The mini is perfect for my smaller living room, but the smaller size doesn’t keep it from throwing out some serious bass. It was super easy to add to the Sonos app and connected with my Arc and LG TV immediately. I love it.

I love the kick this sub adds to my Sonos system. It is very easy to install and integrates flawlessly with the ARC Ultra Soundbar. The wireless connectivity feature avoids the mess of running cables and having to hide them. It is aesthetically pleasing.

I’m new to the Sonos ecosystem, and my first Sonos product was the Sonos one. It sounded good for a midsize living room, and I enjoyed listening to music and other audio files on.
But when I decided to get the sub mini, I notice a HUGE improvement in the quality/clarity of my one speaker. Big improvement on audio quality as well as louder base response.
The sub mini allowed my Sonos One to focus more on audio by minimizing its workload and low frequency sounds. I was still surprised by the difference in quality of music and movies that I would hear.
Sometimes I go to the Sonos app and turn the sub on and off while listening to music, and the quality speaks for itself…Amazing!
A great buy, if you’re not looking to spend $800 on the Sub Gen3 but still want quality base.
I’m looking forward to getting more Sonos speakers for the future.

Look great and sounds great. Can't tell the difference from a gen 3. The mate finish goes with the rest of the sonos line. I have two arcs in the living room one already has a gen 3 sub. This will go on the other arc or it could be a second sub on the first arc. Also have two fives in the living room. All of them playing music at once sound pretty amazing. You can notice a difference with a second sub. You could just turn up the bass on one sub. It does sound even better with two also evens out where the bass is coming from. Seems to be coming from everywhere. Also says made in China. My gen 3 was made in Malaysia.

The Sonos Sub Gen 4 is a fantastic addition to any home theater setup. From the moment I added it, the bass became deeper and more powerful, making movies and music feel much more immersive. Explosions and action scenes hit harder, and the sound feels like it surrounds you, bringing the whole experience to life.
When paired with the Sonos Era 300s and the Sonos Arc Ultra, the sound quality is incredible. The Era 300s handle the mid and high tones with great detail, the Arc Ultra adds rich surround sound, and the Sub Gen 4 fills in the low end with booming bass you can feel. Together, they create a full, lively soundstage that makes watching movies way more exciting.
The main downside is the price but it’s definitely a premium setup. But for the quality and seamless integration Sonos offers, it’s worth it if you want top-tier sound. The wireless design and build quality make it easy to use and stylish too.
If you want your sound to feel alive and immersive, this combo is a killer choice.

These subs put out a nice, deep base without being bulky and taking up space. Two of them sounds great!

This Sonos subwoofer is emasculate. The sound is just like the theater. It’s pairs very well with the Sonos arc ultra. It works great with music as well as thriller, horror, and action movies. I definitely give this 10 stars if I had to. This was one of my greatest purchases and I will be buying more Sonos products.Lets just say everyone wants to come over and enjoy the sound. Pop some popcorn, sit back and enjoy the theatrics!Very easy setup on your phone and it took about 5 minutes.

Small compact size and big sound. I have the standard sub and now the Mini. For the money, the Mini is an excellent buy. I would still recommend the standard sub for larger rooms if you prefer a little more bass. I put the Mini in my kitchen island built-ins. It is completely hidden and connected to in ceiling speakers and fills the bass void perfectly!

Plug and play just about covers how the Sub 4 works: take it out, plug it in, and connect it up with a Sonos system. It is as easy and as seamless as subwoofers get. There’s a lot of bass here, for sure, but the price may not justify the means of getting there, especially when a slightly older model or smaller Sub Mini might get you a solid result for less.

I purchased this subwoofer with the Sonos Arc Ultra soundbar. It was easy to integrate with my tv to replace an existing LG soundbar and system. The sound was at least 10 times better. It is also aesthetically attractive and even my wife did not complain.

I have high expectations of the Sonos brand and this product does not change my overall impression of their products. So you may be wondering why I have 4/5 in my review and that exclusively pertains to the fact that I bought a good rated product and was surprised that some features do not work the way they should. The lights don’t work, there were more scratches than anticipated and it was so dusty I almost returned the item. The “Sonos” logo is supposed to light up during install but that individual issue was not related to the anticipated function of the system. It would have been really easy to setup had the light worked. I had to reset the system and those directions were also easy to follow. Again, always reliable and the sound is always amazing as well.
Although disappointed in the state of the unit, the product itself reminds me why the Sonos products are well worth the cost.

The Sonos Sub (Gen 4) takes a Sonos system to another level. The bass is deep, powerful, and incredibly clean.
I have the Sonos sound bar and it was good but adding the subwoofer completely changed the experience
I was surprised how it only took a few minutes to set up. Plus with Best Buy’s 0% financing made it a no brainer!

Nice subwoofer, I was afraid I might need a bigger model, but this gives me all the bass I need. I am very pleased. Love that is is all Bluetooth connected.

I have an arc paired with era 100’s for surrounds and they do sound great and had some bass however, the sub makes me feel the bass all around and it’s impressive how it chaged the feel of movies. Definitely recommend, specially if you can get it in sale or open box with warranty.

Love this Mini-sub! I already had the Sonos Beam Sound bar with 2 Sonos SL speakers which sounded great, but adding the mini-sub completes the setup.
It's not overwhelming and it fits perfectly underneath the living room side table.
Also, since its wireless(besides the power cable), it makes the area look clean without a bunch of cables everywhere.
The Sound, size, and style are perfect for the living room (or for any room)

Powerful, impactful bass. You definitely feel the sound from this subwooferfer. Plus it's custumizable via the Sonos app. If you like strong, punchy, thumping, clean, tight, non distorted bass this is a great addition to the Sonos Arc Ultra.
