Take your listening to the next Level with the Sonos SUB

The Sonos SUB. An absolute show-stopper of a piece of kit. In this blog, we explore why the SUB will dramatically improve most Sonos set ups.

Back to basics: What is the Sonos SUB?

The SUB comes in the form of an aesthetically-pleasing box shape acting as the bass HQ for your content. The low frequencies of sound get converted into deep, rich bass, giving you that rumble, vibrating sound effect you might hear more clearly in a cinema in a high action movie.

Old subwoofers are renowned for being ugly, taking up huge amounts of space in the living room, with wires running everywhere, not to mention producing large amounts of vibration and rattling if you touched it, which was slightly unnerving. 

A good perk about the Sonos SUB is that you get zero cabinet rattle and simply plug it in to power and pair wirelessly with any Sonos speaker. Now the SUB is in its second generation, it’s quite a good looker too.

It comes with two colour choices: gloss black or the newer gloss white and has undergone a few cosmetic upgrades to the first generation, coming in the form of a slight bevel in the corner, a newly painted oblong slit in the middle and a slightly smaller Sonos logo.

How does it work?

Very easily. Simply plug it in to any power socket and pair the SUB wirelessly with any Sonos speaker(s) you like, all done in a few simple steps through the Sonos app. 

Our ideal choices

As mentioned previously, the SUB will pair with any Sonos speaker you own but it pays to be smart about which speakers you pair it with. 


Stereo Pair of PLAY:1s or Ones - A pair of PLAY:1s or Ones is one of our most popular purchase choices due to them being so versatile, affordable and maintaining surprisingly powerful sound. However, the small size comes at a cost to the bass response. Adding a SUB to this set up produces one of the highest levels of difference and your music will thank you for it. 


PLAYBASE, PLAYBAR or Beam - The Sonos SUB works perfectly with any of these components. Due to them both being physically wider speakers, the soundstage is naturally better than what you’d find in a PLAY:1, PLAY:3 or PLAY:5. Couple this with the extra layer of boom you get from a Sonos SUB and you’re on to a winner. This is hands down one of the best sounds you will hear, perfect for music or TV/films alike.

FAQ: Should I add a SUB to my PLAY:5?

We are an honest retailer and would never want our customers to unnecessarily overspend. When we get asked this question, we normally say, 9 times out of 10, it’s a little bit overkill for most people. Unless, you are a passionate basshunter, the PLAY:5s as a stereo pair would provide more than enough bass for most customers.

FAQ: Does it matter where I place the SUB?

The Sonos SUB has the added benefit of being non-directional meaning wherever you place the SUB in the room, has no impact on the resulting sound for that room. That means you have full flexibility to put it literally anywhere in the room, as long as it has enough clear space to push the air out from.

Most customers choose to position it standing upright on the floor, next to the TV but there is nothing stopping you from laying it flat underneath your sofa if you wanted to! Just make sure you don’t hide it in an enclosed cabinet as this will limit its effect.

FAQ: Should I worry about how loud it is for my neighbours?

The Sonos SUB is undoubtedly a very powerful piece of hardware which sometimes raises concerns for customers about noise, especially if it is going into an apartment. Our advice would be to try and position the unit near a wall where there are no adjoining properties to restrict the amount of bass that can be heard through the walls.

There are also settings in the Sonos app that let you adjust the volume of the SUB or apply Night Mode. This would reduce the impact of extremely low frequencies that penetrate through walls such as explosions or particularly bass-heavy parts of a track, so you don’t wake the neighbours if you’re listening at night.



The difference you hear between a Sonos player with and without a SUB is drastic. Just have a read of some of the reviews of the SUB from our customers.

A good question to ask yourself would be "would you prefer to have a surround sound effect or much deeper bass and depth, or both?" The good thing about Sonos is there is no pressure to buy all the equipment at once. Many customers start off with a PLAYBAR or PLAYBASE, then add the SUB at a later date and round off the set up with two PLAY:1s or Ones as surround rears.


Can I hear it before I buy it?

Of course, words will never be as effective as coming in and listening to it with your own ears. That’s why we opened a dedicated Sonos listening pod in Cheltenham so you can come in and make your own mind up about it. Find out more about the pod here.
