Customer Ratings & Reviews

Not sufficient to add bass to our family room. I'm stuck with it. I needed more powerful!

I bought this subwoofer along with the Beam and 2 SL Ones for my living room in April 2023. Without having any power surges or any justifiable cause, the subwoofer is now unresponsive March 2025. The warranty is 1 year long. Tech Support says they can offer 30% off of a replacement and submit a case to see if I can get a replacement. Unless you enjoy a $400 subwoofer randomly becoming a paperweight less than a year out of warranty, I would STRONGLY suggest to buy aomething else.

I own seven other Sonos speakers and this is the only product I've had difficulty pairing and after several hours I've given up. Sub can be at times paired intially but quits halfway through the pairing process via WiFi. The sub mini simply won't begin pairing when using wired Ethernet and says "Sonos speaker cannot be found, please ensure the speaker is plugged in" and it says this with a giant picture of the sub mini on the screen asking you to pair it. I've tried turning off all wifi devices - nothing. Swapped Ethernet cables, switches - nothing. Factory reset of the sub 10 times - doesn't help. Sometimes it will randomly connect via WiFi and disappear once I try to add it to my beam gen 2 or arc. Other times it will pair with the beam, show "beam +?" And display sub controls but the sub doesn't actually produce base. Several times all goes well and when I attempt to add it to a sound bar two sub minis will appear on the screen and it will sit on that screen for 5 min and then time out. Another odd feature is it will at times pair with the app and allow me to add it to a single Sonos one and work normally but when I try to add it to any other speaker the connect is lost. I've never had a single issue with my sub gen 3 or any other Sonos speaker. I tried pairing the sub gen 3 to these sound bars and have zero issues. Avoid this until Sonos fixes the firmware.

This sound is awesome. Sonos as a whole is glitchy and sometimes cuts in/out but the sound here is great.

The sub is fine, but the software is horrible. I have to factory reset my sub weekly. If sonos doesnt fix this soon I am going to return it

Disappointed with the audio quality. The Sub from previous years seems like a better bang for your buck

No remote included and must use a app that you only can use on a iphone.

Sonos has consistently made changes to their ecosystem that are not in the best interest of the user. Their latest app update is a prime example of this. It is an incomplete app that has broken many major features of their products. For example, you can no longer change the WiFi settings of their WiFi speakers. You can no longer adjust the alarms. The old alarms still occur, you just cannot change them anymore. See the forums for the entire list but you get the picture. I regret spending this much money with them. Denon would be a better choice in retrospect.

The sound of this system is good and clear. but it is not a booming room filling sound.

not enough punch for the buck Slick design but was expecting a little more from this sub

Great bass!! Great addition to my two sonos move speakers.

Sales pitch said better than or equal to Bose. Nope.

The Sonos Sub 4 Wireless Subwoofer – Black adds a whole new level of depth and impact to your sound system. The bass feels powerful yet clean, enhancing movies, music, and shows without overpowering the rest of the audio. Low frequencies come through with strong presence, making action scenes more exciting and music feel fuller and more dynamic. Its wireless design makes setup simple and clutter-free, and once connected, it blends seamlessly with other Sonos speakers. The sleek, modern look fits easily into any room while delivering consistent, distortion-free performance. Overall, the Sub 4 is a premium upgrade that noticeably elevates sound quality and creates a richer, more immersive listening experience.

Incredible waste of money. Worked for about 4 months and now a total brick. Call customer service and be put on a 60+ min hold before you can even talk to anyone. They updated software for the app without proper testing and their customers pay the price . Do not by Sonos. I literally have $1000 of sound equipment and none of it now works.

I like so is products. This is my eighth one. However, I have not connected this one yet.

Marginal improvement in sound quality paired with Beam soundbar. I'm now thinking my money would have been better spent upgrading to the Arc.

1 star because of how terrible the Sonos app is when connecting this sub. I tried to connect it to my patio era 100s but it will connect some of the time. I had to reset the subwoofer every time I wanted to use it and half the time it never worked.

Worked great for 2 Days and will not connect now. Called Sonos Tech support and they tried to help, but were saying it had to do with the WIFI. Might have to return. Read reviews elsewhere before purchasing.

Excellent quality sub that doesn’t disappoint. No need for the larger model.

Connection issues. Terrible customer service. Wasted a day trying to set up with an existing beam and got no where. Wireless or wired, NOTHING worked. Customer service was insufferable. Will be moving on from sonos.
