1. Do you need the Sonos Sub?

The ultimate question. We usually advise that customers think about how they’re planning to use the system before deciding whether the Sub is for them. If you’re into powerful bass and watch a lot of action or blockbuster movies you’ll likely find merit in the addition of the Sub to really boost the wow factor of those big on-screen moments. Similarly, if your music tastes are on the heavier side, lower frequencies like bass guitars, pipe organs and kick drums will be elevated and shape the music you’re listening to into a more impactful experience. 

The beauty of the Sonos Sub is that it’s fully wireless, meaning it doesn’t need any wire or cable to connect with the rest of your Sonos system. For this reason, it’s entirely possible to integrate the Sub into an already established Sonos system. You can see how you get on with the Sonos Beam, Sonos Arc or other Sonos speakers first and decide whether to add the Sub at a later date. 


Saying this, if you did want to take the plunge and opt for the Sonos Sub along with your other Sonos equipment, we do have a range of discounted Sonos Bundles including the Sonos Sub that you might want to check out:

2. How do I adjust the Sonos Sub's volume?

This is something we get asked quite often, and it might please you to know that settings for the Sonos Sub are customisable within the app. You’ll just need to follow these steps

1. Open the Sonos App on your phone or tablet

2. From the Settings Tab, Select System

3. Select the Room that the Sub is in

4. Select EQ, then move the slider up or down to make adjustments

You’ll be able to both increase and decrease the level of bass you experience from the Sub. For example, if you have a big party you’ll be able to ramp up the bass in anticipation of your guests arriving. If you want to enjoy the latest blockbuster but the kids have gone to bed, just suppress the bass response slightly. You can also use Night Mode with your Sonos soundbar and Sub to suppress bass temporarily when enabled.


3. Can you lay the Sonos Sub flat?

The Sonos Sub has non-directional, force cancelling drivers, meaning it doesn’t matter where in the room you place the Sub, it’ll still sound great. The dual woofers in the Sub face each other within the rectangular void in the centre of the unit meaning it doesn’t matter if you have the product placed right up against a wall or even lying flat. 

This non-directional design makes sure you don’t impede the bass performance no matter how the Sub is positioned, with it even being possible to slot the Sub underneath a Sofa or table. This design also eliminates vibration and cabinet rattle - a win-win!

4. Can I add two Subs to my Sonos System?

As of December 2020, the Sonos system will now allow for two Subs to be paired to the same Sonos product, either the Sonos Beam Gen 2, Sonos Arc, one of Sonos’ older soundbars or the Sonos Amp when set up with a TV. This will double up the low-frequency response of your system to offer a more immersive overall experience. 

This set-up definitely isn’t for everyone, but if you’re looking at adding more dramatic bass and a separated bass soundstage for blockbuster movies and bass-driven music, this could be for you.

5. Is the Sonos Sub worth it?

We appreciate that £749 is a big investment, and as previously covered, the Sonos Sub definitely isn’t for every person. It's hard to quantify the importance of bass and sub-tones to our listening experience, but if you’re the sort of person that gets goosebumps with every explosion on-screen or feels something whenever the bass drops the Sub is probably well worth your time.  

You’ll likely also be impressed by the premium finish of the Sonos Sub too, with its high gloss all-black or all-white design looking the part in any modern home. Its quick pairing and versatility, easily pairing up with most speakers in the Sonos range, makes it a must-have for any large Sonos set-ups.
