Fi, and the app takes care of the rest, such as calibration and adjustment of the subwoofer’s settings, measurement of the room’s acoustics, adjustment of the volume compared to the other speakers in the room, etc.

By default, the crossover frequency is at 80 Hz. It means that the speakers will start to cut off at this point, and the subwoofer starts the output audio. The 80 Hz is not obligatory, and you can change the adjustment between 50 Hz and 110 Hz, all according to your preference and the size of the room.

You should be aware that the Sonos subwoofer only works with Sonos speakers but can’t be used with the Sonos Amp. The Sonos Amp has a subwoofer connection, and that is ideal for pairing the subwoofer with speakers that are not Sonos.

Sound quality of Sonos Sub

Because Sonos Sub works with any Sonos speaker configuration, the sound might vary depending on what you already have.

The default volume level is 0 (between -15 to 15), and at this point, you get the hint of what this subwoofer is capable of and how powerful it can be.

Having level 5 is more than enough when watching movies, for example. Watching action films is such a pleasure because you can hear all the lows of explosions and car crashes that create such a rumble without disturbing the balance of all the frequencies. Older movies can handle higher levels without any problems, and it does make a difference watching movies with a subwoofer included. It gives you a feeling of being at the cinema.

If you listen to music with more considerable sub-bass content, going to too higher levels won’t sound good. Sometimes it is even better to reduce the amount of depth, and you can go all the way down to -15.

Although the Sonos Sub will never give you ground-shaking bass and rumble like many other subwoofers, there is one imposing thing. The subwoofer provides an extra dimension and helps other speakers to focus on the mid and high frequencies, while the subwoofer has its eye on the lowest frequencies. This way, it provides clear and quality sound all over the room.


The Sonos Sub is not for everyone, especially not if you don’t have other Sonos speakers. It makes a great addition to the Sonos system if it is not too expensive for you.

You can buy other soundbars and subwoofers that will bring you the bass and the audio experience for much less money. The only difference will be, they are not Sonos.
