After months of whispers, Sonos has finally unveiled the much anticipated Sub Mini, a new, more compact version of the Sonos Sub subwoofer.

The Sonos Sub Mini can link with other Sonos speakers and soundbars, such as the Sonos One, Sonos Beam, and the upcoming Sonos Ray, and it is intended to offer deep low-frequency effects. It is obviously not as deep as the bigger Sonos Sub, but the Sub Mini will be much less costly.

Sonos Sub Mini specs

The internal specs of the smaller Sonos Sub Mini are comparable to those of the bigger Sonos Sub (3rd Gen), but less powerful. Small to medium-sized rooms should use the Sub Mini, while larger spaces should use the Sonos Sub.

The cut-out, or Center Tunnel as Sonos refers to it, is designed to circulate air effectively to maximize bass. Internally, there are two 6-inch force-canceling woofers facing each other in a sealed cabinet, promising to produce the low frequencies of the bigger model while attenuating distortion.

The Sonos Sub Mini contains Class-D digital amplifiers and frequency response as low as 25Hz, much like the Sonos Sub (3rd Gen), albeit it lacks some of the higher-end power of the bigger model. The Sub Mini is anticipated to be used with the Sonos Ray, Sonos Beam, Sonos One, One SL, or Symfonisk speakers, whilst the bigger Sub is anticipated to be used with the Arc or Sonos Five speakers.

Sonos Sub Mini features

In terms of features, the Sub Mini has TruePlay tuning, and the audio settings automatically adjust so that the Sub Mini and the Sonos speaker(s) or component(s) it is paired with sound the same.

If you want to change the bass, you can use the Sonos app to change the EQ settings. The paired speaker or soundbar will automatically adjust the volume, and setting it up should be very easy.

The 5GHz Wi-Fi can also speed up the way audio is sent. With the Sonos Sub, you can connect up to three of them together. With the Sonos Sub Mini, this is not possible. You can’t connect a Sonos Sub to a Sonos Sub Mini, either.

  • Trueplay tuning
  • Automatic equalisation

Sonos Sub Mini design

The original Sonos Sub was in the shape of a square, but the Sonos Sub Mini is in the shape of a cylinder. There is still a hole in the middle, just like the bigger Sub, but the device is much smaller and more gentle.

Like most other Sonos products, the Sonos Sub Mini comes in White and Black, and it has a matte finish. The first Sub had a glossy finish, but the third generation changed to a matte finish, like the Sonos Move and Sonos Roam, which are more recent products.

The Sub Mini doesn’t have any buttons, but it does have NFC on top for easy pairing and a Join button on the back in case that doesn’t work. A power port and an Ethernet port are also included.

  • 12 x 9.1 inches, 305 x 230mm, 6.35 kilogram (14lb)
  • Cylindrical shape
  • Color selections in black and white

Sonos Sub Mini setup

Obviously, the Sub Mini will fit into your ecosystem if you already have another Sonos setup altogether. According to Sonos, setting up the Sonos Sub Mini just only a few clicks on the smartphone.

People who like waving their iPhones about their homes will be happy to learn that Sonos has cutting-edge TruePlay tuning technology, which guarantees that, wherever you set the Sub, the sounds it produces will be adjusted for the size of your space.

Sonos Sub Mini vs Sonos Sub

Sonos Sub Mini vs sonos sub


There are some similarities between the Sonos Sub Mini and the original Sonos Sub, but overall, their designs are quite different. The Sub Mini is in the shape of a cylinder with a flat top and an elongated pill-shaped cutout in the middle. It is made to move air quickly to boost bass.

The Sub Mini is 230mm (12 inches) long and 305mm (9.1 inches) wide, and it weighs 6.35kg (14lbs). It also has a matte finish, and you can get it in Black or White.

The Sonos Sub is much bigger and heavier than the Sub Mini. It has a square shape and a matte finish. The top of the Sub is flat, and the sides are also flat, so it can be placed either horizontally or vertically. The Sub, on the other hand, has a hole in the middle like the Sub Mini, and it also comes in Black and White.

The Sub is much bigger than its Mini sibling. It is 389 x 402 x 158mm (15.3 x 15.8 x 6.2 inches) and weighs 16kg (36.3 lbs).


On the back of both the Sonos Sub Mini and Sonos Sub, there is a pairing button, an Ethernet port, and a power port. The NFC chip is on the top of the Sub Mini, making it even easier to pair it with your Sonos system.

Inside the Sonos Sub Mini are class-D amplifiers and two 6-inch woofers that face each other so that they cancel out each other’s sound. The Sub Mini has a sealed cabinet that stops distortion and improves bass response. It also has a frequency response that goes down to 25Hz.

