Customer Ratings & Reviews

Decent base with some movies. Not needed for sports watchers. But mixes nicely with the Sonos sound bar.

I’m extremely happy with my Sonos Sub 4 Wireless Subwoofer. The sound quality is outstanding—deep, rich bass that transforms movies and music and adds a whole new level of immersion. Setup was quick and easy via the Sonos app, and the sleek design fits perfectly into my living room décor. This subwoofer integrates flawlessly with the rest of my Sonos system and truly enhances the listening experience, whether I’m watching a movie or enjoying music. Even at high volumes, the bass remains powerful and clear without any distortion. Definitely a premium product that delivers on what it promises. Highly recommend to anyone looking to take their audio system up a notch!

Enhanced my ray soundbar good quality music and television sound

This small modern designed subwoofer adds extra depth and dimension to the great sound offered by the Sonos sound system.

Great addition to the Sonos Beam 2 for a relatively small den. Just what I needed.

Upgraded my Sub 3 to a Sub 4. I definitely feel that there is more bass, subtle, but a deeper bass. As usual, a sleek, modern design, it looks and feels premium. It’s also quite a bit lighter than the 3, which is nice! Sonos bass is deeper and more “punchy” than the previous Samsung surround I had and a definite upgrade. Extremely easy to set up the Sub 4. I may not have figured it out yet, but I do wish there was a “sound field” to set up where one would be for music and the other for movies. My movie bass is always deeper than the music bass and I find myself having to put the bass higher when switching back to movies.

Sound good for small area I need one more for my family

I recently upgraded to the Sonos Arc Sub 4, and it has completely transformed my home audio experience. The sound quality is phenomenal, with crystal-clear dialogue and immersive surround sound. The subwoofer delivers deep, powerful bass that you can feel, making movies and music incredibly engaging. Setup was a breeze, and the sleek design fits perfectly with my living room decor. Highly recommend for anyone looking to elevate their home theater.

If you're looking to take your home audio setup to the next level, the Sonos Subwoofer is a fantastic investment. It delivers deep, room-filling bass that transforms music, movies, and gaming, bringing a whole new dimension to sound. The difference is immediately noticeable—richer tones, powerful lows, and an immersive experience that makes every listening session feel cinematic. Setup is effortless, thanks to wireless connectivity, and the sleek design ensures it fits seamlessly into any space. While it’s a premium product, the upgrade is well worth the cost for anyone serious about high-quality sound. A game-changer for any Sonos system!

If you already have a pre-existing Sonos sound bar, adding the sub 4 will elevate your movie watching experience with refined bass. And if you wanna crank up the bass you can do that through the Sonos app and create a room shaking experience. If one sub four is not enough, you can have the flexibility to have two in that experience alone is worth paying for it. In my opinion if you’re really into watching big Blockbuster movies at home.

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.

This Sub 4 sounds very very good i upgraded from a Sub1 this one is a lot lighter than the original weight wise but sounds just as amazing with tight bass that you can feel Sonos equipment rocks i have now completed my sound system with the ARC Ultra soundbar,this amazing Sub4 and 2 Era 100 for the rear surrounds the sound is out of this world sounds like you are in a movie theater all i can say is WOW

The price is a bit steep. I bit the bullet and got the sound bar and sub on Black Friday Deal. AllI can say is WOW. By far the best sub i have ever heard. It doesnt vibrate the whole house. No, its classier than that. It fills the room with a much more elightening form of bass. I’m amazed.

This product is wonderful, having a wireless subwoofer is just outstanding sounds great and it looks wonderful. I would definitely recommend it to anyone that have a Sonos set up..

Amazing easy to use subwoofer!! App makes everything easy and the bass/lows it creates are superb!!

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.

When I saw that I could not only add a second sub to my Sonos Arc Soundbar, but also have a Gen 4 SUB, AND get it for the same price as a Gen 3, I jumped at the chance! It evened out the bass response of my room, and made the bass even more effortless than it was to begin with. It was easy to add it to my Sonos Home Theater setup. Just like with the Gen 3 SUB, the Gen 4 is very solidly built, and I have never heard it struggle or bottom-out trying to reproduce the lowest bass notes, much less any port noise. Both the Gen 3 and 4 punch WAY above their weight class. And that is saying something coming from someone that has owned Miller & Kreisel and Klipsch subs!

This is an incredible sub! I also happen to have the Nakamichi Shockwafe. This Sonos has a similar room filling base, but it’s connectivity is where it really shines. Nakamichi uses wireless technology to connect, but it often cuts out. You also get stray base rumble. The Sonos is just perfectly connected clear, clean sound. The base is everything you could want from a single dub. It can also lay on its side, and it’s small enough to tuck under our bed. So it’s completely out of sight. This is overkill for a bedroom, but movies in bed with the Sonos surround, are next level awesome, if you’re a stepper!!

Amazing bass from such a compact and beautifully designed subwoofer. Vibrates a little with louder more intense bass, but I'm probably pushing it a little! 99% of the time, it is amazing

The Sonos Sub Gen 4 is an absolute masterpiece of engineering and design. From the moment you unbox it, you can tell this subwoofer means business. The build quality feels solid and refined, with a sleek, minimalist look that fits effortlessly into any modern living room or home theater setup. Pairing it with my existing Sonos system took just a few minutes through the app, and the wireless connection has been rock-solid—no dropouts or sync issues whatsoever. Once connected, the difference in sound is immediate and dramatic. The Sub Gen 4 delivers impossibly deep, clean bass that you feel as much as you hear, yet it never overwhelms or muddies the mid and high frequencies. Whether I’m watching a blockbuster movie, playing music, or streaming TV, the Sub adds a level of richness and depth that’s hard to describe until you experience it firsthand. It takes the already impressive clarity of Sonos speakers like the Arc or Era 300 and elevates them to a truly cinematic level. The dual force-canceling drivers eliminate vibration and rattling, even at high volumes, and the system’s adaptive tuning perfectly balances bass levels with the rest of your setup. It’s powerful, precise, and beautifully controlled. Yes, it’s a premium-priced subwoofer—but you’re paying for premium performance. For anyone serious about their sound, the Sonos Sub Gen 4 is a game-changing upgrade that’s worth every penny.
