Customer Ratings & Reviews

Excellent bass, though a bit expensive. I was able to find an open box - good item which worked perfectly, just had a little scuff on the side, which is very insignificant given the way I have it positioned. But the quality of the bass with the arc ultra and 2 100’s as surrounds is absolutely incredible. There are some adjustments you can make for the bass via the app, and I personally increased the bass output to +5 since I love that added bass for movies and shows I watch on the D+ app. And setting everything up via the app was seamless and a breeze.

Incredible bass sound in TV and movies that broadcast in stereo or surround. Easy connection and setup. Attractive design that looks good anywhere in room.

This one takes my music experience to the next level. I paired it with Beam 2 . Best part is that I can keep it hidden somewhere behind the couch. Absolutely love it.

Sounds very good and worth every penny gives the base and punch I was looking for

Picked it up launch week (Nov 2025) for $799 in black. Setup & pairing
Added it to my existing Arc + two Era 300 surrounds in under 2 minutes. Trueplay re-ran automatically; the difference was night-and-day. The bass
Deep, tight, and actually musical. Hans Zimmer scores in Dune and Interstellar hit chest-slam levels without ever getting boomy. Hip-hop and EDM (Travis Scott, Fred again..) finally feel complete; the Arc alone always felt a little polite down low. With the Sub 4, you feel 20-30 Hz in your couch on loud scenes, yet dialogue stays perfectly clear. Big upgrades over Sub Gen 3 • Faster processor → zero lag even with heavy Atmos tracks • Deeper extension (advertised 20 Hz vs 25 Hz); I can actually measure and feel it • Dual force-canceling woofers are even better at killing vibration; placed it 18” from the wall and zero rattle • Matte finish looks way classier and hides fingerprints/dog nose prints better Only nitpick
Still $799. Worth it if you’re already invested in Sonos, but that’s real money. Verdict
If you have an Arc (or plan to) and you watch movies or spin Atmos music regularly, the Sub 4 is no longer “nice to have” — it’s basically mandatory for the full experience. My Mini Schnauzer still barks at explosions, but now the floor shakes when he does. 10/10 upgrade, zero regrets.

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!

Hits low and the bass is tight. Pairs easy to other products and is adjustable in presence.

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.

The Sonos Sub Mini is the perfect addition to a smaller room or bedroom setup. I paired it with my Sonos Beam and two Era 100s, and it completely transformed the sound. The design is sleek and compact, and the packaging and setup were just as easy and premium as the rest of the Sonos lineup. Within minutes it was connected and tuned through the Sonos app. The bass is deep, clean, and punchy without being overpowering. It adds so much more depth to movies, TV, and music, making everything feel fuller and more immersive. If you’re on the fence about adding a subwoofer to a Beam or smaller Sonos system, don’t be — the Sub Mini is 100% worth it. It takes an already great system and makes it sound amazing.

Definitely makes a huge difference in the already quality sound of my Sonos system and very easy to setup.

The Sonos - Sub 4 Wireless Subwoofer was a great buy! Much smaller and compact than our previous subwoofer but when it kicks in, WOW, you know it's there! Very happy customers!

Amazing sound... Great bass with clarity. Love it!

The Short- if you’re wondering if it’s gonna be enough, trust me it is it’s amazing and I couldn’t be more happy with my purchase. The Long- I live in a apartment and dont have a big living room by any means. Its about a 16x18 room and i had just recently bought the beam which was very nice sounding. But the next day i got an email saying the arc was on sale for $600 which wasnt told to me when purchasing the bean. So I immediately returned the beam for the arc. I wanted something that worked great by itself. And although the beam does its more like amplifying your tv speakers, not bad but not great. I fell in love with the arc immediately its the only stand alone soundbar that checked all the boxes. But as always i end up wondering what im missing out on lol. So i started researching if im really missing out on alot or if people in apartments thought adding a sub was too much and would bother neighbors. Thats when i found out that adding a sub would really let the Arc sing. Because adding a sub lets the sound bar focus more on mids and highs. But also most people said that the sonos sub was too much. And i was finding mixed results on wether the sub mini was enough. But i came across a really good video of a well respected audio YouTuber it was a asian guy can’t remember his name. And he really broke it down with sound test and everything. I was convinced so I bought one. And it was a fantastic decision. It really opened up the Arc and made it come to life. And I was already happy with the way it sounded without a subwoofer. It’s not gonna shake the house like the normal sub does obviously. But it adds what you’re missing for instance gunshots and movies explosions things like that just sound so much better. And music boy does the music sounds so much better. It is really unbelievable how much they packed into the mini sub. I promise you won’t regret it. If you live in a large house, I would probably definitely go with the full size of. But if you’re working with a small medium, even medium to large living room, the sub mini works perfect I even have to find myself turning it down sometimes. Overall, I couldn’t be more satisfied. And I’m so glad I bought into the son of ecosystem. But be careful because once you upgrade to a Sonos system if you don’t have a top-of-the-line TV, you’re probably gonna be buying one next. Let’s just say it only took me about a month before I bought a brand new LG C5 65 inch TV to go with my sonos set up lol. I hope this helps any of you guys and if you’re thinking about it, definitely pulled the trigger.

I have multiple sonos speakers that i have collected since way back 2013. All of them are still working fine but i’m slowly upgrading them and I’ve got this sub4 which is a significant improvement in terms of set up and sound quality. The design is about the same except it is now in matte finish and hardware and software improvement.

Im so happy with the sound quality. Truly a great sub woofer. The bass is so crisp and it just makes the movie experience so much enjoyable. Very powerful with the ultra arc sonos speaker. Together they make such an amazing duo. Recommend them together to really enjoy the sonos power and quality.

This sub is amazing. It has truly transformed my basement into a quality audio format. Simply blow away by the sound and balance of the the sub and entire system.

I added the Sonos Sub Mini to my setup and it made a real difference. It’s compact but fills the room with solid, tight bass that feels natural and never boomy. Movies just land with more weight, and music has a nice foundation that the soundbar alone couldn’t deliver. Setup was easy through the Sonos app, and Trueplay tuning helped it blend smoothly with my Arc. It disappears visually and still adds depth to everything I watch or listen to. It’s not earth-shaking like a big sub, but for its size and price, it punches well above its weight.

Really nice quality when pairing with arc ultra. Thumps the room wonderfully.

Adding the Sonos Sub 4 to my already excellent Sonos Arc Ultra has completely elevated my listening experience. The Arc Ultra provides the incredible 9.1.4 Dolby Atmos immersion and crystal-clear dialogue, while the Sub 4 handles the bass with spectacular, distortion-free depth. The Sub 4 doesn't just add bass; it frees the Arc to focus on mids and highs, resulting in a richer, fuller, and more detailed soundstage that truly shakes the room during action scenes. Setup was instant through the Sonos app, and the sleek design of both units looks fantastic under the TV. This combination is a premium audio investment that delivers professional-grade, cinematic sound right into your living room.

This Sub packs a serious punch when watching movies or simply listening to music, most of the time i dont even have the settings on high because its so loud.
