The addition of a Sub4 to my Sonos system was always an issue in my home as my partner was adamant that the resulting 'BOOM!!' of the bass would not only make for uncomfortable listening, but also would "annoy the neighbours".Since the Sub has been added the the resulting sound has been a 'game changer'. The sound on film and TV isn't loud and booming, but adds a wonderful fullness to the sound. It provides a level of atmosphere to what we are watching that really does add to the viewing experience. On occasion when we are watching something with a bass 'boom', it is sudden and gives depth but not in a way which shakes the windows.I love that I bit the bullet and added a Sub4 to my Sonos system and would recommend to anyone who has a Sonos setup in their home. ... MoreThe addition of a Sub4 to my Sonos system was always an issue in my home as my partner was adamant that the resulting 'BOOM!!' of the bass would not only make for uncomfortable listening, but also would "annoy the neighbours".Since the Sub has been added the the resulting sound has been a 'game changer'.

Love this, was a welcome upgrade to my original sub! A bit punchier, more responsive, especially on movies!The new feel is nicer than the older sub, as this has a matt finish. The setup is also a lot easier, the app detected the new sub and by just tapping my phone on the front, it did the rest!Very happy overall and now looking forward to enjoying movies and music with this. If you're not already a sub owner, this is probably the single biggest upgrade you can have to your existing Sonos system!

Sonos creates some beautiful products, that just work. Sub 4 is no exception, looks great in any room, and fills out the sounds from your music, movies, any media. Pairs well with the system, works in various locations and positions. Thanks to Trueplay tuning, your music sounds so much more balanced. Had mine in a dual sub setup, this gave me a little more presence in the low end. I personally would love a little more sass and thump from my bass speakers. Would like to see additional features for tuning or a larger sub offering altogether.

Set this up with our Sonos Beam (Gen 2), not thinking it would make a huge difference to the audio experience. Boy was I wrong! It brings the home cinema experience to a whole new level. Sound amplified & boosted but not distorted. From movies to music, everything sounds incredible. The sounds wraps around the room and lifts it. Love it!!
I added the Sub 4 to my Beam (Gen 1), and at the same time paired two old Play:3 as rear surrounds. I'd never used my Beam for music until now - the Sub 4 gives so much warmth and depth to my music that it's hard to imagine not having it. Large but easy to hide away if preferred, which is a shame, as it looks great!It was so easy to set-up, which could be done using Ethernet or wifi and was detected no problem in the new Sonos app. Pairing with my Beam (Gen 1) and two old Play:3 speakers I expected issues, but everything went smoothly, and I don't think it has disconnected from the speaker group since.Sat on my sofa with the Sub 4 behind is great, it feels immersive and never once did it rattle or vibrate on the floor, it's rock solid, this thing is quality.

If you're using your Sonos soundbar for TV or movies, you need a sub, and this is a good investment.
The Sonos Sub4 offers a true depth of sound, bringing any audio source to life and offering truly emissive sound. The Sub4 offers some marked improvements over the previous Sub editions, both technically and physically with its stunning matt finish, combined with the usual solid build quality and reliability offered by Sonos.Anyone looking to expand their system and bring true depth and controllable base should consider biting the bullet. You won't regret it. The Sub4 makes the already super flexible, excellent audio of Sonos even better.
Having recently set up the Sonos Arc Ultra Smart Soundbar, I was ready to set up this large but beautifully designed Sonos Sub, Generation 4 wireless subwoofer. It, like the Sonos soundbar, came well packaged in using strong cardboard and little plastic. Having already downloaded the Sonos app it was very simple to add my sub 4 via the app. I simply placed it upright (though it can be laid flat to go under a taller legged sofa), plugged it in and followed the very simple instructions on the app to add it. I tuned the soundbar again, using the very clever Sonos Trueplay, that tests your room for sound including furniture, walls and even soft furnishings to then fine tune for the very best sound, the Sub 4 just perfects the whole sound into a truly immersive ... MoreHaving recently set up the Sonos Arc Ultra Smart Soundbar, I was ready to set up this large but beautifully designed Sonos Sub, Generation 4 wireless subwoofer.

I tuned the soundbar again, using the very clever Sonos Trueplay, that tests your room for sound including furniture, walls and even soft furnishings to then fine tune for the very best sound, the Sub 4 just perfects the whole sound into a truly immersive experience, whether watching an action movie or listening to music, I can feel the sound, without it being overly loud, it's just amazingly like being there. We watched an action movie on DVD, oh my goodness, the difference in sound from the TV was incredible. My husband is a musician and loves music, he is in heaven, listening to his favourite music, I recommend watching last night of the proms via this Sub 4, it's like being in the Albert Hall, we can hear every instrument play, it's fabulous. I didn't think the Sonos soundbar could be improved upon, I was wrong, the Sonos Sub (Gen 4) has truly wowed me by the incredible immersive sounds, I absolutely recommend it to you too.
The bass is incredibly powerful yet precise. Whether I'm listening to music or watching movies, the sound gains a whole new depth that I didn't think was possible. I'm especially impressed by how clearly it delivers low frequencies without any muddiness. After some adjustment in the setup process, the setup was easy and seamlessly. For anyone looking to take their audio experience to the next level, this subwoofer is a must-have. Highly recommended!
I added this to my kitchen setup to see if it would enhance my 'entertaining audio', and I am really pleased. It really transforms the depth of the audio in the room at all volume levels. It give's a new quality to the sound. During dinner with low medium volume it makes the audio really very rich. And then with the volume pumped up it adds the party vibe. As usual for Sonos, the build quality is exceptional, the set up is easy and the app integration and integration with other sonos speakers is seamless. I am sure it would be great in a home theatre setup but used in the kitchen I enjoy sharing the quality audio with all my guests!
Look great and sounds great. Can't tell the difference from a gen 3. The mate finish goes with the rest of the sonos line. I have two arcs in the living room one already has a gen 3 sub. This will go on the other arc or it could be a second sub on the first arc. Also have two fives in the living room. All of them playing music at once sound pretty amazing. You can notice a difference with a second sub. You could just turn up the bass on one sub. It does sound even better with two also evens out where the bass is coming from. Seems to be coming from everywhere. Also says made in China. My gen 3 was made in Malaysia.
