Customer Ratings & Reviews

Great sound! Bass is ambient, this thing projects filling the entire room. Set up and adding to the other speakers was simple and easy.

Plenty of base even for my big open room. I have the mini hooked up with the Arc Ultra and Era 100's and it sounds amazing. More than enough base for movies. I did a lot of research and the Sub Gen 4 might have too much base and need to be turned down. So why pay 2x as much for too much base when the mini is really good.

Just upgraded to sono ultra arc with the sub 4. It has improved in sound. We had the first play bar and sub

We have the ultra arc soundbar the sub 4 wireless subwoofer is the perfect match Easy to set up and make listening to movies and music so much more a Enjoyable

The Sonos Sub Gen 4 is an excellent addition to any Sonos home audio setup, offering deep, distortion-free bass that significantly enhances movies, music, and TV audio. Its design features dual opposing drivers that cancel vibrations and deliver precise low-end frequencies down to 25 Hz.

Amazing bass and the sonos ecosystem and user interface is so easy to get used to

Very clean sound quality. No static or cheap audio quality you get at times with entry level products. This is more of a premium sub.

Love this bass box it sounds awesome with the sonos arc ultra

The sound of the day to day and for special movies changes after we added the subwolfer to our system

I have a high ceiling in my living room and this subwoofer fills up the room with deep bass. Definitely will sticking with Sonos from now on!!

The Sonos S4 sub does an excellent job of replacing my Valodyne HGS-10BG 1250 Watts RMS/3000 Wattts peak sub (HGS stands for High Gain Servo). And I am very happy with my purchase. I would give it a five star performance.

WOW! This little thing is a POWER HOUSE! Without a doubt, I will be buying more. Best investment I have ever made. I am new to the Sonos world... I will never go back to anything else.

Great sound and quality. We really do enjoy the movie like experience, the sounds coming from different directions

Getting this sub to add along the rest of my Sonos system has been a game changer. Solid bass that sounds clean.

This is a great subwoofer. I love that you can place it just about anywhere - even slide it on its side under a couch if you have to. Deep and well-controlled bass - Integrates so well with my Sonos speakers. A little pricey, but worth it.

Seems to improve the clarity of the Arc Ultra by taking over the lowest frequencies.

One of the best ever sound system. Earlier I owned Samsung and decided to try Sonos. I would say I took best decision.

This thing is slim and sleek. The size in relation to the output is crazy! Scalability is performed with ease via the Sonos App. Get the bigger option even for small spaces. Spend the extra money - you’ll be glad you did.

Excellent complement to the arc ultra. The combination adds richness the overall sound.

An excellent price for a small subwoofer with a clear and powerful sound!