The Sonos Sub also has class-D amplifiers and two carefully designed drivers that are placed so that they face each other. This creates a force-canceling effect and gets rid of rattle and buzz. It, too, has a frequency response down to 25Hz, but at higher frequencies, it is stronger than the Sub Mini.

The Sonos Sub Mini works with 5GHz Wi-Fi, while the Sonos Sub works with either 2.4GHz or 5GHz.


Both the Sonos Sub Mini and the Sonos Sub have some similar features. Both can be paired with a Sonos speaker or soundbar to boost the bass, and both have Trueplay tuning built in to automatically adjust the bass to the room it is in.

Both Sonos Subs will also automatically adjust the volume of the paired speaker or soundbar, but you can also change the EQ settings in the Sonos app if you want to customize the bass.

The Sonos Sub Mini and the Sub (3rd Generation) are different in that the Sub Mini can’t be paired with another Sub Mini or the Sub. The Sub, on the other hand, can be paired with two more Subs to make even more bass.

Your questions

The Sonos Sub Mini does what?

The Sonos Sub Mini, like its bigger brother, the Sonos Sub, and pretty much any other subwoofer, is made to improve the low-frequency response of one or more other speakers.

For example, the Sonos Arc soundbar has its own built-in woofers, but when paired with a Sonos Sub, the Arc’s bass sounds a lot deeper. Like the Sonos Sub, the Sonos Sub Mini will be able to connect wirelessly to other Sonos speakers.

The Sonos Sub Mini not only adds low-frequency effects but also lets the speaker its paired focus more on mid- and high-frequency sounds, which should result in a fuller sound.

Which speakers will work with the Sonos Sub Mini?

Just like the bigger Sonos Sub, the Sonos Sub Mini works with any “amplified, non-portable Sonos product.” This includes the Sonos One, One SL, and Five speakers, as well as the Ray, Beam, and Arc soundbars.

The “non-portable” exception means that the battery-powered Sonos Roam and Move cannot be used. The Sonos Connect or Port won’t work with the Sub Mini, either.

Sonos says that the Sub Mini works “best” with the Beam, Ray, One, and One SL speakers, as well as the SYMFONISK line of products from Ikea.

What does the Sonos Sub Mini look like and how big is it?

The cylindrical, 14-pound Sonos Sub Mini comes in either white or black. It is 12 inches tall and 9.1 inches wide, making it about the size of a small trash can (but don’t try to throw the trash into it).

In addition to being round, the Sub Mini has a thick, oval-shaped slot (or “tunnel,” as Sonos calls it) in the middle, which is similar to how the larger Sonos Sub is made. Sonos says that the slot “moves air efficiently to boost bass.”

If you look into the slot, you will see two speaker drivers facing each other.

Is Alexa, Google Assistant, or Sonos Voice Control built into the Sonos Sub Mini?

You can use Alexa, Google Assistant, or Sonos’ own voice assistant with most Sonos speakers that have microphones.

The Sonos Sub Mini won’t work with a built-in voice assistant because it doesn’t have a mic and is, after all, a subwoofer. The same is true for the bigger Sonos Sub.

What other sound features does the Sonos Sub Mini have?

The Sonos Sub Mini has woofers, but it also has “advanced processing” that, according to Sonos, gives you “the full-tuned low frequencies you’d expect from a much larger subwoofer.” (Of course, the proof is in the pudding, and our full review will tell us soon enough.)

The Sonos Sub Mini also has Sonos’s famous Trueplay feature. Using the microphone on an iPhone or iPad that supports it, Trueplay figures out how the room sounds and adjusts the speaker’s sound to match.

You can also change the volume level of the Sub Mini through the Sonos app.

How does the Sonos Sub Mini work with both wireless and wired connections?

The Sonos Sub Mini has a Wi-Fi radio that works on both 2.4GHz and 5GHz bands.

In a home theater setup, the Sub Mini will connect directly to your Sonos soundbar through the 5GHz spectrum. When paired with a Sonos One or another Sonos speaker, the Sub Mini connects to your Wi-Fi router on either the 2.4GHz or 5GHz bands, depending on how strong the connection is.

The Sub Mini also has a 10/100 (or “fast”) ethernet port if you’d rather connect with a wire.

Can a dual-Sub Mini setup include two Sonos Sub Minis?

Back in December 2020, Sonos added the ability to use two Sonos Subs in a dual-Sub setup. The idea is less to double the bass and more to make the low-frequency response smoother throughout the room.

It’s a cool feature, but in the Sonos ecosystem, only the bigger Sub can be set up with two subwoofers. In other words, you can’t use two Sub Minis together.
