Deep responsive bass.

Aris Karagiannis

The sonos sub is MINDBLOWING . I was sceptical given it costs as much if not more than the actual sound bar . Its a must (sadly given its price! ) it completely transforms the sonic experience and adds a whole new dimension

Dominic Heys

Very good sub. Bass booms and shakes the room now. Used trueplay to tune it too the room and then set up the rest by the Sonos app, worth every penny and finished off my Sonos system well.



Nathan Webber

A great bit of kit, looks good and finishes off the system. I have mine paired with a Playbase and 2 Play 5's as surround speakers. Might sound like overkill, but you can set the surrounds to automatically play louder when playing music which means you get the best of both worlds. I've put off buying one for years, wish I had made the decision sooner.


Unbelievably good piece of kit, expensive butYou get what you pay for. I was the weight of the box with the quality of the build. Easy to set up and link with my Sonos system, and the sound quality has to be heard to be believed.

I always thought the playbar had a decent amount of bass, never really thought it lacking and still don’t but the sub adds a whole new level of audio pleasure. Find it balances nicely with the play bar and really complements all music and telly


My latest purchase, Gen 2 White Subwoofer, got to me via free Next-Day delivery and has been absolutely brilliant when paired with the PlayBar! Simply amazing sound!


What a terrific sound l dont write reviews but this is definitely like being at the cinema and for some strange reason the sound is all around the room, l stood next to the sub where u would think l know its coming from here but its everywhere, great buy it if u can afford it,

Bought the Sonos sub to add to an existing system comprising of a Sonos soundbar and x2 play 1's. It added so much depth to music and added a new depth to movies. Bass you can feel right down to your bones and no vibration or rattle!!! It is a must for Sonos lovers.


No so great at low volumes.......but once you turn it up...WOW!

Anthony Allanson

Sonos Sub is just the best addition to the Sonos range whether adding to Play 1 or ones or adding to playbar & surrounds.. It does subtle if needed and it also does room shake if you want it to, and wow does this thing pack a punch. Its full controllable through the app to tune to your needs. I have neighbours so keep it low late on in the evenings but when I know they are out for the day I can crank it up and really enjoy films and music. You won't regret purchasing the sub. It allows the rest of your speakers to focus on mid and high sounds so the clarity steps up a level too!


Absolutely outstanding bass with no distortion it a great addition to and sonos beam really addsalot of depth. It was a toss up between Bose 700 system with sub and this I listened to both before making a choice and I must say the sonos out performs the dose in every way also the bose is terrible to set up and the bose app in my opinion is useless


Great edition to my sonos playbar makes a huge difference to the overall sound with the sub taking away bass duties to free up the playbar to do what it does best, YouTube music videos come to life know. If I’m honest I was reluctant to spend the amount I did even when it was on at special price I’m glad I did.
