Customer Ratings & Reviews

This subwoofer pairs perfectly with the Arc Ultra, and really provides that extra "thump" that the Arc lacks on its own. It also pairs via wifi in the app extremely easily, which was a huge selling point for me!

Calling this a mini sub is hilarious. Not only is it objectively physically large but the bass…. Oh the bass. I have this paired with an Arc Ultra in a medium sized living room with vaulted ceilings and, with EQ set at 6, it FILLS the room with bass. I often need to turn it down so it doesn’t upset the dog. Unless you have a huge space or want an absolutely overwhelming amount of bass, you do not need the full sized sub. This is enough to literally overdo it in most settings. The bass is completely distortion free, even when maxed out, and deep. It shakes my whole couch. Absolutely fantastic when both movies, shows, and video games. I was super skeptical when looking at the price point for all the Sonos stuff but now that I have it, I get it. It’s that good. It’s worth the money. Once you have this you’ll realize - there’s no going back. It’s a total game changer (pun intended).

Outstanding sound in a small footprint. Goodbye Bose this just sells more like a dedicated system than any all in one system that I’ve tried.

Great base and never have had an issue with the device. It connected to the soundbar and surrounding speakers easy

I upgraded to this Sub 4 from a Mini and it has been super interesting comparing the two. Before I dive into that here’s the pros and cons for the Sub 4, generally: Pros: >Incredible room-filling cinematic bass >Relatively compact size, easy to stash behind a couch or next to a media stand >Effective laid flat or standing up >App works well and offers EQ settings Cons: >The price Who is this for? Anyone with an existing Sonos system that wants the best possible cinematic sound. Mine is paired with an Arc Ultra and two Era 100s for surround. I think that’s ideal for a medium-sized room. What’s the difference between this and the mini? The bass from the mini you hear. The bass from the Sub 4 you feel. It doesn’t sound “bass-y” at all. It feels the closest to being in a movie theatre. The bass, even turned up to the max, is just “there.” It surrounds you and adds impact all sorts of media. The mini you heard the bass. It’s still good, but it won’t make your chest vibrate. It sounded like a subwoofer. The Sub 4 is a different experience. Is it worth the money? Look, if you already ponied up for the other Sonos stuff, why not go all the way? It’s a premium, top-of-the-line sub and it’s priced accordingly. I would say yes, it’s worth the money especially if you get it on sale. That said, it depends what your goal is - if you’re just looking for a little extra punch, the Mini might be the way to go.

It really brought our TV/Movie room to life! We have a Sonos bar and two rear 100s. It really compliments and adds the rich bass sound the system needed.

We purchased this sub as an add-on to our Sonos Arc Ultra. We deferred purchasing it until it went on sale and we could use the points from our Sonos Arc Ultra purchase make some weeks before. While the Sonos Arc Ultra is good without the sub, the sub takes it to another level when listening to certain video content or music. You have to install / add the sub through the Sonos app and I had no problems doing so. There is a lot of flexibility in terms of where the sub can be placed. I would recommend placing it facing you but it can even be placed under a couch if you have sufficient room. Note the sub only works with an existing Sonos soundbar.

I loved it! You get what you paid for. It’s expensive but worth it. I bought the beam and the sub and it’s not too loud. I had bought another one and I had to put the volume up and then the *boom* out of nowhere. This one is perfect. However, I must note there is no remote and it’s only done through the phone. There are pros and cons to that…

Good bass with movies with music it’s really amazing and gets your room like a movie theater honestly recommend but if you wnat bigger get a bigger Sonos and it’s going sound the hole block

Deep full bass deliverance from the unit along with a sleek modern look if it wasn't for the power cord you might believe it was decorative piece. I've definitely enjoyed it thus far and see it as a solid brand in comparison to others i own.

I love it, the sound, the design, perfect piece in my living room

This is perfect for our small tv room. You can fee the rumble, and heightens the feel for most movies. Love it!

Added this to my Arc Ultra in my bedroom. Noticeable improvement in watching movies & even better when playing music. Great for a small-med size room.

Outstanding Performance. Great deep bass. Nice and compact. Easy setup using the Sonos App. Must have WIFI. Easily adjustable bass settings to your liking Only downfall is no Bluetooth connectivity. But i dig it.

My first ever sub! I kept contemplating whether or not to get the Sub gen 3 to pair with the Beam gen 2, and then they release this version; it only made sense to give this a try. I’m working with a medium sized space and I am very pleased with it’s performance. The setup and pairing process to the Beam was so simple, and once it was running together I picked a couple of my favorite movie scenes and songs through Spotify to see how it sounded and felt; I still haven’t pushed it past 50% volume and honestly I don’t need to because it sounded amazing. I also love the feature of the two speakers connecting in a way that the Beam is able to enhance the mid and high frequencies more because it knows the Sub is there to carry the low end. Highly recommend giving this a try if you’re new to sound systems and aiming for a budget conscious setup, you won’t be disappointed!

We live in a condo so this smaller subwoofer works great for is!!! Packs plenty of punch! Have it paired with a Sonos Arc and 2 Era 100’s. Couldn’t be happier!!! Sounds fantastic!!! Thought about the Era 300’s, but the 100’s are the right choice for us. From what I see, Sonos has resolved all the issues with their app. Price was right! Got the open box in excellent condition. Just like new!

Actually a really good subwoofer compared to the Sonos ultra the base is rich and super deep makes anything you’re listening to sound super high-quality and immersive

One Gen 4 Sub is an absolute beast. Two of these and youve got some even bass throughout your room, especially if its a dedicated room for your sonos home theater. For me, I have low ceilings, even square room with two Gen 4 subs. One by the TV and the other in the back of the room, facing the couch. I immediately popped in a 4K UHD of Blade Runner 2049 and the hair on my skin was standing up and I had the Harry electric Home Alone haircut going on. Like I said, one is amazing, two is so EVEN!

The Sonos Sub 4 brings deep, powerful bass that completely transforms my home theater and music experience — movies feel cinematic and music hits with punch and clarity you can feel, not just hear. Its force-canceling woofers deliver distortion-free low end that fills the room beautifully and integrates seamlessly with the rest of my Sonos system. Setup was incredibly easy: just plug it in, open the Sonos app, and it paired instantly with my Beam 2 — adding rich, room-shaking bass that the Beam alone simply can’t achieve. Even at moderate volumes, the difference is huge: bass is tight and controlled, dialogue and highs stay clear, and the overall soundstage feels more immersive and balanced. I also appreciate the sleek matte design that matches other Sonos gear, and the flexibility to place it vertically or horizontally under furniture. This is a premium upgrade worth every penny — highly recommended for anyone pairing it with a Beam 2 soundbar!

I don't even know where to start. Let's just say that Joe at San Bernardino knows his stuff but is always willing to think outside of the box. We put our heads together to come up with what I call the "Remote Office Home Theater". This consists of two Sonos One SL's and one Sub Mini. Wow Wow Wow! There is nothing like it in a 12x10 or 24x12 room. Crisp clean bass stamped with the Sonos sound of excellence! The unboxing was mind blowing. Don't judge a book by its cover. The Sub Mini is small and has clean lines. It fits anywhere and is totally discreet. By thinking outside of the box we were able to use the "Remote Office Home Theater" setup to watch TV and listen to music. You do not need a center channel to interface with a TV.
