Customer Ratings & Reviews

The Sonos Sound Ecosystem comes at a premium over others but interconnects and works well. While I would like to be able to manage away from home (e.g. if I forgot to turn off the radio when I left), it works well overall and has excellent sound quality. I added this to our SONOS Beam in our Master Bedroom. While it is not as large as the full-size Gen 3 Sub I have in our Living Room paired with the Arc, this is still fairly substantial in size and heavy. It is not overpowering and gives great sound enhancement for the lower range.

Sonos already offers great sounding speakers and if you need that extra kick this sub is wonderful and it doesn't rattle. Easy to pair just like any Sonos product. There is 1 small draw back that I feel could be fixed with a software update and that is if you turn the sound down from your Sonos speaker (touch controls) it doesn't turn the sub that is paired down as well, you have to adjust from the Sonos app or connect Sonos application. Not a huge deal for me but just wanted to mention it.

Great sub. Looks good and sounds good. Unfortunately its a little small so the output is bad if your room is too big.

Excellent little sun woofer. It surprisingly fills the room with smooth, low end without sounding boxy or (buzzy) distorted. Installation and setup was straight forward and simple. No issues at all in the Bluetooth connectivity. Very satisfied so far.

Easy set up and had excellent base sound. Sleek nice design.

Sounds amazing I added to my Ray soundbar and my two eras on my nightstands in my bedroom and huge difference.

The sonus mini added just the perfect amount of bass to my Arc ultra sound bar. But unexpectedly, I think the sound bar sounds even better now.

I absolutely love the quality of the low frequency coming from this subwoofer! Super clean sound and appearance! Can't go wrong with this bad boy!

very good sub, easy setup and easy to modify. Very sleek design, and even though its the mini, its a decent size and good for an apartment or condo

10/10 would most definitely recommend. We’ve had the arc and era 100’s for months and they sound amazing. Adding the sub4 was seamless and brought our music, movies, and gaming to a whole new dimension!

I am blown away by this sub. It is exactly what my Beam Gen 2 and One SL’s were missing for my little bedroom home theater. It really just ties all the speakers together and allows the Beam to shine and the additional base makes everything seem more visceral and alive. It’s got plenty of oomph for my bedroom which is actually fairly large. The regular Sub likely would have seven overkill and while this is still expensive I wasn’t about to spend the $750+tax for the standard sub. Setup was a complete breeze as is all Sonos equipment. And the true tone calibration is technical wizardry. If you are a Sonos fan and you have the Beam or Ray or whatever then get this. Worth every penny.

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.

I didn't think I needed the sub but picked up while on sale - blown away by the difference it makes. Amazing for movies/tv, but I was very happy how much better it made listening to music (paired with arc ultra). Setting up is simple

recently purchased this Sonos and am thrilled! The build quality is excellent, exceeding my expectations for the price. It’s easy to use and solved my lack of base perfectly. Shipping was fast, and it arrived in great condition. I highly recommend it to anyone seeking reliability."

I have had this for over a month and I love it! The bass is great and you can customize the settings through the app, so the possibilities are endless.

I am truly impressed with the quality of this product. The sound is amazing and it makes my movies feel even more powerful with every single episode.

Amazing small subwoofer with lots of power. Absolutely love it and would recommend it to anyone

Amazing when paired with the Sonos Beam. It punches way above what you think it can or should be capable of.

It sounds super good, I love Best Buy and its attitude towards the customer

This little subwoofer packs a MAJOR punch when paired with the Sonos sound bar. Absolutely love the combo. Really brings the sound to life.
